-			 The "Artistic License"
-
-				Preamble
-
-The intent of this document is to state the conditions under which a
-Package may be copied, such that the Copyright Holder maintains some
-semblance of artistic control over the development of the package,
-while giving the users of the package the right to use and distribute
-the Package in a more-or-less customary fashion, plus the right to make
-reasonable modifications.
-
-Definitions:
-
-	"Package" refers to the collection of files distributed by the
-	Copyright Holder, and derivatives of that collection of files
-	created through textual modification.
-
-	"Standard Version" refers to such a Package if it has not been
-	modified, or has been modified in accordance with the wishes
-	of the Copyright Holder.
-
-	"Copyright Holder" is whoever is named in the copyright or
-	copyrights for the package.
-
-	"You" is you, if you're thinking about copying or distributing
-	this Package.
-
-	"Reasonable copying fee" is whatever you can justify on the
-	basis of media cost, duplication charges, time of people involved,
-	and so on.  (You will not be required to justify it to the
-	Copyright Holder, but only to the computing community at large
-	as a market that must bear the fee.)
-
-	"Freely Available" means that no fee is charged for the item
-	itself, though there may be fees involved in handling the item.
-	It also means that recipients of the item may redistribute it
-	under the same conditions they received it.
-
-1. You may make and give away verbatim copies of the source form of the
-Standard Version of this Package without restriction, provided that you
-duplicate all of the original copyright notices and associated disclaimers.
-
-2. You may apply bug fixes, portability fixes and other modifications
-derived from the Public Domain or from the Copyright Holder.  A Package
-modified in such a way shall still be considered the Standard Version.
-
-3. You may otherwise modify your copy of this Package in any way, provided
-that you insert a prominent notice in each changed file stating how and
-when you changed that file, and provided that you do at least ONE of the
-following:
-
-    a) place your modifications in the Public Domain or otherwise make them
-    Freely Available, such as by posting said modifications to Usenet or
-    an equivalent medium, or placing the modifications on a major archive
-    site such as uunet.uu.net, or by allowing the Copyright Holder to include
-    your modifications in the Standard Version of the Package.
-
-    b) use the modified Package only within your corporation or organization.
-
-    c) rename any non-standard executables so the names do not conflict
-    with standard executables, which must also be provided, and provide
-    a separate manual page for each non-standard executable that clearly
-    documents how it differs from the Standard Version.
-
-    d) make other distribution arrangements with the Copyright Holder.
-
-4. You may distribute the programs of this Package in object code or
-executable form, provided that you do at least ONE of the following:
-
-    a) distribute a Standard Version of the executables and library files,
-    together with instructions (in the manual page or equivalent) on where
-    to get the Standard Version.
-
-    b) accompany the distribution with the machine-readable source of
-    the Package with your modifications.
-
-    c) accompany any non-standard executables with their corresponding
-    Standard Version executables, giving the non-standard executables
-    non-standard names, and clearly documenting the differences in manual
-    pages (or equivalent), together with instructions on where to get
-    the Standard Version.
-
-    d) make other distribution arrangements with the Copyright Holder.
-
-5. You may charge a reasonable copying fee for any distribution of this
-Package.  You may charge any fee you choose for support of this Package.
-You may not charge a fee for this Package itself.  However,
-you may distribute this Package in aggregate with other (possibly
-commercial) programs as part of a larger (possibly commercial) software
-distribution provided that you do not advertise this Package as a
-product of your own.
-
-6. The scripts and library files supplied as input to or produced as
-output from the programs of this Package do not automatically fall
-under the copyright of this Package, but belong to whomever generated
-them, and may be sold commercially, and may be aggregated with this
-Package.
-
-7. C subroutines supplied by you and linked into this Package in order
-to emulate subroutines and variables of the language defined by this
-Package shall not be considered part of this Package, but are the
-equivalent of input as in Paragraph 6, provided these subroutines do
-not change the language in any way that would cause it to fail the
-regression tests for the language.
-
-8. The name of the Copyright Holder may not be used to endorse or promote
-products derived from this software without specific prior written permission.
-
-9. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR
-IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
-WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE.

-		    GNU GENERAL PUBLIC LICENSE
-		     Version 1, February 1989
-
- Copyright (C) 1989 Free Software Foundation, Inc.
-                    675 Mass Ave, Cambridge, MA 02139, USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-			    Preamble
-
-  The license agreements of most software companies try to keep users
-at the mercy of those companies.  By contrast, our General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  The
-General Public License applies to the Free Software Foundation's
-software and to any other program whose authors commit to using it.
-You can use it for your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Specifically, the General Public License is designed to make
-sure that you have the freedom to give away or sell copies of free
-software, that you receive source code or can get it if you want it,
-that you can change the software or use pieces of it in new free
-programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of a such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must tell them their rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License Agreement applies to any program or other work which
-contains a notice placed by the copyright holder saying it may be
-distributed under the terms of this General Public License.  The
-"Program", below, refers to any such program or work, and a "work based
-on the Program" means either the Program or any work containing the
-Program or a portion of it, either verbatim or with modifications.  Each
-licensee is addressed as "you".
-
-  1. You may copy and distribute verbatim copies of the Program's source
-code as you receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice and
-disclaimer of warranty; keep intact all the notices that refer to this
-General Public License and to the absence of any warranty; and give any
-other recipients of the Program a copy of this General Public License
-along with the Program.  You may charge a fee for the physical act of
-transferring a copy.
-
-  2. You may modify your copy or copies of the Program or any portion of
-it, and copy and distribute such modifications under the terms of Paragraph
-1 above, provided that you also do the following:
-
-    a) cause the modified files to carry prominent notices stating that
-    you changed the files and the date of any change; and
-
-    b) cause the whole of any work that you distribute or publish, that
-    in whole or in part contains the Program or any part thereof, either
-    with or without modifications, to be licensed at no charge to all
-    third parties under the terms of this General Public License (except
-    that you may choose to grant warranty protection to some or all
-    third parties, at your option).
-
-    c) If the modified program normally reads commands interactively when
-    run, you must cause it, when started running for such interactive use
-    in the simplest and most usual way, to print or display an
-    announcement including an appropriate copyright notice and a notice
-    that there is no warranty (or else, saying that you provide a
-    warranty) and that users may redistribute the program under these
-    conditions, and telling the user how to view a copy of this General
-    Public License.
-
-    d) You may charge a fee for the physical act of transferring a
-    copy, and you may at your option offer warranty protection in
-    exchange for a fee.
-
-Mere aggregation of another independent work with the Program (or its
-derivative) on a volume of a storage or distribution medium does not bring
-the other work under the scope of these terms.
-
-  3. You may copy and distribute the Program (or a portion or derivative of
-it, under Paragraph 2) in object code or executable form under the terms of
-Paragraphs 1 and 2 above provided that you also do one of the following:
-
-    a) accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of
-    Paragraphs 1 and 2 above; or,
-
-    b) accompany it with a written offer, valid for at least three
-    years, to give any third party free (except for a nominal charge
-    for the cost of distribution) a complete machine-readable copy of the
-    corresponding source code, to be distributed under the terms of
-    Paragraphs 1 and 2 above; or,
-
-    c) accompany it with the information you received as to where the
-    corresponding source code may be obtained.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form alone.)
-
-Source code for a work means the preferred form of the work for making
-modifications to it.  For an executable file, complete source code means
-all the source code for all modules it contains; but, as a special
-exception, it need not include source code for modules which are standard
-libraries that accompany the operating system on which the executable
-file runs, or for standard header files or definitions files that
-accompany that operating system.
-
-  4. You may not copy, modify, sublicense, distribute or transfer the
-Program except as expressly provided under this General Public License.
-Any attempt otherwise to copy, modify, sublicense, distribute or transfer
-the Program is void, and will automatically terminate your rights to use
-the Program under this License.  However, parties who have received
-copies, or rights to use copies, from you under this General Public
-License will not have their licenses terminated so long as such parties
-remain in full compliance.
-
-  5. By copying, distributing or modifying the Program (or any work based
-on the Program) you indicate your acceptance of this license to do so,
-and all its terms and conditions.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the original
-licensor to copy, distribute or modify the Program subject to these
-terms and conditions.  You may not impose any further restrictions on the
-recipients' exercise of the rights granted herein.
-
-  7. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of the license which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-the license, you may choose any version ever published by the Free Software
-Foundation.
-
-  8. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-	Appendix: How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to humanity, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these
-terms.
-
-  To do so, attach the following notices to the program.  It is safest to
-attach them to the start of each source file to most effectively convey
-the exclusion of warranty; and each file should have at least the
-"copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) 19yy  <name of author>
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 1, or (at your option)
-    any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program; if not, write to the Free Software
-    Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) 19xx name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the
-appropriate parts of the General Public License.  Of course, the
-commands you use may be called something other than `show w' and `show
-c'; they could even be mouse-clicks or menu items--whatever suits your
-program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the
-  program `Gnomovision' (a program to direct compilers to make passes
-  at assemblers) written by James Hacker.
-
-  <signature of Ty Coon>, 1 April 1989
-  Ty Coon, President of Vice
-
-That's all there is to it!

-
-    For those of you that choose to use the GNU General Public License,
-    my interpretation of the GNU General Public License is that no Perl
-    script falls under the terms of the GPL unless you explicitly put
-    said script under the terms of the GPL yourself.  Furthermore, any
-    object code linked with uperl.o does not automatically fall under the
-    terms of the GPL, provided such object code only adds definitions
-    of subroutines and variables, and does not otherwise impair the
-    resulting interpreter from executing any standard Perl script.  I
-    consider linking in C subroutines in this manner to be the moral
-    equivalent of defining subroutines in the Perl language itself.  You
-    may sell such an object file as proprietary provided that you provide
-    or offer to provide the Perl source, as specified by the GNU General
-    Public License.  (This is merely an alternate way of specifying input
-    to the program.)  You may also sell a binary produced by the dumping of
-    a running Perl script that belongs to you, provided that you provide or
-    offer to provide the Perl source as specified by the GPL.  (The
-    fact that a Perl interpreter and your code are in the same binary file
-    is, in this case, a form of mere aggregation.)  This is my interpretation
-    of the GPL.  If you still have concerns or difficulties understanding
-    my intent, feel free to contact me.  Of course, the Artistic License
-    spells all this out for your protection, so you may prefer to use that.

---------------------------------------------------------------------------
-
-Perl is a language that combines some of the features of C, sed, awk and shell.
-See the manual page for more hype.  There's also a Nutshell Handbook published
-by O'Reilly & Assoc.  Their U.S. number is 1-800-338-6887 (dev-nuts) and
-their international number is 1-707-829-0515.  E-mail to nuts@ora.com.
-
-Perl will probably not run on machines with a small address space.
-
-Please read all the directions below before you proceed any further, and
-then follow them carefully.
-
-After you have unpacked your kit, you should have all the files listed
-in MANIFEST.
-
-Installation
-
-1)  Run Configure.  This will figure out various things about your system.
-    Some things Configure will figure out for itself, other things it will
-    ask you about.  It will then proceed to make config.h, config.sh, and
-    Makefile.  If you're a hotshot, run Configure -d to take all the
-    defaults and then edit config.sh to patch up any flaws.
-
-    You might possibly have to trim # comments from the front of Configure
-    if your sh doesn't handle them, but all other # comments will be taken
-    care of.
-
-    (If you don't have sh, you'll have to copy the sample file config.H to
-    config.h and edit the config.h to reflect your system's peculiarities.)
-
-2)  Glance through config.h to make sure system dependencies are correct.
-    Most of them should have been taken care of by running the Configure script.
-
-    If you have any additional changes to make to the C definitions, they
-    can be done in cflags.SH.  For instance, to turn off the optimizer
-    on eval.c, find the line in the switch structure for eval.c and
-    put the command $optimize='-g' before the ;;.  You will probably
-    want to change the entry for teval.c too.  To change the C flags
-    for all the files, edit config.sh and change either $ccflags or $optimize.
-
-3)  make depend
-
-    This will look for all the includes and modify Makefile accordingly.
-    Configure will offer to do this for you.
-
-4)  make
-
-    This will attempt to make perl in the current directory.
-
-    If you can't compile successfully, try adding a -DCRIPPLED_CC flag.
-    (Just because you get no errors doesn't mean it compiled right!)
-    This simplifies some complicated expressions for compilers that
-    get indigestion easily.  If that has no effect, try turning off
-    optimization.  If you have missing routines, you probably need to
-    add some library or other, or you need to undefine some feature that
-    Configure thought was there but is defective or incomplete.
-
-    Some compilers will not compile or optimize the larger files without
-    some extra switches to use larger jump offsets or allocate larger
-    internal tables.  You can customize the switches for each file in
-    cflags.SH.  It's okay to insert rules for specific files into
-    Makefile.SH, since a default rule only takes effect in the
-    absence of a specific rule.
-
-    Most of the following hints are now done automatically by Configure.
-
-    The 3b2 needs to turn off -O.
-    Compilers with limited switch tables may have to define -DSMALLSWITCHES
-    Domain/OS 10.3 (at least) native C 6.7 may need -opt 2 for eval.c
-    AIX/RT may need a -a switch and -DCRIPPLED_CC.
-    AIX RS/6000 needs to use system malloc and avoid -O on eval.c and toke.c.
-    AIX RS/6000 needs -D_NO_PROTO.
-    SUNOS 4.0.[12] needs -DFPUTS_BOTCH.
-    SUNOS 3.[45] should use the system malloc.
-    SGI machines may need -Ddouble="long float" and -O1.
-    Vax-based systems may need to hand assemble teval.s with a -J switch.
-    Ultrix on MIPS machines may need -DLANGUAGE_C.
-    Ultrix 4.0 on MIPS machines may need -Olimit 2900 or so.
-    Ultrix 3.[01] on MIPS needs to undefine WAITPID--the system call is busted.
-    MIPS machines need /bin before /bsd43/bin in PATH.
-    MIPS machines may need to undef d_volatile.
-    MIPS machines may need to turn off -O on cmd.c, perl.c and tperl.c.
-    Some MIPS machines may need to undefine CASTNEGFLOAT.
-    Xenix 386 needs -Sm11000 for yacc, and may need -UM_I86.
-    SCO Xenix may need -m25000 for yacc.  See also README.xenix.
-    Genix needs to use libc rather than libc_s, or #undef VARARGS.
-    NCR Tower 32 (OS 2.01.01) may need -W2,-Sl,2000 and #undef MKDIR.
-    A/UX may appears to work with -O -B/usr/lib/big/ optimizer flags.
-    A/UX needs -lposix to find rewinddir.
-    A/UX may need -ZP -DPOSIX, and -g if big cc is used.
-    FPS machines may need -J and -DBADSWITCH.
-    UTS may need one or more of -DCRIPPLED_CC, -K or -g, and undef LSTAT.
-    dynix may need to undefine CASTNEGFLOAT (d_castneg='undef' in config.sh).
-    Dnix (not dynix) may need to remove -O.
-    IRIX 3.3 may need to undefine VFORK.
-    HP/UX may need to pull cerror.o and syscall.o out of libc.a and link
-	them in explicitly.
-    If you get syntax errors on '(', try -DCRIPPLED_CC or -DBADSWITCH or both.
-    Machines with half-implemented dbm routines will need to #undef ODBM & NDBM.
-    If you have GDBM available and want it instead of NDBM, say -DHAS_GDBM.
-    C's that don't try to restore registers on longjmp() may need -DJMPCLOBBER.
-	(Try this if you get random glitches.)
-    If you get duplicates upon linking for malloc et al, say -DHIDEMYMALLOC.
-    Turn on support for 64-bit integers (long longs) with -DQUAD.
-
-5)  make test
-
-    This will run the regression tests on the perl you just made.
-    If it doesn't say "All tests successful" then something went wrong.
-    See the README in the t subdirectory.  Note that you can't run it
-    in background if this disables opening of /dev/tty.  If "make test"
-    bombs out, just cd to the t directory and run TEST by hand to see if
-    it makes any difference.  If individual tests bomb, you can run
-    them by hand, e.g., ./perl op/groups.t
-
-6)  make install
-
-    This will put perl into a public directory (such as /usr/local/bin).
-    It will also try to put the man pages in a reasonable place.  It will not
-    nroff the man page, however.  You may need to be root to do this.  If
-    you are not root, you must own the directories in question and you should
-    ignore any messages about chown not working.
-
-7)  Read the manual entry before running perl.
-
-8)  IMPORTANT!  Help save the world!  Communicate any problems and suggested
-    patches to me, lwall@netlabs.com (Larry Wall), so we can
-    keep the world in sync.  If you have a problem, there's someone else
-    out there who either has had or will have the same problem.
-
-    If possible, send in patches such that the patch program will apply them.
-    Context diffs are the best, then normal diffs.  Don't send ed scripts--
-    I've probably changed my copy since the version you have.  It's also
-    helpful if you send the output of "uname -a".
-
-    Watch for perl patches in comp.lang.perl.  Patches will generally be
-    in a form usable by the patch program.  If you are just now bringing up
-    perl and aren't sure how many patches there are, write to me and I'll
-    send any you don't have.  Your current patch level is shown in patchlevel.h.
-
-
-Just a personal note:  I want you to know that I create nice things like this
-because it pleases the Author of my story.  If this bothers you, then your
-notion of Authorship needs some revision.  But you can use perl anyway. :-)

-Although supplied with the perl package, the perl scripts in this eg

-
-being sure to include any flags that were on the #! line.  A supplied script

-.TH GCP 1C "13 May 1988"
-.SH NAME
-gcp \- global file copy
-.SH SYNOPSIS
-.B gcp
-file1 file2
-.br
-.B gcp
-[
-.B \-r
-] file ... directory
-.SH DESCRIPTION
-.I gcp
-works just like rcp(1C) except that you may specify a set of hosts to copy files
-from or to.
-The host sets are defined in the file /etc/ghosts.
-(An individual host name can be used as a set containing one member.)
-You can give a command like
-
-	gcp /etc/motd sun:
-
-to copy your /etc/motd file to /etc/motd on all the Suns.
-If, on the other hand, you say
-
-	gcp /a/foo /b/bar sun:/tmp
-
-then your files will be copied to /tmp on all the Suns.
-The general rule is that if you don't specify the destination directory,
-files go to the same directory they are in currently.
-.P
-You may specify the union of two or more sets by using + as follows:
-
-	gcp /a/foo /b/bar 750+mc:
-
-which will copy /a/foo to /a/foo on all 750's and Masscomps, and then copy
-/b/bar to /b/bar on all 750's and Masscomps.
-.P
-Commonly used sets should be defined in /etc/ghosts.
-For example, you could add a line that says
-
-	pep=manny+moe+jack
-
-Another way to do that would be to add the word "pep" after each of the host
-entries:
-
-	manny	sun3 pep
-.br
-	moe		sun3 pep
-.br
-	jack		sun3 pep
-
-Hosts and sets of host can also be excluded:
-
-	foo=sun-sun2
-
-Any host so excluded will never be included, even if a subsequent set on the
-line includes it:
-
-	foo=abc+def
-.br
-	bar=xyz-abc+foo
-
-comes out to xyz+def.
-
-You can define private host sets by creating .ghosts in your current directory
-with entries just like /etc/ghosts.
-Also, if there is a file .grem, it defines "rem" to be the remaining hosts
-from the last gsh or gcp that didn't succeed everywhere.
-.PP
-Interrupting with a SIGINT will cause the rcp to the current host to be skipped
-and execution resumed with the next host.
-To stop completely, send a SIGQUIT.
-.SH SEE ALSO
-rcp(1C)
-.SH BUGS
-All the bugs of rcp, since it calls rcp.

-.TH GSH 8 "13 May 1988"
-.SH NAME
-gsh \- global shell
-.SH SYNOPSIS
-.B gsh
-[options]
-.I host
-[options] 
-.I command
-.SH DESCRIPTION
-.I gsh
-works just like rsh(1C) except that you may specify a set of hosts to execute
-the command on.
-The host sets are defined in the file /etc/ghosts.
-(An individual host name can be used as a set containing one member.)
-You can give a command like
-
-	gsh sun /etc/mungmotd
-
-to run /etc/mungmotd on all your Suns.
-.P
-You may specify the union of two or more sets by using + as follows:
-
-	gsh 750+mc /etc/mungmotd
-
-which will run mungmotd on all 750's and Masscomps.
-.P
-Commonly used sets should be defined in /etc/ghosts.
-For example, you could add a line that says
-
-	pep=manny+moe+jack
-
-Another way to do that would be to add the word "pep" after each of the host
-entries:
-
-	manny	sun3 pep
-.br
-	moe		sun3 pep
-.br
-	jack		sun3 pep
-
-Hosts and sets of host can also be excluded:
-
-	foo=sun-sun2
-
-Any host so excluded will never be included, even if a subsequent set on the
-line includes it:
-
-	foo=abc+def
-	bar=xyz-abc+foo
-
-comes out to xyz+def.
-
-You can define private host sets by creating .ghosts in your current directory
-with entries just like /etc/ghosts.
-Also, if there is a file .grem, it defines "rem" to be the remaining hosts
-from the last gsh or gcp that didn't succeed everywhere.
-
-Options include all those defined by rsh, as well as
-
-.IP "\-d" 8
-Causes gsh to collect input till end of file, and then distribute that input
-to each invokation of rsh.
-.IP "\-h" 8
-Rather than print out the command followed by the output, merely prepends the
-host name to each line of output.
-.IP "\-s" 8
-Do work silently.
-.PP
-Interrupting with a SIGINT will cause the rsh to the current host to be skipped
-and execution resumed with the next host.
-To stop completely, send a SIGQUIT.
-.SH SEE ALSO
-rsh(1C)
-.SH BUGS
-All the bugs of rsh, since it calls rsh.
-
-Also, will not properly return data from the remote execution that contains
-null characters.

-.SH SYNOPSIS

-.SH DESCRIPTION
-.I Relink
-relinks the symbolic links given according to the rule specified as the
-first argument.
-The argument is a Perl expression which is expected to modify the $_
-string in Perl for at least some of the names specified.
-For each symbolic link named on the command line, the Perl expression
-will be executed on the contents of the symbolic link with that name.
-If a given symbolic link's contents is not modified by the expression,
-it will not be changed.
-If a name given on the command line is not a symbolic link, it will be ignored.
-If no names are given on the command line, names will be read
-via standard input.
-.PP
-For example, to relink all symbolic links in the current directory
-pointing to somewhere in X11R3 so that they point to X11R4, you might say
-.nf
-
-	relink 's/X11R3/X11R4/' *
-
-.fi
-To change all occurences of links in the system from /usr/spool to /var/spool,
-you'd say

-If no filenames are given on the command line, filenames will be read

-.PP
-For example, to rename all files matching *.bak to strip the extension,
-you might say
-.nf
-
-	rename 's/\e.bak$//' *.bak
-
-.fi
-To translate uppercase names to lower, you'd use

-
-;; To enter perl-mode automatically, add (autoload 'perl-mode "perl-mode")
-;; to your .emacs file and change the first line of your perl script to:
-;; #!/usr/bin/perl --	 # -*-Perl-*-
-;; With argments to perl:
-;; #!/usr/bin/perl -P-	 # -*-Perl-*-
-;; To handle files included with do 'filename.pl';, add something like
-;; (setq auto-mode-alist (append (list (cons "\\.pl$" 'perl-mode))
-;;                               auto-mode-alist))
-;; to your .emacs file; otherwise the .pl suffix defaults to prolog-mode.
-
-;; This code is based on the 18.53 version c-mode.el, with extensive
-;; rewriting.  Most of the features of c-mode survived intact.
-
-;; I added a new feature which adds functionality to TAB; it is controlled
-;; by the variable perl-tab-to-comment.  With it enabled, TAB does the
-;; first thing it can from the following list:  change the indentation;
-;; move past leading white space; delete an empty comment; reindent a
-;; comment; move to end of line; create an empty comment; tell you that
-;; the line ends in a quoted string, or has a # which should be a \#.
-
-;; If your machine is slow, you may want to remove some of the bindings
-;; to electric-perl-terminator.  I changed the indenting defaults to be
-;; what Larry Wall uses in perl/lib, but left in all the options.
-
-;; I also tuned a few things:  comments and labels starting in column
-;; zero are left there by indent-perl-exp; perl-beginning-of-function
-;; goes back to the first open brace/paren in column zero, the open brace
-;; in 'sub ... {', or the equal sign in 'format ... ='; indent-perl-exp
-;; (meta-^q) indents from the current line through the close of the next
-;; brace/paren, so you don't need to start exactly at a brace or paren.
-
-;; It may be good style to put a set of redundant braces around your
-;; main program.  This will let you reindent it with meta-^q.
-
-;; Known problems (these are all caused by limitations in the elisp
-;; parsing routine (parse-partial-sexp), which was not designed for such
-;; a rich language; writing a more suitable parser would be a big job):
-;; 1)  Regular expression delimitors do not act as quotes, so special
-;;       characters such as `'"#:;[](){} may need to be backslashed
-;;       in regular expressions and in both parts of s/// and tr///.
-;; 2)  The globbing syntax <pattern> is not recognized, so special
-;;       characters in the pattern string must be backslashed.
-;; 3)  The q, qq, and << quoting operators are not recognized; see below.
-;; 4)  \ (backslash) always quotes the next character, so '\' is
-;;       treated as the start of a string.  Use "\\" as a work-around.
-;; 5)  To make variables such a $' and $#array work, perl-mode treats
-;;       $ just like backslash, so '$' is the same as problem 5.
-;; 6)  Unfortunately, treating $ like \ makes ${var} be treated as an

-
-;; Description of perl -d interface:
-
-;; A facility is provided for the simultaneous display of the source code
-;; in one window, while using perldb to step through a function in the
-;; other.  A small arrow in the source window, indicates the current
-;; line.
-
-;; Starting up:
-
-;; In order to use this facility, invoke the command PERLDB to obtain a
-;; shell window with the appropriate command bindings.  You will be asked
-;; for the name of a file to run and additional command line arguments.
-;; Perldb will be invoked on this file, in a window named *perldb-foo*
-;; if the file is foo.
-
-;; M-s steps by one line, and redisplays the source file and line.
-
-;; You may easily create additional commands and bindings to interact
-;; with the display.  For example to put the perl debugger command n on \M-n
-;; (def-perldb n "\M-n")
-
-;; This causes the emacs command perldb-next to be defined, and runs
-;; perldb-display-frame after the command.
-
-;; perldb-display-frame is the basic display function.  It tries to display
-;; in the other window, the file and line corresponding to the current
-;; position in the perldb window.  For example after a perldb-step, it would
-;; display the line corresponding to the position for the last step.  Or
-;; if you have done a backtrace in the perldb buffer, and move the cursor
-;; into one of the frames, it would display the position corresponding to
-;; that frame.
-
-;; perldb-display-frame is invoked automatically when a filename-and-line-number
-;; appears in the output.

-Reading my own message, it occurred to me that I didn't quite satisfy the
-request of stef@zweig.sun (Stephane Payrard):
-
-| Does anyone has extended perdb/perdb.el to position the
-| point to the first syntax error? It would be cool.
-
-What I posted is a way to use the "M-x compile" command to test perl scripts.
-(Needless to say, the script cannot be not interactive; you can't provide input
-to a *compilation* buffer).  When creating new Perl programs, I use "M-x
-compile" until I'm sure that they are syntatically correct; if syntax errors
-occur, C-x` takes me to each in sequence.  After I'm sure the syntax is
-correct, I start worrying about semantics, and switch to "M-x perldb" if
-necessary.
-
-Therefore, the stuff I posted works great with "M-x compile", but not at all
-with "M-x perldb".
-
-Next, let me update what I posted.  I found that perl's die() command doesn't
-print the same format error message as perl does when it dies with a syntax
-error.   If you put the following in your ".emacs" file, it causes C-x` to
-recognize both kinds of errors:
-
-(load-library "compile")
-(setq compilation-error-regexp
-  "\\([^ :\n]+\\(: *\\|, line \\|(\\)[0-9]+\\)\\|\\([0-9]+ *of *[^ \n]+\\|[^ \n]+ \\(at \\)*line [0-9]+\\)")
-
-Last, so I don't look like a total fool, let me propose a way to satisfy
-Stephane Payrard's original request (repeated again):
-
-| Does anyone has extended perdb/perdb.el to position the
-| point to the first syntax error? It would be cool.
-
-I'm not satisfied with just the "first syntax error".  Perl's parser is better
-than most about not getting out of sync; therefore, if it reports multiple
-errors, you can usually be assured they are all real errors.
-
-So... I hacked in the "next-error" function from "compile.el" to form
-"perldb-next-error".  You can apply the patches at the end of this message
-to add "perldb-next-error" to your "perldb.el".
-
-Notes:
-   1) The patch binds "perldb-next-error" to C-x~ (because ~ is the shift
-      of ` on my keyboard, and C-x~ is not yet taken in my version of EMACS).
-
-   2) "next-error" is meant to work on a single *compilation* buffer; any new
-      "M-x compile" or "M-x grep" command will clear the old *compilation*
-      buffer and reset the compilation-error parser to start at the top of the
-      *compilation* buffer.
-
-     "perldb-next-error", on the other hand, has to deal with multiple
-      *perldb-<foo>* buffers, each of which keep growing.  "perldb-next-error"
-      correctly handles the constantly growing *perldb-<foo>* buffers by
-      keeping track of the last reported error in the "current-perldb-buffer".
-
-      Sadly however, when you invoke a new "M-x perldb" on a different Perl
-      script, "perldb-next-error" will start parsing the new *perldb-<bar>*
-      buffer at the top (even if it was previously parsed), and will completely
-      lose the marker of the last reported error in *perldb-<foo>*.
-
-   3) "perldb-next-error" still uses "compilation-error-regexp" to find
-      fatal errors.  Therefore, both the "M-x compile"/C-x` scheme and
-      the "M-x perldb"/C-x~ scheme can be used to find fatal errors that
-      match the common "compilation-error-regexp".  You *will* want to install
-      that "compilation-error-regexp" stuff into your .emacs file.
-
-   4) The patch was developed and tested with GNU Emacs 18.55.
-
-   5) Since the patch was ripped off from compile.el, the code is (of
-      course) subject to the GNU copyleft.

-[This file of Tom Christiansen's has been edited to change makelib to h2ph
-and .h to .ph where appropriate--law.]
-
-This directory contains files to help you convert the *.ph files generated my
-h2ph out of the perl source directory into *.pl files with all the
-indirection of the subroutine calls removed.  The .ph version will be more
-safely portable, because if something isn't defined on the new system, like
-&TIOCGETP, then you'll get a fatal run-time error on the system lacking that
-function.  Using the .pl version means that the subsequent scripts will give
-you a 0 $TIOCGETP and God only knows what may then happen.   Still, I like the
-.pl stuff because they're faster to load.
-
-FIrst, you need to run h2ph on things like sys/ioctl.h to get stuff
-into the perl library directory, often /usr/local/lib/perl.  For example,
-    # h2ph sys/ioctl.h
-takes /usr/include/sys/ioctl.h as input and writes (without i/o redirection)
-the file /usr/local/lib/perl/sys/ioctl.ph, which looks like this
-
-    eval 'sub TIOCM_RTS {0004;}';
-    eval 'sub TIOCM_ST {0010;}';
-    eval 'sub TIOCM_SR {0020;}';
-    eval 'sub TIOCM_CTS {0040;}';
-    eval 'sub TIOCM_CAR {0100;}';
-
-and much worse, rather than what Larry's ioctl.pl from the perl source dir has, 
-which is:
-
-    $TIOCM_RTS = 0004;
-    $TIOCM_ST = 0010;
-    $TIOCM_SR = 0020;
-    $TIOCM_CTS = 0040;
-    $TIOCM_CAR = 0100;
-
-[Workaround for fixed bug in makedir/h2ph deleted--law.]
-
-The more complicated ioctl subs look like this:
-
-    eval 'sub TIOCGSIZE {&TIOCGWINSZ;}';
-    eval 'sub TIOCGWINSZ {&_IOR("t", 104, \'struct winsize\');}';
-    eval 'sub TIOCSETD {&_IOW("t", 1, \'int\');}';
-    eval 'sub TIOCGETP {&_IOR("t", 8,\'struct sgttyb\');}';
-
-The _IO[RW] routines use a %sizeof array, which (presumably) 
-is keyed on the type name with the value being the size in bytes.  
-
-To build %sizeof, try running this in this directory:
-
-    % ./getioctlsizes 
-
-Which will tell you which things the %sizeof array needs
-to hold.  You can try to build a sizeof.ph file with:
-
-    % ./getioctlsizes | ./mksizes > sizeof.ph
-
-Note that mksizes hardcodes the #include files for all the types, so it will
-probably require customization.  Once you have sizeof.ph, install it in the
-perl library directory.  Run my tcbreak script to see whether you can do
-ioctls in perl now.  You'll get some kind of fatal run-time error if you
-can't.  That script should be included in this directory.
-
-If this works well, now you can try to convert the *.ph files into
-*.pl files.  Try this:
-
-    foreach file ( sysexits.ph sys/{errno.ph,ioctl.ph} )
-	./mkvars $file > t/$file:r.pl
-    end
-
-The last one will be the hardest.  If it works, should be able to 
-run tcbreak2 and have it work the same as tcbreak.
-
-Good luck.

-# exceptions.pl
-# tchrist@convex.com
-# 
-# Here's a little code I use for exception handling.  It's really just
-# glorfied eval/die.  The way to use use it is when you might otherwise
-# exit, use &throw to raise an exception.  The first enclosing &catch
-# handler looks at the exception and decides whether it can catch this kind
-# (catch takes a list of regexps to catch), and if so, it returns the one it
-# caught.  If it *can't* catch it, then it will reraise the exception
-# for someone else to possibly see, or to die otherwise.
-# 
-# I use oddly named variables in order to make darn sure I don't conflict 
-# with my caller.  I also hide in my own package, and eval the code in his.
-# 
-# The EXCEPTION: prefix is so you can tell whether it's a user-raised
-# exception or a perl-raised one (eval error).
-# 
-# --tom
-#
-# examples:
-#	if (&catch('/$user_input/', 'regexp', 'syntax error') {
-#		warn "oops try again";
-#		redo;

-# newgetopt.pl -- new options parsing
-
-# SCCS Status     : @(#)@ newgetopt.pl	1.13
-# Author          : Johan Vromans
-# Created On      : Tue Sep 11 15:00:12 1990
-# Last Modified By: Johan Vromans
-# Last Modified On: Tue Jun  2 11:24:03 1992
-# Update Count    : 75
-# Status          : Okay
-
-# This package implements a new getopt function. This function adheres
-# to the new syntax (long option names, no bundling).
-#
-# Arguments to the function are:
-#
-#  - a list of possible options. These should designate valid perl
-#    identifiers, optionally followed by an argument specifier ("="
-#    for mandatory arguments or ":" for optional arguments) and an
-#    argument type specifier: "n" or "i" for integer numbers, "f" for
-#    real (fix) numbers or "s" for strings.
-#    If an "@" sign is appended, the option is treated as an array.
-#    Value(s) are not set, but pushed.
-#
-#  - if the first option of the list consists of non-alphanumeric
-#    characters only, it is interpreted as a generic option starter.
-#    Everything starting with one of the characters from the starter
-#    will be considered an option.
-#    Likewise, a double occurrence (e.g. "--") signals end of
-#    the options list.
-#    The default value for the starter is "-", "--" or "+".
-#
-# Upon return, the option variables, prefixed with "opt_", are defined
-# and set to the respective option arguments, if any.
-# Options that do not take an argument are set to 1. Note that an
-# option with an optional argument will be defined, but set to '' if
-# no actual argument has been supplied.
-# A return status of 0 (false) indicates that the function detected
-# one or more errors.
-#
-# Special care is taken to give a correct treatment to optional arguments.
-#
-# E.g. if option "one:i" (i.e. takes an optional integer argument),
-# then the following situations are handled:
-#
-#    -one -two		-> $opt_one = '', -two is next option
-#    -one -2		-> $opt_one = -2
-#
-# Also, assume "foo=s" and "bar:s" :
-#
-#    -bar -xxx		-> $opt_bar = '', '-xxx' is next option
-#    -foo -bar		-> $opt_foo = '-bar'
-#    -foo --		-> $opt_foo = '--'
-#
-# HISTORY 
-# 2-Jun-1992		Johan Vromans	
-#    Do not use //o to allow multiple NGetOpt calls with different delimeters.
-#    Prevent typeless option from using previous $array state.
-#    Prevent empty option from being eaten as a (negative) number.
-
-# 25-May-1992		Johan Vromans	
-#    Add array options. "foo=s@" will return an array @opt_foo that
-#    contains all values that were supplied. E.g. "-foo one -foo -two" will
-#    return @opt_foo = ("one", "-two");
-#    Correct bug in handling options that allow for a argument when followed
-#    by another option.
-
-# 4-May-1992		Johan Vromans	
-#    Add $ignorecase to match options in either case.
-#    Allow '' option.
-
-# 19-Mar-1992		Johan Vromans	
-#    Allow require from packages.
-#    NGetOpt is now defined in the package that requires it.
-#    @ARGV and $opt_... are taken from the package that calls it.
-#    Use standard (?) option prefixes: -, -- and +.
-
-# 20-Sep-1990		Johan Vromans	
-#    Set options w/o argument to 1.
-#    Correct the dreadful semicolon/require bug.

-# Revision 1.2  90/06/11  18:45:30  18:45:30  root ()
-# - Changed 'warn' to 'mail|warning' in test call (to give example of
-#   facility specification, and because 'warn' didn't work on HP-UX).
-# - Fixed typo in &openlog ("ncons" should be "cons").
-# - Added (package-global) $maskpri, and &setlogmask.
-# - In &syslog:
-#   - put argument test ahead of &connect (why waste cycles?),
-#   - allowed facility to be specified in &syslog's first arg (temporarily
-#     overrides any $facility set in &openlog), just as in syslog(3C),
-#   - do a return 0 when bit for $numpri not set in log mask (see syslog(3C)),
-#   - changed $whoami code to use getlogin, getpwuid($<) and 'syslog'
-#     (in that order) when $ident is null,
-#   - made PID logging consistent with syslog(3C) and subject to $lo_pid only,
-#   - fixed typo in "print CONS" statement ($<facility should be <$facility).
-#   - changed \n to \r in print CONS (\r is useful, $message already has a \n).
-# - Changed &xlate to return -1 for an unknown name, instead of croaking.
-# 
-#
-# tom christiansen <tchrist@convex.com>
-# modified to use sockets by Larry Wall <lwall@jpl-devvax.jpl.nasa.gov>
-# NOTE: openlog now takes three arguments, just like openlog(3)
-#
-# call syslog() with a string priority and a list of printf() args
-# like syslog(3)
-#
-#  usage: require 'syslog.pl';
-#
-#  then (put these all in a script to test function)
-#		
-#

-;# These routines are quite efficient and yet are always guaranteed to agree
-;# with localtime() and gmtime().  We manage this by caching the start times
-;# of any months we've seen before.  If we know the start time of the month,
-;# we can always calculate any time within the month.  The start times

-;# current time, since most dates seen in practice are close to the
-;# current date.  Unlike algorithms that do a binary search (calling gmtime
-;# once for each bit of the time value, resulting in 32 calls), this algorithm
-;# calls it at most 6 times, and usually only once or twice.  If you hit
-;# the month cache, of course, it doesn't call it at all.
-
-;# timelocal is implemented using the same cache.  We just assume that we're
-;# translating a GMT time, and then fudge it when we're done for the timezone
-;# and daylight savings arguments.  The timezone is determined by examining
-;# the result of localtime(0) when the package is initialized.  The daylight

-Once upon a time, I wrote a program called pstruct.  It was a perl 
-program that tried to parse out C structures and display their member
-offsets for you.  This was especially useful for people looking at
-binary dumps or poking around the kernel.  
-
-Pstruct was not a pretty program.  Neither was it particularly robust.
-The problem, you see, was that the C compiler was much better at parsing
-C than I could ever hope to be.  
-
-So I got smart:  I decided to be lazy and let the C compiler parse the C,
-which would spit out debugger stabs for me to read.  These were much
-easier to parse.  It's still not a pretty program, but at least it's more
-robust.  
-
-Pstruct takes any .c or .h files, or preferably .s ones, since that's
-the format it is going to massage them into anyway, and spits out
-listings like this:
-
-struct tty {

-Actually, this was generated by a particular set of options.  You can control
-the formatting of each column, whether you prefer wide or fat, hex or decimal,
-leading zeroes or whatever.
-
-All you need to be able to use this is a C compiler than generates
-BSD/GCC-style stabs.  The -g option on native BSD compilers and GCC
-should get this for you.   
-
-To learn more, just type a bogus option, like -\?, and a long usage message
-will be provided.  There are a fair number of possibilities.
-
-If you're only a C programmer, than this is the end of the message for you.
-You can quit right now, and if you care to, save off the source and run it
-when you feel like it.  Or not.
-
-
-
-But if you're a perl programmer, then for you I have something much more
-wondrous than just a structure offset printer.
-
-You see, if you call pstruct by its other incybernation, c2ph, you have a code
-generator that translates C code into perl code!  Well, structure and union 
-declarations at least, but that's quite a bit.  
-
-Prior to this point, anyone programming in perl who wanted to interact
-with C programs, like the kernel, was forced to guess the layouts of the C
-strutures, and then hardwire these into his program.  Of course, when you
-took your wonderfully to a system where the sgtty structure was laid out
-differently, you program broke.  Which is a shame.

-We've had Larry's h2ph translator, which helped, but that only works on
-cpp symbols, not real C, which was also very much needed.  What I offer
-you is a symbolic way of getting at all the C structures.  I've couched
-them in terms of packages and functions.  Consider the following program:
-
-    #!/usr/bin/perl
-
-    require 'syscall.ph';
-    require 'sys/time.ph';
-    require 'sys/resource.ph';
-
-    $ru = "\0" x &rusage'sizeof();
-
-    syscall(&SYS_getrusage, &RUSAGE_SELF, $ru)      && die "getrusage: $!";
-
-    @ru = unpack($t = &rusage'typedef(), $ru);
-
-    $utime =  $ru[ &rusage'ru_utime + &timeval'tv_sec  ]
-	   + ($ru[ &rusage'ru_utime + &timeval'tv_usec ]) / 1e6;
-
-    $stime =  $ru[ &rusage'ru_stime + &timeval'tv_sec  ]
-	   + ($ru[ &rusage'ru_stime + &timeval'tv_usec ]) / 1e6;
-
-    printf "you have used %8.3fs+%8.3fu seconds.\n", $utime, $stime;
-
-
-As you see, the name of the package is the name of the structure.  Regular
-fields are just their own names.  Plus the follwoing  accessor functions are
-provided for your convenience:
-
-    struct	This takes no arguments, and is merely the number of first-level
-		elements in the structure.  You would use this for indexing
-		into arrays of structures, perhaps like this
-
-		    
-		    $usec = $u[ &user'u_utimer
-				+ (&ITIMER_VIRTUAL * &itimerval'struct)
-				+ &itimerval'it_value
-				+ &timeval'tv_usec
-			      ];
-
-    sizeof   	Returns the bytes in the structure, or the member if 
-	     	you pass it an argument, such as
-
-			&rusage'sizeof(&rusage'ru_utime)
-
-    typedef  	This is the perl format definition for passing to pack and
-	     	unpack.  If you ask for the typedef of a nothing, you get 
-	     	the whole structure, otherwise you get that of the member
-	     	you ask for.  Padding is taken care of, as is the magic to 
-	     	guarantee that a union is unpacked into all its aliases.
-	     	Bitfields are not quite yet supported however.
-
-    offsetof	This function is the byte offset into the array of that
-		member.  You may wish to use this for indexing directly
-		into the packed structure with vec() if you're too lazy
-		to unpack it.
-
-    typeof	Not to be confused with the typedef accessor function, this
-		one returns the C type of that field.  This would allow 
-		you to print out a nice structured pretty print of some
-		structure without knoning anything about it beforehand.
-		No args to this one is a noop.  Someday I'll post such 
-		a thing to dump out your u structure for you.
-
-
-The way I see this being used is like basically this:
-
-	% h2ph <some_include_file.h  >  /usr/lib/perl/tmp.ph
-	% c2ph  some_include_file.h  >> /usr/lib/perl/tmp.ph
-	% install 
-
-It's a little tricker with c2ph because you have to get the includes right.
-I can't know this for your system, but it's not usually too terribly difficult.  
-
-The code isn't pretty as I mentioned  -- I never thought it would be a 1000-
-line program when I started, or I might not have begun. :-)  But I would have
-been less cavalier in how the parts of the program communicated with each 
-other, etc.  It might also have helped if I didn't have to divine the makeup
-of the stabs on the fly, and then account for micro differences between my 
-compiler and gcc. 
-
-Anyway, here it is.  Should run on perl v4 or greater.  Maybe less.

-.SH NAME
-perl \- Practical Extraction and Report Language
-.SH SYNOPSIS
-.B perl
-[options] filename args
-.SH DESCRIPTION
-.I Perl
-is an interpreted language optimized for scanning arbitrary text files,
-extracting information from those text files, and printing reports based
-on that information.
-It's also a good language for many system management tasks.
-The language is intended to be practical (easy to use, efficient, complete)
-rather than beautiful (tiny, elegant, minimal).
-It combines (in the author's opinion, anyway) some of the best features of C,
-\fIsed\fR, \fIawk\fR, and \fIsh\fR,
-so people familiar with those languages should have little difficulty with it.
-(Language historians will also note some vestiges of \fIcsh\fR, Pascal, and
-even BASIC-PLUS.)
-Expression syntax corresponds quite closely to C expression syntax.
-Unlike most Unix utilities,
-.I perl
-does not arbitrarily limit the size of your data\*(--if you've got
-the memory,
-.I perl
-can slurp in your whole file as a single string.
-Recursion is of unlimited depth.
-And the hash tables used by associative arrays grow as necessary to prevent
-degraded performance.
-.I Perl
-uses sophisticated pattern matching techniques to scan large amounts of
-data very quickly.
-Although optimized for scanning text,
-.I perl
-can also deal with binary data, and can make dbm files look like associative
-arrays (where dbm is available).
-Setuid
-.I perl
-scripts are safer than C programs
-through a dataflow tracing mechanism which prevents many stupid security holes.
-If you have a problem that would ordinarily use \fIsed\fR
-or \fIawk\fR or \fIsh\fR, but it
-exceeds their capabilities or must run a little faster,
-and you don't want to write the silly thing in C, then
-.I perl
-may be for you.
-There are also translators to turn your
-.I sed
-and
-.I awk
-scripts into
-.I perl
-scripts.
-OK, enough hype.
-.PP
-Upon startup,
-.I perl
-looks for your script in one of the following places:
-.Ip 1. 4 2
-Specified line by line via
-.B \-e
-switches on the command line.
-.Ip 2. 4 2
-Contained in the file specified by the first filename on the command line.
-(Note that systems supporting the #! notation invoke interpreters this way.)
-.Ip 3. 4 2
-Passed in implicitly via standard input.
-This only works if there are no filename arguments\*(--to pass
-arguments to a
-.I stdin
-script you must explicitly specify a \- for the script name.
-.PP
-After locating your script,
-.I perl
-compiles it to an internal form.
-If the script is syntactically correct, it is executed.
-.Sh "Options"
-Note: on first reading this section may not make much sense to you.  It's here
-at the front for easy reference.
-.PP
-A single-character option may be combined with the following option, if any.
-This is particularly useful when invoking a script using the #! construct which
-only allows one argument.  Example:
-.nf
-
-.ne 2
-	#!/usr/bin/perl \-spi.bak	# same as \-s \-p \-i.bak
-	.\|.\|.
-
-.fi
-Options include:
-.TP 5
-.BI \-0 digits
-specifies the record separator ($/) as an octal number.
-If there are no digits, the null character is the separator.
-Other switches may precede or follow the digits.
-For example, if you have a version of
-.I find
-which can print filenames terminated by the null character, you can say this:
-.nf
-
-    find . \-name '*.bak' \-print0 | perl \-n0e unlink
-
-.fi
-The special value 00 will cause Perl to slurp files in paragraph mode.
-The value 0777 will cause Perl to slurp files whole since there is no
-legal character with that value.
-.TP 5
-.B \-a
-turns on autosplit mode when used with a
-.B \-n
-or
-.BR \-p .
-An implicit split command to the @F array
-is done as the first thing inside the implicit while loop produced by
-the
-.B \-n
-or
-.BR \-p .
-.nf
-
-	perl \-ane \'print pop(@F), "\en";\'
-
-is equivalent to
-
-	while (<>) {
-		@F = split(\' \');
-		print pop(@F), "\en";
-	}
-
-.fi
-.TP 5
-.B \-c
-causes
-.I perl
-to check the syntax of the script and then exit without executing it.
-.TP 5
-.BI \-d
-runs the script under the perl debugger.
-See the section on Debugging.
-.TP 5
-.BI \-D number
-sets debugging flags.
-To watch how it executes your script, use
-.BR \-D14 .
-(This only works if debugging is compiled into your
-.IR perl .)
-Another nice value is \-D1024, which lists your compiled syntax tree.
-And \-D512 displays compiled regular expressions.
-.TP 5
-.BI \-e " commandline"
-may be used to enter one line of script.
-Multiple
-.B \-e
-commands may be given to build up a multi-line script.
-If
-.B \-e
-is given,
-.I perl
-will not look for a script filename in the argument list.
-.TP 5
-.BI \-i extension
-specifies that files processed by the <> construct are to be edited
-in-place.
-It does this by renaming the input file, opening the output file by the
-same name, and selecting that output file as the default for print statements.
-The extension, if supplied, is added to the name of the
-old file to make a backup copy.
-If no extension is supplied, no backup is made.
-Saying \*(L"perl \-p \-i.bak \-e "s/foo/bar/;" .\|.\|. \*(R" is the same as using
-the script:
-.nf
-
-.ne 2
-	#!/usr/bin/perl \-pi.bak
-	s/foo/bar/;
-
-which is equivalent to
-
-.ne 14
-	#!/usr/bin/perl
-	while (<>) {
-		if ($ARGV ne $oldargv) {
-			rename($ARGV, $ARGV . \'.bak\');
-			open(ARGVOUT, ">$ARGV");
-			select(ARGVOUT);
-			$oldargv = $ARGV;
-		}
-		s/foo/bar/;
-	}
-	continue {
-	    print;	# this prints to original filename
-	}
-	select(STDOUT);
-
-.fi
-except that the
-.B \-i
-form doesn't need to compare $ARGV to $oldargv to know when
-the filename has changed.
-It does, however, use ARGVOUT for the selected filehandle.
-Note that
-.I STDOUT
-is restored as the default output filehandle after the loop.
-.Sp
-You can use eof to locate the end of each input file, in case you want
-to append to each file, or reset line numbering (see example under eof).
-.TP 5
-.BI \-I directory
-may be used in conjunction with
-.B \-P
-to tell the C preprocessor where to look for include files.
-By default /usr/include and /usr/lib/perl are searched.
-.TP 5
-.BI \-l octnum
-enables automatic line-ending processing.  It has two effects:
-first, it automatically chops the line terminator when used with
-.B \-n
-or
-.B \-p ,
-and second, it assigns $\e to have the value of
-.I octnum
-so that any print statements will have that line terminator added back on.  If
-.I octnum
-is omitted, sets $\e to the current value of $/.
-For instance, to trim lines to 80 columns:
-.nf
-
-	perl -lpe \'substr($_, 80) = ""\'
-
-.fi
-Note that the assignment $\e = $/ is done when the switch is processed,
-so the input record separator can be different than the output record
-separator if the
-.B \-l
-switch is followed by a
-.B \-0
-switch:
-.nf
-
-	gnufind / -print0 | perl -ln0e 'print "found $_" if -p'
-
-.fi
-This sets $\e to newline and then sets $/ to the null character.
-.TP 5
-.B \-n
-causes
-.I perl
-to assume the following loop around your script, which makes it iterate
-over filename arguments somewhat like \*(L"sed \-n\*(R" or \fIawk\fR:
-.nf
-
-.ne 3
-	while (<>) {
-		.\|.\|.		# your script goes here
-	}
-
-.fi
-Note that the lines are not printed by default.
-See
-.B \-p
-to have lines printed.
-Here is an efficient way to delete all files older than a week:
-.nf
-
-	find . \-mtime +7 \-print | perl \-nle \'unlink;\'
-
-.fi
-This is faster than using the \-exec switch of find because you don't have to
-start a process on every filename found.
-.TP 5
-.B \-p
-causes
-.I perl
-to assume the following loop around your script, which makes it iterate
-over filename arguments somewhat like \fIsed\fR:
-.nf
-
-.ne 5
-	while (<>) {
-		.\|.\|.		# your script goes here
-	} continue {
-		print;
-	}
-
-.fi
-Note that the lines are printed automatically.
-To suppress printing use the
-.B \-n
-switch.
-A
-.B \-p
-overrides a
-.B \-n
-switch.
-.TP 5
-.B \-P
-causes your script to be run through the C preprocessor before
-compilation by
-.IR perl .
-(Since both comments and cpp directives begin with the # character,
-you should avoid starting comments with any words recognized
-by the C preprocessor such as \*(L"if\*(R", \*(L"else\*(R" or \*(L"define\*(R".)
-.TP 5
-.B \-s
-enables some rudimentary switch parsing for switches on the command line
-after the script name but before any filename arguments (or before a \-\|\-).
-Any switch found there is removed from @ARGV and sets the corresponding variable in the
-.I perl
-script.
-The following script prints \*(L"true\*(R" if and only if the script is
-invoked with a \-xyz switch.
-.nf
-
-.ne 2
-	#!/usr/bin/perl \-s
-	if ($xyz) { print "true\en"; }
-
-.fi
-.TP 5
-.B \-S
-makes
-.I perl
-use the PATH environment variable to search for the script
-(unless the name of the script starts with a slash).
-Typically this is used to emulate #! startup on machines that don't
-support #!, in the following manner:
-.nf
-
-	#!/usr/bin/perl
-	eval "exec /usr/bin/perl \-S $0 $*"
-		if $running_under_some_shell;
-
-.fi
-The system ignores the first line and feeds the script to /bin/sh,
-which proceeds to try to execute the
-.I perl
-script as a shell script.
-The shell executes the second line as a normal shell command, and thus
-starts up the
-.I perl
-interpreter.
-On some systems $0 doesn't always contain the full pathname,
-so the
-.B \-S
-tells
-.I perl
-to search for the script if necessary.
-After
-.I perl
-locates the script, it parses the lines and ignores them because
-the variable $running_under_some_shell is never true.
-A better construct than $* would be ${1+"$@"}, which handles embedded spaces
-and such in the filenames, but doesn't work if the script is being interpreted
-by csh.
-In order to start up sh rather than csh, some systems may have to replace the
-#! line with a line containing just
-a colon, which will be politely ignored by perl.
-Other systems can't control that, and need a totally devious construct that
-will work under any of csh, sh or perl, such as the following:
-.nf
-
-.ne 3
-	eval '(exit $?0)' && eval 'exec /usr/bin/perl -S $0 ${1+"$@"}'
-	& eval 'exec /usr/bin/perl -S $0 $argv:q'
-		if 0;
-
-.fi
-.TP 5
-.B \-u
-causes
-.I perl
-to dump core after compiling your script.
-You can then take this core dump and turn it into an executable file
-by using the undump program (not supplied).
-This speeds startup at the expense of some disk space (which you can
-minimize by stripping the executable).
-(Still, a "hello world" executable comes out to about 200K on my machine.)
-If you are going to run your executable as a set-id program then you
-should probably compile it using taintperl rather than normal perl.
-If you want to execute a portion of your script before dumping, use the
-dump operator instead.
-Note: availability of undump is platform specific and may not be available
-for a specific port of perl.
-.TP 5
-.B \-U
-allows
-.I perl
-to do unsafe operations.
-Currently the only \*(L"unsafe\*(R" operations are the unlinking of directories while
-running as superuser, and running setuid programs with fatal taint checks
-turned into warnings.
-.TP 5
-.B \-v
-prints the version and patchlevel of your
-.I perl
-executable.
-.TP 5
-.B \-w
-prints warnings about identifiers that are mentioned only once, and scalar
-variables that are used before being set.
-Also warns about redefined subroutines, and references to undefined
-filehandles or filehandles opened readonly that you are attempting to
-write on.
-Also warns you if you use == on values that don't look like numbers, and if
-your subroutines recurse more than 100 deep.
-.TP 5
-.BI \-x directory
-tells
-.I perl
-that the script is embedded in a message.
-Leading garbage will be discarded until the first line that starts
-with #! and contains the string "perl".
-Any meaningful switches on that line will be applied (but only one
-group of switches, as with normal #! processing).
-If a directory name is specified, Perl will switch to that directory
-before running the script.
-The
-.B \-x
-switch only controls the disposal of leading garbage.
-The script must be terminated with _\|_END_\|_ if there is trailing garbage
-to be ignored (the script can process any or all of the trailing garbage
-via the DATA filehandle if desired).
-.Sh "Data Types and Objects"
-.PP
-.I Perl
-has three data types: scalars, arrays of scalars, and
-associative arrays of scalars.
-Normal arrays are indexed by number, and associative arrays by string.
-.PP
-The interpretation of operations and values in perl sometimes
-depends on the requirements
-of the context around the operation or value.
-There are three major contexts: string, numeric and array.
-Certain operations return array values
-in contexts wanting an array, and scalar values otherwise.
-(If this is true of an operation it will be mentioned in the documentation
-for that operation.)
-Operations which return scalars don't care whether the context is looking
-for a string or a number, but
-scalar variables and values are interpreted as strings or numbers
-as appropriate to the context.
-A scalar is interpreted as TRUE in the boolean sense if it is not the null
-string or 0.
-Booleans returned by operators are 1 for true and 0 or \'\' (the null
-string) for false.
-.PP
-There are actually two varieties of null string: defined and undefined.
-Undefined null strings are returned when there is no real value for something,
-such as when there was an error, or at end of file, or when you refer
-to an uninitialized variable or element of an array.
-An undefined null string may become defined the first time you access it, but
-prior to that you can use the defined() operator to determine whether the
-value is defined or not.
-.PP
-References to scalar variables always begin with \*(L'$\*(R', even when referring
-to a scalar that is part of an array.
-Thus:
-.nf
-
-.ne 3
-    $days	\h'|2i'# a simple scalar variable
-    $days[28]	\h'|2i'# 29th element of array @days
-    $days{\'Feb\'}\h'|2i'# one value from an associative array
-    $#days	\h'|2i'# last index of array @days
-
-but entire arrays or array slices are denoted by \*(L'@\*(R':
-
-    @days	\h'|2i'# ($days[0], $days[1],\|.\|.\|. $days[n])
-    @days[3,4,5]\h'|2i'# same as @days[3.\|.5]

-.PP
-Any of these eight constructs may serve as an lvalue,
-that is, may be assigned to.
-(It also turns out that an assignment is itself an lvalue in
-certain contexts\*(--see examples under s, tr and chop.)
-Assignment to a scalar evaluates the righthand side in a scalar context,
-while assignment to an array or array slice evaluates the righthand side
-in an array context.
-.PP
-You may find the length of array @days by evaluating
-\*(L"$#days\*(R", as in
-.IR csh .
-(Actually, it's not the length of the array, it's the subscript of the last element, since there is (ordinarily) a 0th element.)
-Assigning to $#days changes the length of the array.
-Shortening an array by this method does not actually destroy any values.
-Lengthening an array that was previously shortened recovers the values that
-were in those elements.
-You can also gain some measure of efficiency by preextending an array that
-is going to get big.
-(You can also extend an array by assigning to an element that is off the
-end of the array.
-This differs from assigning to $#whatever in that intervening values
-are set to null rather than recovered.)
-You can truncate an array down to nothing by assigning the null list () to
-it.
-The following are exactly equivalent
-.nf
-
-	@whatever = ();
-	$#whatever = $[ \- 1;
-
-.fi
-.PP
-If you evaluate an array in a scalar context, it returns the length of
-the array.
-The following is always true:
-.nf
-
-	scalar(@whatever) == $#whatever \- $[ + 1;
-
-.fi
-If you evaluate an associative array in a scalar context, it returns
-a value which is true if and only if the array contains any elements.
-(If there are any elements, the value returned is a string consisting
-of the number of used buckets and the number of allocated buckets, separated
-by a slash.)
-.PP
-Multi-dimensional arrays are not directly supported, but see the discussion
-of the $; variable later for a means of emulating multiple subscripts with
-an associative array.
-You could also write a subroutine to turn multiple subscripts into a single
-subscript.
-.PP
-Every data type has its own namespace.
-You can, without fear of conflict, use the same name for a scalar variable,
-an array, an associative array, a filehandle, a subroutine name, and/or
-a label.
-Since variable and array references always start with \*(L'$\*(R', \*(L'@\*(R',
-or \*(L'%\*(R', the \*(L"reserved\*(R" words aren't in fact reserved
-with respect to variable names.
-(They ARE reserved with respect to labels and filehandles, however, which
-don't have an initial special character.
-Hint: you could say open(LOG,\'logfile\') rather than open(log,\'logfile\').
-Using uppercase filehandles also improves readability and protects you
-from conflict with future reserved words.)
-Case IS significant\*(--\*(L"FOO\*(R", \*(L"Foo\*(R" and \*(L"foo\*(R" are all
-different names.
-Names which start with a letter may also contain digits and underscores.
-Names which do not start with a letter are limited to one character,
-e.g. \*(L"$%\*(R" or \*(L"$$\*(R".
-(Most of the one character names have a predefined significance to
-.IR perl .
-More later.)
-.PP
-Numeric literals are specified in any of the usual floating point or
-integer formats:
-.nf
-
-.ne 6
-    12345
-    12345.67
-    .23E-10
-    0xffff	# hex
-    0377	# octal
-    4_294_967_296
-
-.fi
-String literals are delimited by either single or double quotes.
-They work much like shell quotes:
-double-quoted string literals are subject to backslash and variable
-substitution; single-quoted strings are not (except for \e\' and \e\e).
-The usual backslash rules apply for making characters such as newline, tab,
-etc., as well as some more exotic forms:
-.nf
-
-	\et		tab
-	\en		newline
-	\er		return
-	\ef		form feed
-	\eb		backspace
-	\ea		alarm (bell)
-	\ee		escape
-	\e033		octal char
-	\ex1b		hex char
-	\ec[		control char
-	\el		lowercase next char
-	\eu		uppercase next char
-	\eL		lowercase till \eE
-	\eU		uppercase till \eE
-	\eE		end case modification
-
-.fi
-You can also embed newlines directly in your strings, i.e. they can end on
-a different line than they begin.
-This is nice, but if you forget your trailing quote, the error will not be
-reported until
-.I perl
-finds another line containing the quote character, which
-may be much further on in the script.
-Variable substitution inside strings is limited to scalar variables, normal
-array values, and array slices.
-(In other words, identifiers beginning with $ or @, followed by an optional
-bracketed expression as a subscript.)
-The following code segment prints out \*(L"The price is $100.\*(R"
-.nf
-
-.ne 2
-    $Price = \'$100\';\h'|3.5i'# not interpreted
-    print "The price is $Price.\e\|n";\h'|3.5i'# interpreted
-
-.fi
-Note that you can put curly brackets around the identifier to delimit it
-from following alphanumerics.
-Also note that a single quoted string must be separated from a preceding
-word by a space, since single quote is a valid character in an identifier
-(see Packages).
-.PP
-Two special literals are _\|_LINE_\|_ and _\|_FILE_\|_, which represent the current
-line number and filename at that point in your program.
-They may only be used as separate tokens; they will not be interpolated
-into strings.
-In addition, the token _\|_END_\|_ may be used to indicate the logical end of the
-script before the actual end of file.
-Any following text is ignored, but may be read via the DATA filehandle.
-(The DATA filehandle may read data only from the main script, but not from
-any required file or evaluated string.)
-The two control characters ^D and ^Z are synonyms for _\|_END_\|_.
-.PP
-A word that doesn't have any other interpretation in the grammar will be
-treated as if it had single quotes around it.
-For this purpose, a word consists only of alphanumeric characters and underline,
-and must start with an alphabetic character.
-As with filehandles and labels, a bare word that consists entirely of
-lowercase letters risks conflict with future reserved words, and if you
-use the
-.B \-w
-switch, Perl will warn you about any such words.
-.PP
-Array values are interpolated into double-quoted strings by joining all the
-elements of the array with the delimiter specified in the $" variable,
-space by default.
-(Since in versions of perl prior to 3.0 the @ character was not a metacharacter
-in double-quoted strings, the interpolation of @array, $array[EXPR],
-@array[LIST], $array{EXPR}, or @array{LIST} only happens if array is
-referenced elsewhere in the program or is predefined.)
-The following are equivalent:
-.nf
-
-.ne 4
-	$temp = join($",@ARGV);
-	system "echo $temp";
-
-	system "echo @ARGV";
-
-.fi
-Within search patterns (which also undergo double-quotish substitution)
-there is a bad ambiguity:  Is /$foo[bar]/ to be
-interpreted as /${foo}[bar]/ (where [bar] is a character class for the
-regular expression) or as /${foo[bar]}/ (where [bar] is the subscript to
-array @foo)?
-If @foo doesn't otherwise exist, then it's obviously a character class.
-If @foo exists, perl takes a good guess about [bar], and is almost always right.
-If it does guess wrong, or if you're just plain paranoid,
-you can force the correct interpretation with curly brackets as above.
-.PP
-A line-oriented form of quoting is based on the shell here-is syntax.
-Following a << you specify a string to terminate the quoted material, and all lines
-following the current line down to the terminating string are the value
-of the item.
-The terminating string may be either an identifier (a word), or some
-quoted text.
-If quoted, the type of quotes you use determines the treatment of the text,
-just as in regular quoting.
-An unquoted identifier works like double quotes.
-There must be no space between the << and the identifier.
-(If you put a space it will be treated as a null identifier, which is
-valid, and matches the first blank line\*(--see Merry Christmas example below.)
-The terminating string must appear by itself (unquoted and with no surrounding
-whitespace) on the terminating line.
-.nf
-
-	print <<EOF;		# same as above
-The price is $Price.
-EOF
-
-	print <<"EOF";		# same as above
-The price is $Price.
-EOF
-
-	print << x 10;		# null identifier is delimiter
-Merry Christmas!
-
-	print <<`EOC`;		# execute commands
-echo hi there
-echo lo there
-EOC
-
-	print <<foo, <<bar;	# you can stack them
-I said foo.
-foo
-I said bar.
-bar

-.fi
-Array literals are denoted by separating individual values by commas, and
-enclosing the list in parentheses:
-.nf
-
-	(LIST)
-
-.fi
-In a context not requiring an array value, the value of the array literal
-is the value of the final element, as in the C comma operator.
-For example,
-.nf
-
-.ne 4
-    @foo = (\'cc\', \'\-E\', $bar);
-
-assigns the entire array value to array foo, but
-
-    $foo = (\'cc\', \'\-E\', $bar);
-
-.fi
-assigns the value of variable bar to variable foo.
-Note that the value of an actual array in a scalar context is the length
-of the array; the following assigns to $foo the value 3:
-.nf
-
-.ne 2
-    @foo = (\'cc\', \'\-E\', $bar);
-    $foo = @foo;		# $foo gets 3
-
-.fi
-You may have an optional comma before the closing parenthesis of an
-array literal, so that you can say:
-.nf
-
-    @foo = (
-	1,
-	2,
-	3,
-    );
-
-.fi
-When a LIST is evaluated, each element of the list is evaluated in
-an array context, and the resulting array value is interpolated into LIST
-just as if each individual element were a member of LIST.  Thus arrays
-lose their identity in a LIST\*(--the list
-
-	(@foo,@bar,&SomeSub)
-
-contains all the elements of @foo followed by all the elements of @bar,
-followed by all the elements returned by the subroutine named SomeSub.
-.PP
-A list value may also be subscripted like a normal array.
-Examples:
-.nf
-
-	$time = (stat($file))[8];	# stat returns array value
-	$digit = ('a','b','c','d','e','f')[$digit-10];
-	return (pop(@foo),pop(@foo))[0];
-
-.fi
-.PP
-Array lists may be assigned to if and only if each element of the list
-is an lvalue:
-.nf
-
-    ($a, $b, $c) = (1, 2, 3);
-
-    ($map{\'red\'}, $map{\'blue\'}, $map{\'green\'}) = (0x00f, 0x0f0, 0xf00);
-
-The final element may be an array or an associative array:
-
-    ($a, $b, @rest) = split;
-    local($a, $b, %rest) = @_;
-
-.fi
-You can actually put an array anywhere in the list, but the first array
-in the list will soak up all the values, and anything after it will get
-a null value.
-This may be useful in a local().
-.PP
-An associative array literal contains pairs of values to be interpreted
-as a key and a value:
-.nf
-
-.ne 2
-    # same as map assignment above
-    %map = ('red',0x00f,'blue',0x0f0,'green',0xf00);
-
-.fi
-Array assignment in a scalar context returns the number of elements
-produced by the expression on the right side of the assignment:
-.nf
-
-	$x = (($foo,$bar) = (3,2,1));	# set $x to 3, not 2
-
-.fi
-.PP
-There are several other pseudo-literals that you should know about.
-If a string is enclosed by backticks (grave accents), it first undergoes
-variable substitution just like a double quoted string.
-It is then interpreted as a command, and the output of that command
-is the value of the pseudo-literal, like in a shell.
-In a scalar context, a single string consisting of all the output is
-returned.
-In an array context, an array of values is returned, one for each line
-of output.
-(You can set $/ to use a different line terminator.)
-The command is executed each time the pseudo-literal is evaluated.
-The status value of the command is returned in $? (see Predefined Names
-for the interpretation of $?).
-Unlike in \f2csh\f1, no translation is done on the return
-data\*(--newlines remain newlines.
-Unlike in any of the shells, single quotes do not hide variable names
-in the command from interpretation.
-To pass a $ through to the shell you need to hide it with a backslash.
-.PP
-Evaluating a filehandle in angle brackets yields the next line
-from that file (newline included, so it's never false until EOF, at
-which time an undefined value is returned).
-Ordinarily you must assign that value to a variable,
-but there is one situation where an automatic assignment happens.
-If (and only if) the input symbol is the only thing inside the conditional of a
-.I while
-loop, the value is
-automatically assigned to the variable \*(L"$_\*(R".
-(This may seem like an odd thing to you, but you'll use the construct
-in almost every
-.I perl
-script you write.)
-Anyway, the following lines are equivalent to each other:
-.nf
-
-.ne 5
-    while ($_ = <STDIN>) { print; }
-    while (<STDIN>) { print; }
-    for (\|;\|<STDIN>;\|) { print; }
-    print while $_ = <STDIN>;
-    print while <STDIN>;
-
-.fi
-The filehandles
-.IR STDIN ,
-.I STDOUT
-and
-.I STDERR
-are predefined.
-(The filehandles
-.IR stdin ,
-.I stdout
-and
-.I stderr
-will also work except in packages, where they would be interpreted as
-local identifiers rather than global.)
-Additional filehandles may be created with the
-.I open
-function.
-.PP
-If a <FILEHANDLE> is used in a context that is looking for an array, an array
-consisting of all the input lines is returned, one line per array element.
-It's easy to make a LARGE data space this way, so use with care.
-.PP
-The null filehandle <> is special and can be used to emulate the behavior of
-\fIsed\fR and \fIawk\fR.
-Input from <> comes either from standard input, or from each file listed on
-the command line.
-Here's how it works: the first time <> is evaluated, the ARGV array is checked,
-and if it is null, $ARGV[0] is set to \'-\', which when opened gives you standard
-input.
-The ARGV array is then processed as a list of filenames.
-The loop
-.nf
-
-.ne 3
-	while (<>) {
-		.\|.\|.			# code for each line
-	}
-
-.ne 10
-is equivalent to the following Perl-like pseudo code:
-
-	unshift(@ARGV, \'\-\') \|if \|$#ARGV < $[;
-	while ($ARGV = shift) {
-		open(ARGV, $ARGV);
-		while (<ARGV>) {
-			.\|.\|.		# code for each line
-		}
-	}
-
-.fi
-except that it isn't as cumbersome to say, and will actually work.
-It really does shift array ARGV and put the current filename into
-variable ARGV.
-It also uses filehandle ARGV internally\*(--<> is just a synonym for
-<ARGV>, which is magical.
-(The pseudo code above doesn't work because it treats <ARGV> as non-magical.)
-.PP
-You can modify @ARGV before the first <> as long as the array ends up
-containing the list of filenames you really want.
-Line numbers ($.) continue as if the input was one big happy file.
-(But see example under eof for how to reset line numbers on each file.)
-.PP
-.ne 5
-If you want to set @ARGV to your own list of files, go right ahead.
-If you want to pass switches into your script, you can
-put a loop on the front like this:
-.nf
-
-.ne 10
-	while ($_ = $ARGV[0], /\|^\-/\|) {
-		shift;
-	    last if /\|^\-\|\-$\|/\|;
-		/\|^\-D\|(.*\|)/ \|&& \|($debug = $1);
-		/\|^\-v\|/ \|&& \|$verbose++;
-		.\|.\|.		# other switches
-	}
-	while (<>) {
-		.\|.\|.		# code for each line
-	}
-
-.fi
-The <> symbol will return FALSE only once.
-If you call it again after this it will assume you are processing another
-@ARGV list, and if you haven't set @ARGV, will input from
-.IR STDIN .
-.PP
-If the string inside the angle brackets is a reference to a scalar variable
-(e.g. <$foo>),
-then that variable contains the name of the filehandle to input from.
-.PP
-If the string inside angle brackets is not a filehandle, it is interpreted
-as a filename pattern to be globbed, and either an array of filenames or the
-next filename in the list is returned, depending on context.
-One level of $ interpretation is done first, but you can't say <$foo>
-because that's an indirect filehandle as explained in the previous
-paragraph.
-You could insert curly brackets to force interpretation as a
-filename glob: <${foo}>.
-Example:
-.nf
-
-.ne 3
-	while (<*.c>) {
-		chmod 0644, $_;
-	}
-
-is equivalent to
-
-.ne 5
-	open(foo, "echo *.c | tr \-s \' \et\er\ef\' \'\e\e012\e\e012\e\e012\e\e012\'|");
-	while (<foo>) {
-		chop;
-		chmod 0644, $_;
-	}
-
-.fi
-In fact, it's currently implemented that way.
-(Which means it will not work on filenames with spaces in them unless
-you have /bin/csh on your machine.)
-Of course, the shortest way to do the above is:
-.nf
-
-	chmod 0644, <*.c>;
-
-.fi
-.Sh "Syntax"
-.PP
-A
-.I perl
-script consists of a sequence of declarations and commands.
-The only things that need to be declared in
-.I perl
-are report formats and subroutines.
-See the sections below for more information on those declarations.
-All uninitialized user-created objects are assumed to
-start with a null or 0 value until they
-are defined by some explicit operation such as assignment.
-The sequence of commands is executed just once, unlike in
-.I sed
-and
-.I awk
-scripts, where the sequence of commands is executed for each input line.
-While this means that you must explicitly loop over the lines of your input file
-(or files), it also means you have much more control over which files and which
-lines you look at.
-(Actually, I'm lying\*(--it is possible to do an implicit loop with either the
-.B \-n
-or
-.B \-p
-switch.)
-.PP
-A declaration can be put anywhere a command can, but has no effect on the
-execution of the primary sequence of commands\*(--declarations all take effect
-at compile time.
-Typically all the declarations are put at the beginning or the end of the script.
-.PP
-.I Perl
-is, for the most part, a free-form language.
-(The only exception to this is format declarations, for fairly obvious reasons.)
-Comments are indicated by the # character, and extend to the end of the line.
-If you attempt to use /* */ C comments, it will be interpreted either as
-division or pattern matching, depending on the context.
-So don't do that.
-.Sh "Compound statements"
-In
-.IR perl ,
-a sequence of commands may be treated as one command by enclosing it
-in curly brackets.
-We will call this a BLOCK.
-.PP
-The following compound commands may be used to control flow:
-.nf
-
-.ne 4
-	if (EXPR) BLOCK
-	if (EXPR) BLOCK else BLOCK
-	if (EXPR) BLOCK elsif (EXPR) BLOCK .\|.\|. else BLOCK
-	LABEL while (EXPR) BLOCK
-	LABEL while (EXPR) BLOCK continue BLOCK
-	LABEL for (EXPR; EXPR; EXPR) BLOCK
-	LABEL foreach VAR (ARRAY) BLOCK
-	LABEL BLOCK continue BLOCK
-
-.fi
-Note that, unlike C and Pascal, these are defined in terms of BLOCKs, not
-statements.
-This means that the curly brackets are \fIrequired\fR\*(--no dangling statements allowed.
-If you want to write conditionals without curly brackets there are several
-other ways to do it.
-The following all do the same thing:
-.nf
-
-.ne 5
-	if (!open(foo)) { die "Can't open $foo: $!"; }
-	die "Can't open $foo: $!" unless open(foo);
-	open(foo) || die "Can't open $foo: $!";	# foo or bust!
-	open(foo) ? \'hi mom\' : die "Can't open $foo: $!";
-				# a bit exotic, that last one
-
-.fi
-.PP
-The
-.I if
-statement is straightforward.
-Since BLOCKs are always bounded by curly brackets, there is never any
-ambiguity about which
-.I if
-an
-.I else
-goes with.
-If you use
-.I unless
-in place of
-.IR if ,
-the sense of the test is reversed.
-.PP
-The
-.I while
-statement executes the block as long as the expression is true
-(does not evaluate to the null string or 0).
-The LABEL is optional, and if present, consists of an identifier followed by
-a colon.
-The LABEL identifies the loop for the loop control statements
-.IR next ,
-.IR last ,
-and
-.I redo
-(see below).
-If there is a
-.I continue
-BLOCK, it is always executed just before
-the conditional is about to be evaluated again, similarly to the third part
-of a
-.I for
-loop in C.
-Thus it can be used to increment a loop variable, even when the loop has
-been continued via the
-.I next
-statement (similar to the C \*(L"continue\*(R" statement).
-.PP
-If the word
-.I while
-is replaced by the word
-.IR until ,
-the sense of the test is reversed, but the conditional is still tested before
-the first iteration.
-.PP
-In either the
-.I if
-or the
-.I while
-statement, you may replace \*(L"(EXPR)\*(R" with a BLOCK, and the conditional
-is true if the value of the last command in that block is true.
-.PP
-The
-.I for
-loop works exactly like the corresponding
-.I while
-loop:
-.nf
-
-.ne 12
-	for ($i = 1; $i < 10; $i++) {
-		.\|.\|.
-	}
-
-is the same as
-
-	$i = 1;
-	while ($i < 10) {
-		.\|.\|.
-	} continue {
-		$i++;
-	}
-.fi
-.PP
-The foreach loop iterates over a normal array value and sets the variable
-VAR to be each element of the array in turn.
-The variable is implicitly local to the loop, and regains its former value
-upon exiting the loop.
-The \*(L"foreach\*(R" keyword is actually identical to the \*(L"for\*(R" keyword,
-so you can use \*(L"foreach\*(R" for readability or \*(L"for\*(R" for brevity.
-If VAR is omitted, $_ is set to each value.
-If ARRAY is an actual array (as opposed to an expression returning an array
-value), you can modify each element of the array
-by modifying VAR inside the loop.
-Examples:
-.nf
-
-.ne 5
-	for (@ary) { s/foo/bar/; }
-
-	foreach $elem (@elements) {
-		$elem *= 2;
-	}
-
-.ne 3
-	for ((10,9,8,7,6,5,4,3,2,1,\'BOOM\')) {
-		print $_, "\en"; sleep(1);
-	}
-
-	for (1..15) { print "Merry Christmas\en"; }
-
-.ne 3
-	foreach $item (split(/:[\e\e\en:]*/, $ENV{\'TERMCAP\'})) {
-		print "Item: $item\en";
-	}
-
-.fi
-.PP
-The BLOCK by itself (labeled or not) is equivalent to a loop that executes
-once.
-Thus you can use any of the loop control statements in it to leave or
-restart the block.
-The
-.I continue
-block is optional.
-This construct is particularly nice for doing case structures.
-.nf
-
-.ne 6
-	foo: {
-		if (/^abc/) { $abc = 1; last foo; }
-		if (/^def/) { $def = 1; last foo; }
-		if (/^xyz/) { $xyz = 1; last foo; }
-		$nothing = 1;
-	}
-
-.fi
-There is no official switch statement in perl, because there
-are already several ways to write the equivalent.
-In addition to the above, you could write
-.nf
-
-.ne 6
-	foo: {
-		$abc = 1, last foo  if /^abc/;
-		$def = 1, last foo  if /^def/;
-		$xyz = 1, last foo  if /^xyz/;
-		$nothing = 1;
-	}
-
-or
-
-.ne 6
-	foo: {
-		/^abc/ && do { $abc = 1; last foo; };
-		/^def/ && do { $def = 1; last foo; };
-		/^xyz/ && do { $xyz = 1; last foo; };
-		$nothing = 1;
-	}
-
-or
-
-.ne 6
-	foo: {
-		/^abc/ && ($abc = 1, last foo);
-		/^def/ && ($def = 1, last foo);
-		/^xyz/ && ($xyz = 1, last foo);
-		$nothing = 1;
-	}
-
-or even
-
-.ne 8
-	if (/^abc/)
-		{ $abc = 1; }
-	elsif (/^def/)
-		{ $def = 1; }
-	elsif (/^xyz/)
-		{ $xyz = 1; }
-	else
-		{$nothing = 1;}
-
-.fi
-As it happens, these are all optimized internally to a switch structure,
-so perl jumps directly to the desired statement, and you needn't worry
-about perl executing a lot of unnecessary statements when you have a string
-of 50 elsifs, as long as you are testing the same simple scalar variable
-using ==, eq, or pattern matching as above.
-(If you're curious as to whether the optimizer has done this for a particular
-case statement, you can use the \-D1024 switch to list the syntax tree
-before execution.)
-.Sh "Simple statements"
-The only kind of simple statement is an expression evaluated for its side
-effects.
-Every simple statement must be terminated with a semicolon, unless it is the
-final statement in a block, in which case the semicolon is optional.
-(Semicolon is still encouraged there if the block takes up more than one line).

-Any simple statement may optionally be followed by a
-single modifier, just before the terminating semicolon.
-The possible modifiers are:
-.nf
-
-.ne 4
-	if EXPR
-	unless EXPR
-	while EXPR
-	until EXPR
-
-.fi
-The
-.I if
-and
-.I unless
-modifiers have the expected semantics.
-The
-.I while
-and
-.I until
-modifiers also have the expected semantics (conditional evaluated first),
-except when applied to a do-BLOCK or a do-SUBROUTINE command,
-in which case the block executes once before the conditional is evaluated.
-This is so that you can write loops like:
-.nf
-
-.ne 4
-	do {
-		$_ = <STDIN>;
-		.\|.\|.
-	} until $_ \|eq \|".\|\e\|n";
-
-.fi
-(See the
-.I do
-operator below.  Note also that the loop control commands described later will
-NOT work in this construct, since modifiers don't take loop labels.
-Sorry.)
-.Sh "Expressions"
-Since
-.I perl
-expressions work almost exactly like C expressions, only the differences
-will be mentioned here.
-.PP
-Here's what
-.I perl
-has that C doesn't:
-.Ip ** 8 2
-The exponentiation operator.
-.Ip **= 8
-The exponentiation assignment operator.
-.Ip (\|) 8 3
-The null list, used to initialize an array to null.
-.Ip . 8
-Concatenation of two strings.
-.Ip .= 8
-The concatenation assignment operator.
-.Ip eq 8
-String equality (== is numeric equality).
-For a mnemonic just think of \*(L"eq\*(R" as a string.
-(If you are used to the
-.I awk
-behavior of using == for either string or numeric equality
-based on the current form of the comparands, beware!
-You must be explicit here.)
-.Ip ne 8
-String inequality (!= is numeric inequality).
-.Ip lt 8
-String less than.
-.Ip gt 8
-String greater than.
-.Ip le 8
-String less than or equal.
-.Ip ge 8
-String greater than or equal.
-.Ip cmp 8
-String comparison, returning -1, 0, or 1.
-.Ip <=> 8
-Numeric comparison, returning -1, 0, or 1.
-.Ip =~ 8 2
-Certain operations search or modify the string \*(L"$_\*(R" by default.
-This operator makes that kind of operation work on some other string.
-The right argument is a search pattern, substitution, or translation.
-The left argument is what is supposed to be searched, substituted, or
-translated instead of the default \*(L"$_\*(R".
-The return value indicates the success of the operation.
-(If the right argument is an expression other than a search pattern,
-substitution, or translation, it is interpreted as a search pattern
-at run time.
-This is less efficient than an explicit search, since the pattern must
-be compiled every time the expression is evaluated.)
-The precedence of this operator is lower than unary minus and autoincrement/decrement, but higher than everything else.
-.Ip !~ 8
-Just like =~ except the return value is negated.
-.Ip x 8
-The repetition operator.
-Returns a string consisting of the left operand repeated the
-number of times specified by the right operand.
-In an array context, if the left operand is a list in parens, it repeats
-the list.
-.nf
-
-	print \'\-\' x 80;		# print row of dashes
-	print \'\-\' x80;		# illegal, x80 is identifier
-
-	print "\et" x ($tab/8), \' \' x ($tab%8);	# tab over
-
-	@ones = (1) x 80;		# an array of 80 1's
-	@ones = (5) x @ones;		# set all elements to 5
-
-.fi
-.Ip x= 8
-The repetition assignment operator.
-Only works on scalars.
-.Ip .\|. 8
-The range operator, which is really two different operators depending
-on the context.
-In an array context, returns an array of values counting (by ones)
-from the left value to the right value.
-This is useful for writing \*(L"for (1..10)\*(R" loops and for doing
-slice operations on arrays.
-.Sp
-In a scalar context, .\|. returns a boolean value.
-The operator is bistable, like a flip-flop, and
-emulates the line-range (comma) operator of sed, awk, and various editors.
-Each .\|. operator maintains its own boolean state.
-It is false as long as its left operand is false.
-Once the left operand is true, the range operator stays true
-until the right operand is true,
-AFTER which the range operator becomes false again.
-(It doesn't become false till the next time the range operator is evaluated.
-It can test the right operand and become false on the
-same evaluation it became true (as in awk), but it still returns true once.
-If you don't want it to test the right operand till the next
-evaluation (as in sed), use three dots (.\|.\|.) instead of two.)
-The right operand is not evaluated while the operator is in the \*(L"false\*(R" state,
-and the left operand is not evaluated while the operator is in the \*(L"true\*(R" state.
-The precedence is a little lower than || and &&.
-The value returned is either the null string for false, or a sequence number
-(beginning with 1) for true.
-The sequence number is reset for each range encountered.
-The final sequence number in a range has the string \'E0\' appended to it, which
-doesn't affect its numeric value, but gives you something to search for if you
-want to exclude the endpoint.
-You can exclude the beginning point by waiting for the sequence number to be
-greater than 1.
-If either operand of scalar .\|. is static, that operand is implicitly compared
-to the $. variable, the current line number.
-Examples:
-.nf
-
-.ne 6
-As a scalar operator:
-    if (101 .\|. 200) { print; }	# print 2nd hundred lines
-
-    next line if (1 .\|. /^$/);	# skip header lines
-
-    s/^/> / if (/^$/ .\|. eof());	# quote body
-
-.ne 4
-As an array operator:
-    for (101 .\|. 200) { print; }	# print $_ 100 times
-
-    @foo = @foo[$[ .\|. $#foo];	# an expensive no-op
-    @foo = @foo[$#foo-4 .\|. $#foo];	# slice last 5 items
-
-.fi
-.Ip \-x 8
-A file test.
-This unary operator takes one argument, either a filename or a filehandle,
-and tests the associated file to see if something is true about it.
-If the argument is omitted, tests $_, except for \-t, which tests
-.IR STDIN .
-It returns 1 for true and \'\' for false, or the undefined value if the
-file doesn't exist.
-Precedence is higher than logical and relational operators, but lower than
-arithmetic operators.
-The operator may be any of:
-.nf
-	\-r	File is readable by effective uid/gid.
-	\-w	File is writable by effective uid/gid.
-	\-x	File is executable by effective uid/gid.
-	\-o	File is owned by effective uid.
-	\-R	File is readable by real uid/gid.
-	\-W	File is writable by real uid/gid.
-	\-X	File is executable by real uid/gid.
-	\-O	File is owned by real uid.
-	\-e	File exists.
-	\-z	File has zero size.
-	\-s	File has non-zero size (returns size).
-	\-f	File is a plain file.
-	\-d	File is a directory.
-	\-l	File is a symbolic link.
-	\-p	File is a named pipe (FIFO).
-	\-S	File is a socket.
-	\-b	File is a block special file.
-	\-c	File is a character special file.
-	\-u	File has setuid bit set.
-	\-g	File has setgid bit set.
-	\-k	File has sticky bit set.
-	\-t	Filehandle is opened to a tty.
-	\-T	File is a text file.
-	\-B	File is a binary file (opposite of \-T).
-	\-M	Age of file in days when script started.
-	\-A	Same for access time.
-	\-C	Same for inode change time.
-
-.fi
-The interpretation of the file permission operators \-r, \-R, \-w, \-W, \-x and \-X
-is based solely on the mode of the file and the uids and gids of the user.
-There may be other reasons you can't actually read, write or execute the file.
-Also note that, for the superuser, \-r, \-R, \-w and \-W always return 1, and 
-\-x and \-X return 1 if any execute bit is set in the mode.
-Scripts run by the superuser may thus need to do a stat() in order to determine
-the actual mode of the file, or temporarily set the uid to something else.
-.Sp
-Example:
-.nf
-.ne 7
-	
-	while (<>) {
-		chop;
-		next unless \-f $_;	# ignore specials
-		.\|.\|.
-	}
-
-.fi
-Note that \-s/a/b/ does not do a negated substitution.
-Saying \-exp($foo) still works as expected, however\*(--only single letters
-following a minus are interpreted as file tests.
-.Sp
-The \-T and \-B switches work as follows.
-The first block or so of the file is examined for odd characters such as
-strange control codes or metacharacters.
-If too many odd characters (>10%) are found, it's a \-B file, otherwise it's a \-T file.
-Also, any file containing null in the first block is considered a binary file.
-If \-T or \-B is used on a filehandle, the current stdio buffer is examined
-rather than the first block.
-Both \-T and \-B return TRUE on a null file, or a file at EOF when testing
-a filehandle.
-.PP
-If any of the file tests (or either stat operator) are given the special
-filehandle consisting of a solitary underline, then the stat structure
-of the previous file test (or stat operator) is used, saving a system
-call.
-(This doesn't work with \-t, and you need to remember that lstat and -l
-will leave values in the stat structure for the symbolic link, not the
-real file.)
-Example:
-.nf
-
-	print "Can do.\en" if -r $a || -w _ || -x _;
-
-.ne 9
-	stat($filename);
-	print "Readable\en" if -r _;
-	print "Writable\en" if -w _;
-	print "Executable\en" if -x _;
-	print "Setuid\en" if -u _;
-	print "Setgid\en" if -g _;
-	print "Sticky\en" if -k _;
-	print "Text\en" if -T _;
-	print "Binary\en" if -B _;
-
-.fi
-.PP
-Here is what C has that
-.I perl
-doesn't:
-.Ip "unary &" 12
-Address-of operator.
-.Ip "unary *" 12
-Dereference-address operator.
-.Ip "(TYPE)" 12
-Type casting operator.
-.PP
-Like C,
-.I perl
-does a certain amount of expression evaluation at compile time, whenever
-it determines that all of the arguments to an operator are static and have
-no side effects.
-In particular, string concatenation happens at compile time between literals that don't do variable substitution.
-Backslash interpretation also happens at compile time.
-You can say
-.nf
-
-.ne 2
-	\'Now is the time for all\' . "\|\e\|n" .
-	\'good men to come to.\'
-
-.fi
-and this all reduces to one string internally.
-.PP
-The autoincrement operator has a little extra built-in magic to it.
-If you increment a variable that is numeric, or that has ever been used in
-a numeric context, you get a normal increment.
-If, however, the variable has only been used in string contexts since it
-was set, and has a value that is not null and matches the
-pattern /^[a\-zA\-Z]*[0\-9]*$/, the increment is done
-as a string, preserving each character within its range, with carry:
-.nf
-
-	print ++($foo = \'99\');	# prints \*(L'100\*(R'
-	print ++($foo = \'a0\');	# prints \*(L'a1\*(R'
-	print ++($foo = \'Az\');	# prints \*(L'Ba\*(R'
-	print ++($foo = \'zz\');	# prints \*(L'aaa\*(R'
-
-.fi
-The autodecrement is not magical.
-.PP
-The range operator (in an array context) makes use of the magical
-autoincrement algorithm if the minimum and maximum are strings.
-You can say
-
-	@alphabet = (\'A\' .. \'Z\');
-
-to get all the letters of the alphabet, or
-
-	$hexdigit = (0 .. 9, \'a\' .. \'f\')[$num & 15];
-
-to get a hexadecimal digit, or
-
-	@z2 = (\'01\' .. \'31\');  print @z2[$mday];
-
-to get dates with leading zeros.
-(If the final value specified is not in the sequence that the magical increment
-would produce, the sequence goes until the next value would be longer than
-the final value specified.)
-.PP
-The || and && operators differ from C's in that, rather than returning 0 or 1,
-they return the last value evaluated. 
-Thus, a portable way to find out the home directory might be:
-.nf
-
-	$home = $ENV{'HOME'} || $ENV{'LOGDIR'} ||
-	    (getpwuid($<))[7] || die "You're homeless!\en";
-
-.fi
-.PP
-Along with the literals and variables mentioned earlier,
-the operations in the following section can serve as terms in an expression.
-Some of these operations take a LIST as an argument.
-Such a list can consist of any combination of scalar arguments or array values;
-the array values will be included in the list as if each individual element were
-interpolated at that point in the list, forming a longer single-dimensional
-array value.
-Elements of the LIST should be separated by commas.
-If an operation is listed both with and without parentheses around its
-arguments, it means you can either use it as a unary operator or
-as a function call.
-To use it as a function call, the next token on the same line must
-be a left parenthesis.
-(There may be intervening white space.)
-Such a function then has highest precedence, as you would expect from
-a function.
-If any token other than a left parenthesis follows, then it is a
-unary operator, with a precedence depending only on whether it is a LIST
-operator or not.
-LIST operators have lowest precedence.
-All other unary operators have a precedence greater than relational operators
-but less than arithmetic operators.
-See the section on Precedence.
-.PP
-For operators that can be used in either a scalar or array context,
-failure is generally indicated in a scalar context by returning
-the undefined value, and in an array context by returning the null list.
-Remember though that
-THERE IS NO GENERAL RULE FOR CONVERTING A LIST INTO A SCALAR.
-Each operator decides which sort of scalar it would be most
-appropriate to return.
-Some operators return the length of the list
-that would have been returned in an array context.
-Some operators return the first value in the list.
-Some operators return the last value in the list.
-Some operators return a count of successful operations.
-In general, they do what you want, unless you want consistency.
-.Ip "/PATTERN/" 8 4
-See m/PATTERN/.
-.Ip "?PATTERN?" 8 4
-This is just like the /pattern/ search, except that it matches only once between
-calls to the
-.I reset
-operator.
-This is a useful optimization when you only want to see the first occurrence of
-something in each file of a set of files, for instance.
-Only ?? patterns local to the current package are reset.
-.Ip "accept(NEWSOCKET,GENERICSOCKET)" 8 2
-Does the same thing that the accept system call does.
-Returns true if it succeeded, false otherwise.
-See example in section on Interprocess Communication.
-.Ip "alarm(SECONDS)" 8 4
-.Ip "alarm SECONDS" 8
-Arranges to have a SIGALRM delivered to this process after the specified number
-of seconds (minus 1, actually) have elapsed.  Thus, alarm(15) will cause
-a SIGALRM at some point more than 14 seconds in the future.
-Only one timer may be counting at once.  Each call disables the previous
-timer, and an argument of 0 may be supplied to cancel the previous timer
-without starting a new one.
-The returned value is the amount of time remaining on the previous timer.
-.Ip "atan2(Y,X)" 8 2
-Returns the arctangent of Y/X in the range
-.if t \-\(*p to \(*p.
-.if n \-PI to PI.
-.Ip "bind(SOCKET,NAME)" 8 2
-Does the same thing that the bind system call does.
-Returns true if it succeeded, false otherwise.
-NAME should be a packed address of the proper type for the socket.
-See example in section on Interprocess Communication.
-.Ip "binmode(FILEHANDLE)" 8 4
-.Ip "binmode FILEHANDLE" 8 4
-Arranges for the file to be read in \*(L"binary\*(R" mode in operating systems
-that distinguish between binary and text files.
-Files that are not read in binary mode have CR LF sequences translated
-to LF on input and LF translated to CR LF on output.
-Binmode has no effect under Unix.
-If FILEHANDLE is an expression, the value is taken as the name of
-the filehandle.
-.Ip "caller(EXPR)"
-.Ip "caller"
-Returns the context of the current subroutine call:
-.nf
-
-	($package,$filename,$line) = caller;
-
-.fi
-With EXPR, returns some extra information that the debugger uses to print
-a stack trace.  The value of EXPR indicates how many call frames to go
-back before the current one.
-.Ip "chdir(EXPR)" 8 2
-.Ip "chdir EXPR" 8 2
-Changes the working directory to EXPR, if possible.
-If EXPR is omitted, changes to home directory.
-Returns 1 upon success, 0 otherwise.
-See example under
-.IR die .
-.Ip "chmod(LIST)" 8 2
-.Ip "chmod LIST" 8 2
-Changes the permissions of a list of files.
-The first element of the list must be the numerical mode.
-Returns the number of files successfully changed.
-.nf
-
-.ne 2
-	$cnt = chmod 0755, \'foo\', \'bar\';
-	chmod 0755, @executables;
-
-.fi
-.Ip "chop(LIST)" 8 7
-.Ip "chop(VARIABLE)" 8
-.Ip "chop VARIABLE" 8
-.Ip "chop" 8
-Chops off the last character of a string and returns the character chopped.
-It's used primarily to remove the newline from the end of an input record,
-but is much more efficient than s/\en// because it neither scans nor copies
-the string.
-If VARIABLE is omitted, chops $_.
-Example:
-.nf
-
-.ne 5
-	while (<>) {
-		chop;	# avoid \en on last field
-		@array = split(/:/);
-		.\|.\|.
-	}
-
-.fi
-You can actually chop anything that's an lvalue, including an assignment:
-.nf
-
-	chop($cwd = \`pwd\`);
-	chop($answer = <STDIN>);
-
-.fi
-If you chop a list, each element is chopped.
-Only the value of the last chop is returned.
-.Ip "chown(LIST)" 8 2
-.Ip "chown LIST" 8 2
-Changes the owner (and group) of a list of files.
-The first two elements of the list must be the NUMERICAL uid and gid,
-in that order.
-Returns the number of files successfully changed.
-.nf
-
-.ne 2
-	$cnt = chown $uid, $gid, \'foo\', \'bar\';
-	chown $uid, $gid, @filenames;
-
-.fi
-.ne 23
-Here's an example that looks up non-numeric uids in the passwd file:
-.nf
-
-	print "User: ";
-	$user = <STDIN>;
-	chop($user);
-	print "Files: "
-	$pattern = <STDIN>;
-	chop($pattern);
-.ie t \{\
-	open(pass, \'/etc/passwd\') || die "Can't open passwd: $!\en";
-'br\}
-.el \{\
-	open(pass, \'/etc/passwd\')
-		|| die "Can't open passwd: $!\en";
-'br\}
-	while (<pass>) {
-		($login,$pass,$uid,$gid) = split(/:/);
-		$uid{$login} = $uid;
-		$gid{$login} = $gid;
-	}
-	@ary = <${pattern}>;	# get filenames
-	if ($uid{$user} eq \'\') {
-		die "$user not in passwd file";
-	}
-	else {
-		chown $uid{$user}, $gid{$user}, @ary;
-	}
-
-.fi
-.Ip "chroot(FILENAME)" 8 5
-.Ip "chroot FILENAME" 8
-Does the same as the system call of that name.
-If you don't know what it does, don't worry about it.
-If FILENAME is omitted, does chroot to $_.
-.Ip "close(FILEHANDLE)" 8 5
-.Ip "close FILEHANDLE" 8
-Closes the file or pipe associated with the file handle.
-You don't have to close FILEHANDLE if you are immediately going to
-do another open on it, since open will close it for you.
-(See
-.IR open .)
-However, an explicit close on an input file resets the line counter ($.), while
-the implicit close done by
-.I open
-does not.
-Also, closing a pipe will wait for the process executing on the pipe to complete,
-in case you want to look at the output of the pipe afterwards.
-Closing a pipe explicitly also puts the status value of the command into $?.
-Example:
-.nf
-
-.ne 4
-	open(OUTPUT, \'|sort >foo\');	# pipe to sort
-	.\|.\|.	# print stuff to output
-	close OUTPUT;		# wait for sort to finish
-	open(INPUT, \'foo\');	# get sort's results
-
-.fi
-FILEHANDLE may be an expression whose value gives the real filehandle name.
-.Ip "closedir(DIRHANDLE)" 8 5
-.Ip "closedir DIRHANDLE" 8
-Closes a directory opened by opendir().
-.Ip "connect(SOCKET,NAME)" 8 2
-Does the same thing that the connect system call does.
-Returns true if it succeeded, false otherwise.
-NAME should be a package address of the proper type for the socket.
-See example in section on Interprocess Communication.
-.Ip "cos(EXPR)" 8 6
-.Ip "cos EXPR" 8 6
-Returns the cosine of EXPR (expressed in radians).
-If EXPR is omitted takes cosine of $_.
-.Ip "crypt(PLAINTEXT,SALT)" 8 6
-Encrypts a string exactly like the crypt() function in the C library.
-Useful for checking the password file for lousy passwords.
-Only the guys wearing white hats should do this.
-.Ip "dbmclose(ASSOC_ARRAY)" 8 6
-.Ip "dbmclose ASSOC_ARRAY" 8
-Breaks the binding between a dbm file and an associative array.
-The values remaining in the associative array are meaningless unless
-you happen to want to know what was in the cache for the dbm file.
-This function is only useful if you have ndbm.
-.Ip "dbmopen(ASSOC,DBNAME,MODE)" 8 6
-This binds a dbm or ndbm file to an associative array.
-ASSOC is the name of the associative array.
-(Unlike normal open, the first argument is NOT a filehandle, even though
-it looks like one).
-DBNAME is the name of the database (without the .dir or .pag extension).
-If the database does not exist, it is created with protection specified
-by MODE (as modified by the umask).
-If your system only supports the older dbm functions, you may perform only one
-dbmopen in your program.
-If your system has neither dbm nor ndbm, calling dbmopen produces a fatal
-error.
-.Sp
-Values assigned to the associative array prior to the dbmopen are lost.
-A certain number of values from the dbm file are cached in memory.
-By default this number is 64, but you can increase it by preallocating
-that number of garbage entries in the associative array before the dbmopen.
-You can flush the cache if necessary with the reset command.
-.Sp
-If you don't have write access to the dbm file, you can only read
-associative array variables, not set them.
-If you want to test whether you can write, either use file tests or
-try setting a dummy array entry inside an eval, which will trap the error.
-.Sp
-Note that functions such as keys() and values() may return huge array values
-when used on large dbm files.
-You may prefer to use the each() function to iterate over large dbm files.
-Example:
-.nf
-
-.ne 6
-	# print out history file offsets
-	dbmopen(HIST,'/usr/lib/news/history',0666);
-	while (($key,$val) = each %HIST) {
-		print $key, ' = ', unpack('L',$val), "\en";
-	}
-	dbmclose(HIST);
-
-.fi
-.Ip "defined(EXPR)" 8 6
-.Ip "defined EXPR" 8
-Returns a boolean value saying whether the lvalue EXPR has a real value
-or not.
-Many operations return the undefined value under exceptional conditions,
-such as end of file, uninitialized variable, system error and such.
-This function allows you to distinguish between an undefined null string
-and a defined null string with operations that might return a real null
-string, in particular referencing elements of an array.
-You may also check to see if arrays or subroutines exist.
-Use on predefined variables is not guaranteed to produce intuitive results.
-Examples:
-.nf
-
-.ne 7
-	print if defined $switch{'D'};
-	print "$val\en" while defined($val = pop(@ary));
-	die "Can't readlink $sym: $!"
-		unless defined($value = readlink $sym);
-	eval '@foo = ()' if defined(@foo);
-	die "No XYZ package defined" unless defined %_XYZ;
-	sub foo { defined &$bar ? &$bar(@_) : die "No bar"; }
-
-.fi
-See also undef.
-.Ip "delete $ASSOC{KEY}" 8 6
-Deletes the specified value from the specified associative array.
-Returns the deleted value, or the undefined value if nothing was deleted.
-Deleting from $ENV{} modifies the environment.
-Deleting from an array bound to a dbm file deletes the entry from the dbm
-file.
-.Sp
-The following deletes all the values of an associative array:
-.nf
-
-.ne 3
-	foreach $key (keys %ARRAY) {
-		delete $ARRAY{$key};
-	}
-
-.fi
-(But it would be faster to use the
-.I reset
-command.
-Saying undef %ARRAY is faster yet.)
-.Ip "die(LIST)" 8
-.Ip "die LIST" 8
-Outside of an eval, prints the value of LIST to
-.I STDERR
-and exits with the current value of $!
-(errno).
-If $! is 0, exits with the value of ($? >> 8) (\`command\` status).
-If ($? >> 8) is 0, exits with 255.
-Inside an eval, the error message is stuffed into $@ and the eval is terminated
-with the undefined value.
-.Sp
-Equivalent examples:
-.nf
-
-.ne 3
-.ie t \{\
-	die "Can't cd to spool: $!\en" unless chdir \'/usr/spool/news\';
-'br\}
-.el \{\
-	die "Can't cd to spool: $!\en"
-		unless chdir \'/usr/spool/news\';
-'br\}
-
-	chdir \'/usr/spool/news\' || die "Can't cd to spool: $!\en" 
-
-.fi
-.Sp
-If the value of EXPR does not end in a newline, the current script line
-number and input line number (if any) are also printed, and a newline is
-supplied.
-Hint: sometimes appending \*(L", stopped\*(R" to your message will cause it to make
-better sense when the string \*(L"at foo line 123\*(R" is appended.
-Suppose you are running script \*(L"canasta\*(R".

-.IR exit .
-.Ip "do BLOCK" 8 4
-Returns the value of the last command in the sequence of commands indicated
-by BLOCK.
-When modified by a loop modifier, executes the BLOCK once before testing the
-loop condition.
-(On other statements the loop modifiers test the conditional first.)
-.Ip "do SUBROUTINE (LIST)" 8 3
-Executes a SUBROUTINE declared by a
-.I sub
-declaration, and returns the value
-of the last expression evaluated in SUBROUTINE.
-If there is no subroutine by that name, produces a fatal error.
-(You may use the \*(L"defined\*(R" operator to determine if a subroutine
-exists.)
-If you pass arrays as part of LIST you may wish to pass the length
-of the array in front of each array.
-(See the section on subroutines later on.)
-The parentheses are required to avoid confusion with the \*(L"do EXPR\*(R"
-form.
-.Sp
-SUBROUTINE may also be a single scalar variable, in which case
-the name of the subroutine to execute is taken from the variable.
-.Sp
-As an alternate (and preferred) form,
-you may call a subroutine by prefixing the name with
-an ampersand: &foo(@args).
-If you aren't passing any arguments, you don't have to use parentheses.
-If you omit the parentheses, no @_ array is passed to the subroutine.
-The & form is also used to specify subroutines to the defined and undef
-operators:
-.nf
-
-	if (defined &$var) { &$var($parm); undef &$var; }
-
-.fi
-.Ip "do EXPR" 8 3
-Uses the value of EXPR as a filename and executes the contents of the file
-as a
-.I perl
-script.
-Its primary use is to include subroutines from a
-.I perl
-subroutine library.
-.nf
-
-	do \'stat.pl\';
-
-is just like
-
-	eval \`cat stat.pl\`;
-
-.fi
-except that it's more efficient, more concise, keeps track of the current
-filename for error messages, and searches all the
-.B \-I
-libraries if the file
-isn't in the current directory (see also the @INC array in Predefined Names).
-It's the same, however, in that it does reparse the file every time you
-call it, so if you are going to use the file inside a loop you might prefer
-to use \-P and #include, at the expense of a little more startup time.
-(The main problem with #include is that cpp doesn't grok # comments\*(--a
-workaround is to use \*(L";#\*(R" for standalone comments.)
-Note that the following are NOT equivalent:
-.nf
-
-.ne 2
-	do $foo;	# eval a file
-	do $foo();	# call a subroutine
-
-.fi
-Note that inclusion of library routines is better done with
-the \*(L"require\*(R" operator.
-.Ip "dump LABEL" 8 6
-This causes an immediate core dump.
-Primarily this is so that you can use the undump program to turn your
-core dump into an executable binary after having initialized all your
-variables at the beginning of the program.
-When the new binary is executed it will begin by executing a "goto LABEL"
-(with all the restrictions that goto suffers).
-Think of it as a goto with an intervening core dump and reincarnation.
-If LABEL is omitted, restarts the program from the top.
-WARNING: any files opened at the time of the dump will NOT be open any more
-when the program is reincarnated, with possible resulting confusion on the part
-of perl.
-See also \-u.
-.Sp
-Example:
-.nf
-
-.ne 16
-	#!/usr/bin/perl
-	require 'getopt.pl';
-	require 'stat.pl';
-	%days = (
-	    'Sun',1,
-	    'Mon',2,
-	    'Tue',3,
-	    'Wed',4,
-	    'Thu',5,
-	    'Fri',6,
-	    'Sat',7);
-
-	dump QUICKSTART if $ARGV[0] eq '-d';
-
-    QUICKSTART:
-	do Getopt('f');
-
-.fi
-.Ip "each(ASSOC_ARRAY)" 8 6
-.Ip "each ASSOC_ARRAY" 8
-Returns a 2 element array consisting of the key and value for the next
-value of an associative array, so that you can iterate over it.
-Entries are returned in an apparently random order.
-When the array is entirely read, a null array is returned (which when
-assigned produces a FALSE (0) value).
-The next call to each() after that will start iterating again.
-The iterator can be reset only by reading all the elements from the array.
-You must not modify the array while iterating over it.
-There is a single iterator for each associative array, shared by all
-each(), keys() and values() function calls in the program.
-The following prints out your environment like the printenv program, only
-in a different order:
-.nf
-
-.ne 3
-	while (($key,$value) = each %ENV) {
-		print "$key=$value\en";
-	}
-
-.fi
-See also keys() and values().
-.Ip "eof(FILEHANDLE)" 8 8
-.Ip "eof()" 8
-.Ip "eof" 8
-Returns 1 if the next read on FILEHANDLE will return end of file, or if
-FILEHANDLE is not open.
-FILEHANDLE may be an expression whose value gives the real filehandle name.
-(Note that this function actually reads a character and then ungetc's it,
-so it is not very useful in an interactive context.)
-An eof without an argument returns the eof status for the last file read.
-Empty parentheses () may be used to indicate the pseudo file formed of the
-files listed on the command line, i.e. eof() is reasonable to use inside
-a while (<>) loop to detect the end of only the last file.
-Use eof(ARGV) or eof without the parentheses to test EACH file in a while (<>) loop.
-Examples:
-.nf
-
-.ne 7
-	# insert dashes just before last line of last file
-	while (<>) {
-		if (eof()) {
-			print "\-\|\-\|\-\|\-\|\-\|\-\|\-\|\-\|\-\|\-\|\-\|\-\|\-\|\-\en";
-		}
-		print;
-	}
-
-.ne 7
-	# reset line numbering on each input file
-	while (<>) {
-		print "$.\et$_";
-		if (eof) {	# Not eof().
-			close(ARGV);
-		}
-	}
-
-.fi
-.Ip "eval(EXPR)" 8 6
-.Ip "eval EXPR" 8 6
-.Ip "eval BLOCK" 8 6
-EXPR is parsed and executed as if it were a little
-.I perl
-program.
-It is executed in the context of the current
-.I perl
-program, so that
-any variable settings, subroutine or format definitions remain afterwards.
-The value returned is the value of the last expression evaluated, just
-as with subroutines.
-If there is a syntax error or runtime error, or a die statement is
-executed, an undefined value is returned by
-eval, and $@ is set to the error message.
-If there was no error, $@ is guaranteed to be a null string.
-If EXPR is omitted, evaluates $_.
-The final semicolon, if any, may be omitted from the expression.
-.Sp
-Note that, since eval traps otherwise-fatal errors, it is useful for
-determining whether a particular feature
-(such as dbmopen or symlink) is implemented.
-It is also Perl's exception trapping mechanism, where the die operator is
-used to raise exceptions.
-.Sp
-If the code to be executed doesn't vary, you may use
-the eval-BLOCK form to trap run-time errors without incurring
-the penalty of recompiling each time.
-The error, if any, is still returned in $@.
-Evaluating a single-quoted string (as EXPR) has the same effect, except that
-the eval-EXPR form reports syntax errors at run time via $@, whereas the
-eval-BLOCK form reports syntax errors at compile time.  The eval-EXPR form
-is optimized to eval-BLOCK the first time it succeeds.  (Since the replacement
-side of a substitution is considered a single-quoted string when you
-use the e modifier, the same optimization occurs there.)  Examples:
-.nf
-
-.ne 11
-	# make divide-by-zero non-fatal
-	eval { $answer = $a / $b; }; warn $@ if $@;
-
-	# optimized to same thing after first use
-	eval '$answer = $a / $b'; warn $@ if $@;
-
-	# a compile-time error
-	eval { $answer = };
-
-	# a run-time error
-	eval '$answer =';	# sets $@
-
-.fi
-.Ip "exec(LIST)" 8 8
-.Ip "exec LIST" 8 6
-If there is more than one argument in LIST, or if LIST is an array with
-more than one value,
-calls execvp() with the arguments in LIST.
-If there is only one scalar argument, the argument is checked for shell metacharacters.
-If there are any, the entire argument is passed to \*(L"/bin/sh \-c\*(R" for parsing.
-If there are none, the argument is split into words and passed directly to
-execvp(), which is more efficient.
-Note: exec (and system) do not flush your output buffer, so you may need to
-set $| to avoid lost output.
-Examples:
-.nf
-
-	exec \'/bin/echo\', \'Your arguments are: \', @ARGV;
-	exec "sort $outfile | uniq";
-
-.fi
-.Sp
-If you don't really want to execute the first argument, but want to lie
-to the program you are executing about its own name, you can specify
-the program you actually want to run by assigning that to a variable and
-putting the name of the variable in front of the LIST without a comma.
-(This always forces interpretation of the LIST as a multi-valued list, even
-if there is only a single scalar in the list.)
-Example:
-.nf
-
-.ne 2
-	$shell = '/bin/csh';
-	exec $shell '-sh';		# pretend it's a login shell
-
-.fi
-.Ip "exit(EXPR)" 8 6
-.Ip "exit EXPR" 8
-Evaluates EXPR and exits immediately with that value.
-Example:
-.nf
-
-.ne 2
-	$ans = <STDIN>;
-	exit 0 \|if \|$ans \|=~ \|/\|^[Xx]\|/\|;
-
-.fi
-See also
-.IR die .
-If EXPR is omitted, exits with 0 status.
-.Ip "exp(EXPR)" 8 3
-.Ip "exp EXPR" 8
-Returns
-.I e
-to the power of EXPR.
-If EXPR is omitted, gives exp($_).
-.Ip "fcntl(FILEHANDLE,FUNCTION,SCALAR)" 8 4
-Implements the fcntl(2) function.
-You'll probably have to say
-.nf
-
-	require "fcntl.ph";	# probably /usr/local/lib/perl/fcntl.ph
-
-.fi
-first to get the correct function definitions.
-If fcntl.ph doesn't exist or doesn't have the correct definitions
-you'll have to roll
-your own, based on your C header files such as <sys/fcntl.h>.
-(There is a perl script called h2ph that comes with the perl kit
-which may help you in this.)
-Argument processing and value return works just like ioctl below.
-Note that fcntl will produce a fatal error if used on a machine that doesn't implement
-fcntl(2).
-.Ip "fileno(FILEHANDLE)" 8 4
-.Ip "fileno FILEHANDLE" 8 4
-Returns the file descriptor for a filehandle.
-Useful for constructing bitmaps for select().
-If FILEHANDLE is an expression, the value is taken as the name of
-the filehandle.
-.Ip "flock(FILEHANDLE,OPERATION)" 8 4
-Calls flock(2) on FILEHANDLE.
-See manual page for flock(2) for definition of OPERATION.
-Returns true for success, false on failure.
-Will produce a fatal error if used on a machine that doesn't implement
-flock(2).
-Here's a mailbox appender for BSD systems.
-.nf
-
-.ne 20
-	$LOCK_SH = 1;
-	$LOCK_EX = 2;
-	$LOCK_NB = 4;
-	$LOCK_UN = 8;
-
-	sub lock {
-	    flock(MBOX,$LOCK_EX);
-	    # and, in case someone appended
-	    # while we were waiting...
-	    seek(MBOX, 0, 2);

-
-	do lock();
-	print MBOX $msg,"\en\en";
-	do unlock();
-
-.fi
-.Ip "fork" 8 4
-Does a fork() call.
-Returns the child pid to the parent process and 0 to the child process.
-Note: unflushed buffers remain unflushed in both processes, which means
-you may need to set $| to avoid duplicate output.
-.Ip "getc(FILEHANDLE)" 8 4
-.Ip "getc FILEHANDLE" 8
-.Ip "getc" 8
-Returns the next character from the input file attached to FILEHANDLE, or
-a null string at EOF.
-If FILEHANDLE is omitted, reads from STDIN.
-.Ip "getlogin" 8 3
-Returns the current login from /etc/utmp, if any.
-If null, use getpwuid.
-
-	$login = getlogin || (getpwuid($<))[0] || "Somebody";
-
-.Ip "getpeername(SOCKET)" 8 3
-Returns the packed sockaddr address of other end of the SOCKET connection.
-.nf
-
-.ne 4
-	# An internet sockaddr
-	$sockaddr = 'S n a4 x8';
-	$hersockaddr = getpeername(S);

-'br\}
-
-.fi
-.Ip "getpgrp(PID)" 8 4
-.Ip "getpgrp PID" 8
-Returns the current process group for the specified PID, 0 for the current
-process.
-Will produce a fatal error if used on a machine that doesn't implement
-getpgrp(2).
-If EXPR is omitted, returns process group of current process.
-.Ip "getppid" 8 4
-Returns the process id of the parent process.
-.Ip "getpriority(WHICH,WHO)" 8 4
-Returns the current priority for a process, a process group, or a user.
-(See getpriority(2).)
-Will produce a fatal error if used on a machine that doesn't implement
-getpriority(2).
-.Ip "getpwnam(NAME)" 8

-.Ip "endservent" 8
-These routines perform the same functions as their counterparts in the
-system library.
-Within an array context,
-the return values from the various get routines are as follows:
-.nf
-
-	($name,$passwd,$uid,$gid,
-	   $quota,$comment,$gcos,$dir,$shell) = getpw.\|.\|.
-	($name,$passwd,$gid,$members) = getgr.\|.\|.
-	($name,$aliases,$addrtype,$length,@addrs) = gethost.\|.\|.
-	($name,$aliases,$addrtype,$net) = getnet.\|.\|.
-	($name,$aliases,$proto) = getproto.\|.\|.
-	($name,$aliases,$port,$proto) = getserv.\|.\|.
-
-.fi
-(If the entry doesn't exist you get a null list.)
-.Sp
-Within a scalar context, you get the name, unless the function was a
-lookup by name, in which case you get the other thing, whatever it is.
-(If the entry doesn't exist you get the undefined value.)
-For example:
-.nf
-
-	$uid = getpwnam
-	$name = getpwuid
-	$name = getpwent
-	$gid = getgrnam
-	$name = getgrgid
-	$name = getgrent
-	etc.
-
-.fi
-The $members value returned by getgr.\|.\|. is a space separated list
-of the login names of the members of the group.
-.Sp
-For the gethost.\|.\|. functions, if the h_errno variable is supported in C,
-it will be returned to you via $? if the function call fails.
-The @addrs value returned by a successful call is a list of the
-raw addresses returned by the corresponding system library call.
-In the Internet domain, each address is four bytes long and you can unpack
-it by saying something like:
-.nf
-
-	($a,$b,$c,$d) = unpack('C4',$addr[0]);
-
-.fi
-.Ip "getsockname(SOCKET)" 8 3
-Returns the packed sockaddr address of this end of the SOCKET connection.
-.nf
-
-.ne 4
-	# An internet sockaddr
-	$sockaddr = 'S n a4 x8';
-	$mysockaddr = getsockname(S);
-.ie t \{\
-	($family, $port, $myaddr) = unpack($sockaddr,$mysockaddr);
-'br\}
-.el \{\
-	($family, $port, $myaddr) =
-			unpack($sockaddr,$mysockaddr);
-'br\}
-
-.fi
-.Ip "getsockopt(SOCKET,LEVEL,OPTNAME)" 8 3
-Returns the socket option requested, or undefined if there is an error.
-.Ip "gmtime(EXPR)" 8 4
-.Ip "gmtime EXPR" 8
-Converts a time as returned by the time function to a 9-element array with
-the time analyzed for the Greenwich timezone.
-Typically used as follows:
-.nf
-
-.ne 3
-.ie t \{\
-    ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = gmtime(time);
-'br\}
-.el \{\
-    ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) =
-						gmtime(time);
-'br\}
-
-.fi
-All array elements are numeric, and come straight out of a struct tm.
-In particular this means that $mon has the range 0.\|.11 and $wday has the
-range 0.\|.6.
-If EXPR is omitted, does gmtime(time).
-.Ip "goto LABEL" 8 6
-Finds the statement labeled with LABEL and resumes execution there.
-Currently you may only go to statements in the main body of the program
-that are not nested inside a do {} construct.
-This statement is not implemented very efficiently, and is here only to make
-the
-.IR sed -to- perl
-translator easier.
-I may change its semantics at any time, consistent with support for translated
-.I sed
-scripts.
-Use it at your own risk.
-Better yet, don't use it at all.
-.Ip "grep(EXPR,LIST)" 8 4
-Evaluates EXPR for each element of LIST (locally setting $_ to each element)
-and returns the array value consisting of those elements for which the
-expression evaluated to true.
-In a scalar context, returns the number of times the expression was true.
-.nf
-
-	@foo = grep(!/^#/, @bar);    # weed out comments
-
-.fi
-Note that, since $_ is a reference into the array value, it can be
-used to modify the elements of the array.
-While this is useful and supported, it can cause bizarre results if
-the LIST is not a named array.
-.Ip "hex(EXPR)" 8 4
-.Ip "hex EXPR" 8
-Returns the decimal value of EXPR interpreted as an hex string.
-(To interpret strings that might start with 0 or 0x see oct().)
-If EXPR is omitted, uses $_.
-.Ip "index(STR,SUBSTR,POSITION)" 8 4
-.Ip "index(STR,SUBSTR)" 8 4
-Returns the position of the first occurrence of SUBSTR in STR at or after
-POSITION.
-If POSITION is omitted, starts searching from the beginning of the string.
-The return value is based at 0, or whatever you've
-set the $[ variable to.
-If the substring is not found, returns one less than the base, ordinarily \-1.
-.Ip "int(EXPR)" 8 4
-.Ip "int EXPR" 8
-Returns the integer portion of EXPR.
-If EXPR is omitted, uses $_.
-.Ip "ioctl(FILEHANDLE,FUNCTION,SCALAR)" 8 4
-Implements the ioctl(2) function.
-You'll probably have to say
-.nf
-
-	require "ioctl.ph";	# probably /usr/local/lib/perl/ioctl.ph
-
-.fi
-first to get the correct function definitions.
-If ioctl.ph doesn't exist or doesn't have the correct definitions
-you'll have to roll
-your own, based on your C header files such as <sys/ioctl.h>.
-(There is a perl script called h2ph that comes with the perl kit
-which may help you in this.)
-SCALAR will be read and/or written depending on the FUNCTION\*(--a pointer
-to the string value of SCALAR will be passed as the third argument of
-the actual ioctl call.
-(If SCALAR has no string value but does have a numeric value, that value
-will be passed rather than a pointer to the string value.
-To guarantee this to be true, add a 0 to the scalar before using it.)
-The pack() and unpack() functions are useful for manipulating the values
-of structures used by ioctl().
-The following example sets the erase character to DEL.
-.nf
-
-.ne 9
-	require 'ioctl.ph';
-	$sgttyb_t = "ccccs";		# 4 chars and a short
-	if (ioctl(STDIN,$TIOCGETP,$sgttyb)) {
-		@ary = unpack($sgttyb_t,$sgttyb);
-		$ary[2] = 127;
-		$sgttyb = pack($sgttyb_t,@ary);
-		ioctl(STDIN,$TIOCSETP,$sgttyb)
-			|| die "Can't ioctl: $!";
-	}
-
-.fi
-The return value of ioctl (and fcntl) is as follows:
-.nf
-
-.ne 4
-	if OS returns:\h'|3i'perl returns:
-	  -1\h'|3i'  undefined value
-	  0\h'|3i'  string "0 but true"
-	  anything else\h'|3i'  that number
-
-.fi
-Thus perl returns true on success and false on failure, yet you can still
-easily determine the actual value returned by the operating system:
-.nf
-
-	($retval = ioctl(...)) || ($retval = -1);
-	printf "System returned %d\en", $retval;
-.fi
-.Ip "join(EXPR,LIST)" 8 8
-.Ip "join(EXPR,ARRAY)" 8
-Joins the separate strings of LIST or ARRAY into a single string with fields
-separated by the value of EXPR, and returns the string.
-Example:
-.nf
-    
-.ie t \{\
-    $_ = join(\|\':\', $login,$passwd,$uid,$gid,$gcos,$home,$shell);
-'br\}
-.el \{\
-    $_ = join(\|\':\',
-		$login,$passwd,$uid,$gid,$gcos,$home,$shell);
-'br\}
-
-.fi
-See
-.IR split .
-.Ip "keys(ASSOC_ARRAY)" 8 6
-.Ip "keys ASSOC_ARRAY" 8
-Returns a normal array consisting of all the keys of the named associative
-array.
-The keys are returned in an apparently random order, but it is the same order
-as either the values() or each() function produces (given that the associative array
-has not been modified).
-Here is yet another way to print your environment:
-.nf
-
-.ne 5
-	@keys = keys %ENV;
-	@values = values %ENV;
-	while ($#keys >= 0) {
-		print pop(@keys), \'=\', pop(@values), "\en";
-	}
-
-or how about sorted by key:
-
-.ne 3
-	foreach $key (sort(keys %ENV)) {
-		print $key, \'=\', $ENV{$key}, "\en";
-	}
-
-.fi
-.Ip "kill(LIST)" 8 8
-.Ip "kill LIST" 8 2
-Sends a signal to a list of processes.
-The first element of the list must be the signal to send.
-Returns the number of processes successfully signaled.
-.nf
-
-	$cnt = kill 1, $child1, $child2;
-	kill 9, @goners;
-
-.fi
-If the signal is negative, kills process groups instead of processes.
-(On System V, a negative \fIprocess\fR number will also kill process groups,
-but that's not portable.)
-You may use a signal name in quotes.
-.Ip "last LABEL" 8 8
-.Ip "last" 8
-The
-.I last
-command is like the
-.I break
-statement in C (as used in loops); it immediately exits the loop in question.
-If the LABEL is omitted, the command refers to the innermost enclosing loop.
-The
-.I continue
-block, if any, is not executed:
-.nf
-
-.ne 4
-	line: while (<STDIN>) {
-		last line if /\|^$/;	# exit when done with header
-		.\|.\|.
-	}
-
-.fi
-.Ip "length(EXPR)" 8 4
-.Ip "length EXPR" 8
-Returns the length in characters of the value of EXPR.
-If EXPR is omitted, returns length of $_.
-.Ip "link(OLDFILE,NEWFILE)" 8 2
-Creates a new filename linked to the old filename.
-Returns 1 for success, 0 otherwise.
-.Ip "listen(SOCKET,QUEUESIZE)" 8 2
-Does the same thing that the listen system call does.
-Returns true if it succeeded, false otherwise.
-See example in section on Interprocess Communication.
-.Ip "local(LIST)" 8 4
-Declares the listed variables to be local to the enclosing block,
-subroutine, eval or \*(L"do\*(R".
-All the listed elements must be legal lvalues.
-This operator works by saving the current values of those variables in LIST
-on a hidden stack and restoring them upon exiting the block, subroutine or eval.
-This means that called subroutines can also reference the local variable,
-but not the global one.
-The LIST may be assigned to if desired, which allows you to initialize
-your local variables.
-(If no initializer is given for a particular variable, it is created with
-an undefined value.)
-Commonly this is used to name the parameters to a subroutine.
-Examples:
-.nf
-
-.ne 13
-	sub RANGEVAL {
-		local($min, $max, $thunk) = @_;
-		local($result) = \'\';
-		local($i);
-
-		# Presumably $thunk makes reference to $i
-
-		for ($i = $min; $i < $max; $i++) {
-			$result .= eval $thunk;
-		}
-
-		$result;
-	}
-
-.ne 6
-	if ($sw eq \'-v\') {

-		do parse_num();
-	}
-
-.fi
-Note that local() is a run-time command, and so gets executed every time
-through a loop, using up more stack storage each time until it's all
-released at once when the loop is exited.
-.Ip "localtime(EXPR)" 8 4
-.Ip "localtime EXPR" 8
-Converts a time as returned by the time function to a 9-element array with
-the time analyzed for the local timezone.
-Typically used as follows:
-.nf
-
-.ne 3
-.ie t \{\
-    ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = localtime(time);
-'br\}
-.el \{\
-    ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) =
-						localtime(time);
-'br\}
-
-.fi
-All array elements are numeric, and come straight out of a struct tm.
-In particular this means that $mon has the range 0.\|.11 and $wday has the
-range 0.\|.6.
-If EXPR is omitted, does localtime(time).
-.Ip "log(EXPR)" 8 4
-.Ip "log EXPR" 8
-Returns logarithm (base
-.IR e )
-of EXPR.
-If EXPR is omitted, returns log of $_.
-.Ip "lstat(FILEHANDLE)" 8 6
-.Ip "lstat FILEHANDLE" 8
-.Ip "lstat(EXPR)" 8
-.Ip "lstat SCALARVARIABLE" 8
-Does the same thing as the stat() function, but stats a symbolic link
-instead of the file the symbolic link points to.
-If symbolic links are unimplemented on your system, a normal stat is done.
-.Ip "m/PATTERN/gio" 8 4
-.Ip "/PATTERN/gio" 8
-Searches a string for a pattern match, and returns true (1) or false (\'\').
-If no string is specified via the =~ or !~ operator,
-the $_ string is searched.
-(The string specified with =~ need not be an lvalue\*(--it may be the result of an expression evaluation, but remember the =~ binds rather tightly.)
-See also the section on regular expressions.
-.Sp
-If / is the delimiter then the initial \*(L'm\*(R' is optional.
-With the \*(L'm\*(R' you can use any pair of non-alphanumeric characters
-as delimiters.
-This is particularly useful for matching Unix path names that contain \*(L'/\*(R'.
-If the final delimiter is followed by the optional letter \*(L'i\*(R', the matching is
-done in a case-insensitive manner.
-PATTERN may contain references to scalar variables, which will be interpolated
-(and the pattern recompiled) every time the pattern search is evaluated.
-(Note that $) and $| may not be interpolated because they look like end-of-string tests.)
-If you want such a pattern to be compiled only once, add an \*(L"o\*(R" after
-the trailing delimiter.
-This avoids expensive run-time recompilations, and
-is useful when the value you are interpolating won't change over the
-life of the script.
-If the PATTERN evaluates to a null string, the most recent successful
-regular expression is used instead.
-.Sp
-If used in a context that requires an array value, a pattern match returns an
-array consisting of the subexpressions matched by the parentheses in the
-pattern,
-i.e. ($1, $2, $3.\|.\|.).
-It does NOT actually set $1, $2, etc. in this case, nor does it set $+, $`, $&
-or $'.
-If the match fails, a null array is returned.
-If the match succeeds, but there were no parentheses, an array value of (1)
-is returned.
-.Sp
-Examples:
-.nf
-
-.ne 4
-    open(tty, \'/dev/tty\');
-    <tty> \|=~ \|/\|^y\|/i \|&& \|do foo(\|);	# do foo if desired
-
-    if (/Version: \|*\|([0\-9.]*\|)\|/\|) { $version = $1; }
-
-    next if m#^/usr/spool/uucp#;
-
-.ne 5
-    # poor man's grep
-    $arg = shift;
-    while (<>) {
-	    print if /$arg/o;	# compile only once
-    }
-
-    if (($F1, $F2, $Etc) = ($foo =~ /^(\eS+)\es+(\eS+)\es*(.*)/))
-
-.fi
-This last example splits $foo into the first two words and the remainder
-of the line, and assigns those three fields to $F1, $F2 and $Etc.
-The conditional is true if any variables were assigned, i.e. if the pattern
-matched.
-.Sp
-The \*(L"g\*(R" modifier specifies global pattern matching\*(--that is,
-matching as many times as possible within the string.  How it behaves
-depends on the context.  In an array context, it returns a list of
-all the substrings matched by all the parentheses in the regular expression.
-If there are no parentheses, it returns a list of all the matched strings,
-as if there were parentheses around the whole pattern.  In a scalar context,
-it iterates through the string, returning TRUE each time it matches, and
-FALSE when it eventually runs out of matches.  (In other words, it remembers
-where it left off last time and restarts the search at that point.)  It
-presumes that you have not modified the string since the last match.
-Modifying the string between matches may result in undefined behavior.
-(You can actually get away with in-place modifications via substr()
-that do not change the length of the entire string.  In general, however,
-you should be using s///g for such modifications.)  Examples:
-.nf
-
-	# array context
-	($one,$five,$fifteen) = (\`uptime\` =~ /(\ed+\e.\ed+)/g);
-
-	# scalar context
-	$/ = ""; $* = 1;
-	while ($paragraph = <>) {
-	    while ($paragraph =~ /[a-z][\'")]*[.!?]+[\'")]*\es/g) {
-		$sentences++;
-	    }
-	}
-	print "$sentences\en";
-
-.fi
-.Ip "mkdir(FILENAME,MODE)" 8 3
-Creates the directory specified by FILENAME, with permissions specified by
-MODE (as modified by umask).
-If it succeeds it returns 1, otherwise it returns 0 and sets $! (errno).
-.Ip "msgctl(ID,CMD,ARG)" 8 4
-Calls the System V IPC function msgctl.  If CMD is &IPC_STAT, then ARG
-must be a variable which will hold the returned msqid_ds structure.
-Returns like ioctl: the undefined value for error, "0 but true" for
-zero, or the actual return value otherwise.
-.Ip "msgget(KEY,FLAGS)" 8 4
-Calls the System V IPC function msgget.  Returns the message queue id,
-or the undefined value if there is an error.
-.Ip "msgsnd(ID,MSG,FLAGS)" 8 4
-Calls the System V IPC function msgsnd to send the message MSG to the
-message queue ID.  MSG must begin with the long integer message type,
-which may be created with pack("L", $type).  Returns true if
-successful, or false if there is an error.
-.Ip "msgrcv(ID,VAR,SIZE,TYPE,FLAGS)" 8 4
-Calls the System V IPC function msgrcv to receive a message from
-message queue ID into variable VAR with a maximum message size of
-SIZE.  Note that if a message is received, the message type will be
-the first thing in VAR, and the maximum length of VAR is SIZE plus the
-size of the message type.  Returns true if successful, or false if
-there is an error.
-.Ip "next LABEL" 8 8
-.Ip "next" 8
-The
-.I next
-command is like the
-.I continue
-statement in C; it starts the next iteration of the loop:
-.nf
-
-.ne 4
-	line: while (<STDIN>) {
-		next line if /\|^#/;	# discard comments
-		.\|.\|.
-	}
-
-.fi
-Note that if there were a
-.I continue
-block on the above, it would get executed even on discarded lines.
-If the LABEL is omitted, the command refers to the innermost enclosing loop.
-.Ip "oct(EXPR)" 8 4
-.Ip "oct EXPR" 8
-Returns the decimal value of EXPR interpreted as an octal string.
-(If EXPR happens to start off with 0x, interprets it as a hex string instead.)
-The following will handle decimal, octal and hex in the standard notation:
-.nf
-
-	$val = oct($val) if $val =~ /^0/;
-
-.fi
-If EXPR is omitted, uses $_.
-.Ip "open(FILEHANDLE,EXPR)" 8 8
-.Ip "open(FILEHANDLE)" 8
-.Ip "open FILEHANDLE" 8
-Opens the file whose filename is given by EXPR, and associates it with
-FILEHANDLE.
-If FILEHANDLE is an expression, its value is used as the name of the
-real filehandle wanted.
-If EXPR is omitted, the scalar variable of the same name as the FILEHANDLE
-contains the filename.
-If the filename begins with \*(L"<\*(R" or nothing, the file is opened for
-input.
-If the filename begins with \*(L">\*(R", the file is opened for output.
-If the filename begins with \*(L">>\*(R", the file is opened for appending.
-(You can put a \'+\' in front of the \'>\' or \'<\' to indicate that you
-want both read and write access to the file.)
-If the filename begins with \*(L"|\*(R", the filename is interpreted
-as a command to which output is to be piped, and if the filename ends
-with a \*(L"|\*(R", the filename is interpreted as command which pipes
-input to us.
-(You may not have a command that pipes both in and out.)
-Opening \'\-\' opens
-.I STDIN
-and opening \'>\-\' opens
-.IR STDOUT .
-Open returns non-zero upon success, the undefined value otherwise.
-If the open involved a pipe, the return value happens to be the pid
-of the subprocess.
-Examples:
-.nf
-    
-.ne 3
-	$article = 100;
-	open article || die "Can't find article $article: $!\en";
-	while (<article>) {\|.\|.\|.

-.el \{\
-	open(LOG, \'>>/usr/spool/news/twitlog\'\|);
-					# (log is reserved)
-'br\}
-
-.ie t \{\
-	open(article, "caesar <$article |"\|);		# decrypt article
-'br\}
-.el \{\

-'br\}
-.el \{\

-
-.ne 7
-	# process argument list of files along with any includes

-	foreach $file (@ARGV) {
-		do process($file, \'fh00\');	# no pun intended
-	}
-
-	sub process {
-		local($filename, $input) = @_;
-		$input++;		# this is a string increment
-		unless (open($input, $filename)) {
-			print STDERR "Can't open $filename: $!\en";
-			return;
-		}
-.ie t \{\
-		while (<$input>) {		# note the use of indirection

-				do process($1, $input);
-				next;
-			}
-			.\|.\|.		# whatever
-		}
-	}
-
-.fi
-You may also, in the Bourne shell tradition, specify an EXPR beginning
-with \*(L">&\*(R", in which case the rest of the string
-is interpreted as the name of a filehandle
-(or file descriptor, if numeric) which is to be duped and opened.
-You may use & after >, >>, <, +>, +>> and +<.
-The mode you specify should match the mode of the original filehandle.
-Here is a script that saves, redirects, and restores
-.I STDOUT
-and
-.IR STDERR :
-.nf
-
-.ne 21
-	#!/usr/bin/perl
-	open(SAVEOUT, ">&STDOUT");
-	open(SAVEERR, ">&STDERR");
-
-	open(STDOUT, ">foo.out") || die "Can't redirect stdout";
-	open(STDERR, ">&STDOUT") || die "Can't dup stdout";
-
-	select(STDERR); $| = 1;		# make unbuffered
-	select(STDOUT); $| = 1;		# make unbuffered
-
-	print STDOUT "stdout 1\en";	# this works for
-	print STDERR "stderr 1\en"; 	# subprocesses too
-
-	close(STDOUT);
-	close(STDERR);
-
-	open(STDOUT, ">&SAVEOUT");
-	open(STDERR, ">&SAVEERR");
-
-	print STDOUT "stdout 2\en";
-	print STDERR "stderr 2\en";
-
-.fi
-If you open a pipe on the command \*(L"\-\*(R", i.e. either \*(L"|\-\*(R" or \*(L"\-|\*(R",
-then there is an implicit fork done, and the return value of open
-is the pid of the child within the parent process, and 0 within the child
-process.
-(Use defined($pid) to determine if the open was successful.)
-The filehandle behaves normally for the parent, but i/o to that
-filehandle is piped from/to the
-.IR STDOUT / STDIN
-of the child process.
-In the child process the filehandle isn't opened\*(--i/o happens from/to
-the new
-.I STDOUT
-or
-.IR STDIN .
-Typically this is used like the normal piped open when you want to exercise
-more control over just how the pipe command gets executed, such as when
-you are running setuid, and don't want to have to scan shell commands
-for metacharacters.
-The following pairs are more or less equivalent:
-.nf
-
-.ne 5
-	open(FOO, "|tr \'[a\-z]\' \'[A\-Z]\'");
-	open(FOO, "|\-") || exec \'tr\', \'[a\-z]\', \'[A\-Z]\';
-
-	open(FOO, "cat \-n '$file'|");
-	open(FOO, "\-|") || exec \'cat\', \'\-n\', $file;
-
-.fi
-Explicitly closing any piped filehandle causes the parent process to wait for the
-child to finish, and returns the status value in $?.
-Note: on any operation which may do a fork,
-unflushed buffers remain unflushed in both
-processes, which means you may need to set $| to
-avoid duplicate output.
-.Sp
-The filename that is passed to open will have leading and trailing
-whitespace deleted.
-In order to open a file with arbitrary weird characters in it, it's necessary
-to protect any leading and trailing whitespace thusly:
-.nf
-
-.ne 2
-        $file =~ s#^(\es)#./$1#;
-        open(FOO, "< $file\e0");
-
-.fi
-.Ip "opendir(DIRHANDLE,EXPR)" 8 3
-Opens a directory named EXPR for processing by readdir(), telldir(), seekdir(),
-rewinddir() and closedir().
-Returns true if successful.
-DIRHANDLEs have their own namespace separate from FILEHANDLEs.
-.Ip "ord(EXPR)" 8 4
-.Ip "ord EXPR" 8
-Returns the numeric ascii value of the first character of EXPR.
-If EXPR is omitted, uses $_.
-''' Comments on f & d by gnb@melba.bby.oz.au	22/11/89
-.Ip "pack(TEMPLATE,LIST)" 8 4
-Takes an array or list of values and packs it into a binary structure,
-returning the string containing the structure.
-The TEMPLATE is a sequence of characters that give the order and type
-of values, as follows:
-.nf
-
-	A	An ascii string, will be space padded.
-	a	An ascii string, will be null padded.
-	c	A signed char value.
-	C	An unsigned char value.
-	s	A signed short value.
-	S	An unsigned short value.
-	i	A signed integer value.
-	I	An unsigned integer value.
-	l	A signed long value.
-	L	An unsigned long value.
-	n	A short in \*(L"network\*(R" order.
-	N	A long in \*(L"network\*(R" order.
-	f	A single-precision float in the native format.
-	d	A double-precision float in the native format.
-	p	A pointer to a string.
-	v	A short in \*(L"VAX\*(R" (little-endian) order.
-	V	A long in \*(L"VAX\*(R" (little-endian) order.
-	x	A null byte.
-	X	Back up a byte.
-	@	Null fill to absolute position.
-	u	A uuencoded string.
-	b	A bit string (ascending bit order, like vec()).
-	B	A bit string (descending bit order).
-	h	A hex string (low nybble first).
-	H	A hex string (high nybble first).
-
-.fi
-Each letter may optionally be followed by a number which gives a repeat
-count.
-With all types except "a", "A", "b", "B", "h" and "H",
-the pack function will gobble up that many values
-from the LIST.
-A * for the repeat count means to use however many items are left.
-The "a" and "A" types gobble just one value, but pack it as a string of length
-count,
-padding with nulls or spaces as necessary.
-(When unpacking, "A" strips trailing spaces and nulls, but "a" does not.)
-Likewise, the "b" and "B" fields pack a string that many bits long.
-The "h" and "H" fields pack a string that many nybbles long.
-Real numbers (floats and doubles) are in the native machine format
-only; due to the multiplicity of floating formats around, and the lack
-of a standard \*(L"network\*(R" representation, no facility for
-interchange has been made.
-This means that packed floating point data
-written on one machine may not be readable on another - even if both
-use IEEE floating point arithmetic (as the endian-ness of the memory
-representation is not part of the IEEE spec).
-Note that perl uses
-doubles internally for all numeric calculation, and converting from
-double -> float -> double will lose precision (i.e. unpack("f",
-pack("f", $foo)) will not in general equal $foo).
-.br
-Examples:
-.nf
-
-	$foo = pack("cccc",65,66,67,68);
-	# foo eq "ABCD"
-	$foo = pack("c4",65,66,67,68);
-	# same thing
-
-	$foo = pack("ccxxcc",65,66,67,68);
-	# foo eq "AB\e0\e0CD"
-
-	$foo = pack("s2",1,2);
-	# "\e1\e0\e2\e0" on little-endian
-	# "\e0\e1\e0\e2" on big-endian
-
-	$foo = pack("a4","abcd","x","y","z");
-	# "abcd"
-
-	$foo = pack("aaaa","abcd","x","y","z");
-	# "axyz"
-
-	$foo = pack("a14","abcdefg");
-	# "abcdefg\e0\e0\e0\e0\e0\e0\e0"
-
-	$foo = pack("i9pl", gmtime);
-	# a real struct tm (on my system anyway)
-
-	sub bintodec {
-	    unpack("N", pack("B32", substr("0" x 32 . shift, -32)));
-	}
-.fi
-The same template may generally also be used in the unpack function.
-.Ip "pipe(READHANDLE,WRITEHANDLE)" 8 3
-Opens a pair of connected pipes like the corresponding system call.
-Note that if you set up a loop of piped processes, deadlock can occur
-unless you are very careful.
-In addition, note that perl's pipes use stdio buffering, so you may need
-to set $| to flush your WRITEHANDLE after each command, depending on
-the application.
-[Requires version 3.0 patchlevel 9.]
-.Ip "pop(ARRAY)" 8
-.Ip "pop ARRAY" 8 6
-Pops and returns the last value of the array, shortening the array by 1.
-Has the same effect as
-.nf
-
-	$tmp = $ARRAY[$#ARRAY\-\|\-];
-
-.fi
-If there are no elements in the array, returns the undefined value.
-.Ip "print(FILEHANDLE LIST)" 8 10
-.Ip "print(LIST)" 8
-.Ip "print FILEHANDLE LIST" 8
-.Ip "print LIST" 8
-.Ip "print" 8
-Prints a string or a comma-separated list of strings.
-Returns non-zero if successful.
-FILEHANDLE may be a scalar variable name, in which case the variable contains
-the name of the filehandle, thus introducing one level of indirection.
-(NOTE: If FILEHANDLE is a variable and the next token is a term, it may be
-misinterpreted as an operator unless you interpose a + or put parens around
-the arguments.)
-If FILEHANDLE is omitted, prints by default to standard output (or to the
-last selected output channel\*(--see select()).
-If LIST is also omitted, prints $_ to
-.IR STDOUT .
-To set the default output channel to something other than
-.I STDOUT
-use the select operation.
-Note that, because print takes a LIST, anything in the LIST is evaluated
-in an array context, and any subroutine that you call will have one or more
-of its expressions evaluated in an array context.
-Also be careful not to follow the print keyword with a left parenthesis
-unless you want the corresponding right parenthesis to terminate the
-arguments to the print\*(--interpose a + or put parens around all the arguments.
-.Ip "printf(FILEHANDLE LIST)" 8 10
-.Ip "printf(LIST)" 8
-.Ip "printf FILEHANDLE LIST" 8
-.Ip "printf LIST" 8
-Equivalent to a \*(L"print FILEHANDLE sprintf(LIST)\*(R".
-.Ip "push(ARRAY,LIST)" 8 7
-Treats ARRAY (@ is optional) as a stack, and pushes the values of LIST
-onto the end of ARRAY.
-The length of ARRAY increases by the length of LIST.
-Has the same effect as
-.nf
-
-    for $value (LIST) {
-	    $ARRAY[++$#ARRAY] = $value;
-    }
-
-.fi
-but is more efficient.
-.Ip "q/STRING/" 8 5
-.Ip "qq/STRING/" 8
-.Ip "qx/STRING/" 8
-These are not really functions, but simply syntactic sugar to let you
-avoid putting too many backslashes into quoted strings.
-The q operator is a generalized single quote, and the qq operator a
-generalized double quote.
-The qx operator is a generalized backquote.
-Any non-alphanumeric delimiter can be used in place of /, including newline.
-If the delimiter is an opening bracket or parenthesis, the final delimiter
-will be the corresponding closing bracket or parenthesis.
-(Embedded occurrences of the closing bracket need to be backslashed as usual.)
-Examples:
-.nf
-
-.ne 5
-	$foo = q!I said, "You said, \'She said it.\'"!;
-	$bar = q(\'This is it.\');
-	$today = qx{ date };
-	$_ .= qq
-*** The previous line contains the naughty word "$&".\en
-		if /(ibm|apple|awk)/;      # :-)
-
-.fi
-.Ip "rand(EXPR)" 8 8
-.Ip "rand EXPR" 8
-.Ip "rand" 8
-Returns a random fractional number between 0 and the value of EXPR.
-(EXPR should be positive.)
-If EXPR is omitted, returns a value between 0 and 1.
-See also srand().
-.Ip "read(FILEHANDLE,SCALAR,LENGTH,OFFSET)" 8 5
-.Ip "read(FILEHANDLE,SCALAR,LENGTH)" 8 5
-Attempts to read LENGTH bytes of data into variable SCALAR from the specified
-FILEHANDLE.
-Returns the number of bytes actually read, or undef if there was an error.
-SCALAR will be grown or shrunk to the length actually read.
-An OFFSET may be specified to place the read data at some other place
-than the beginning of the string.
-This call is actually implemented in terms of stdio's fread call.  To get
-a true read system call, see sysread.
-.Ip "readdir(DIRHANDLE)" 8 3
-.Ip "readdir DIRHANDLE" 8
-Returns the next directory entry for a directory opened by opendir().
-If used in an array context, returns all the rest of the entries in the
-directory.
-If there are no more entries, returns an undefined value in a scalar context
-or a null list in an array context.
-.Ip "readlink(EXPR)" 8 6
-.Ip "readlink EXPR" 8
-Returns the value of a symbolic link, if symbolic links are implemented.
-If not, gives a fatal error.
-If there is some system error, returns the undefined value and sets $! (errno).
-If EXPR is omitted, uses $_.
-.Ip "recv(SOCKET,SCALAR,LEN,FLAGS)" 8 4
-Receives a message on a socket.
-Attempts to receive LENGTH bytes of data into variable SCALAR from the specified
-SOCKET filehandle.
-Returns the address of the sender, or the undefined value if there's an error.
-SCALAR will be grown or shrunk to the length actually read.
-Takes the same flags as the system call of the same name.
-.Ip "redo LABEL" 8 8
-.Ip "redo" 8
-The
-.I redo
-command restarts the loop block without evaluating the conditional again.
-The
-.I continue
-block, if any, is not executed.
-If the LABEL is omitted, the command refers to the innermost enclosing loop.
-This command is normally used by programs that want to lie to themselves
-about what was just input:
-.nf
-
-.ne 16
-	# a simpleminded Pascal comment stripper
-	# (warning: assumes no { or } in strings)
-	line: while (<STDIN>) {
-		while (s|\|({.*}.*\|){.*}|$1 \||) {}
-		s|{.*}| \||;
-		if (s|{.*| \||) {
-			$front = $_;
-			while (<STDIN>) {
-				if (\|/\|}/\|) {	# end of comment?
-					s|^|$front{|;
-					redo line;
-				}
-			}
-		}
-		print;
-	}
-
-.fi
-.Ip "rename(OLDNAME,NEWNAME)" 8 2
-Changes the name of a file.
-Returns 1 for success, 0 otherwise.
-Will not work across filesystem boundaries.
-.Ip "require(EXPR)" 8 6
-.Ip "require EXPR" 8
-.Ip "require" 8
-Includes the library file specified by EXPR, or by $_ if EXPR is not supplied.
-Has semantics similar to the following subroutine:
-.nf
-
-	sub require {
-	    local($filename) = @_;
-	    return 1 if $INC{$filename};
-	    local($realfilename,$result);
-	    ITER: {
-		foreach $prefix (@INC) {
-		    $realfilename = "$prefix/$filename";
-		    if (-f $realfilename) {

-			last ITER;
-		    }
-		}
-		die "Can't find $filename in \e@INC";
-	    }
-	    die $@ if $@;
-	    die "$filename did not return true value" unless $result;
-	    $INC{$filename} = $realfilename;
-	    $result;
-	}
-
-.fi
-Note that the file will not be included twice under the same specified name.
-The file must return true as the last statement to indicate successful
-execution of any initialization code, so it's customary to end
-such a file with \*(L"1;\*(R" unless you're sure it'll return true otherwise.
-.Ip "reset(EXPR)" 8 6
-.Ip "reset EXPR" 8
-.Ip "reset" 8
-Generally used in a
-.I continue
-block at the end of a loop to clear variables and reset ?? searches
-so that they work again.
-The expression is interpreted as a list of single characters (hyphens allowed
-for ranges).
-All variables and arrays beginning with one of those letters are reset to
-their pristine state.
-If the expression is omitted, one-match searches (?pattern?) are reset to
-match again.
-Only resets variables or searches in the current package.
-Always returns 1.
-Examples:
-.nf
-
-.ne 3
-    reset \'X\';	\h'|2i'# reset all X variables
-    reset \'a\-z\';\h'|2i'# reset lower case variables
-    reset;	\h'|2i'# just reset ?? searches
-
-.fi
-Note: resetting \*(L"A\-Z\*(R" is not recommended since you'll wipe out your ARGV and ENV
-arrays.
-.Sp
-The use of reset on dbm associative arrays does not change the dbm file.
-(It does, however, flush any entries cached by perl, which may be useful if
-you are sharing the dbm file.
-Then again, maybe not.)
-.Ip "return LIST" 8 3
-Returns from a subroutine with the value specified.
-(Note that a subroutine can automatically return
-the value of the last expression evaluated.
-That's the preferred method\*(--use of an explicit
-.I return
-is a bit slower.)
-.Ip "reverse(LIST)" 8 4
-.Ip "reverse LIST" 8
-In an array context, returns an array value consisting of the elements
-of LIST in the opposite order.
-In a scalar context, returns a string value consisting of the bytes of
-the first element of LIST in the opposite order.
-.Ip "rewinddir(DIRHANDLE)" 8 5
-.Ip "rewinddir DIRHANDLE" 8
-Sets the current position to the beginning of the directory for the readdir() routine on DIRHANDLE.
-.Ip "rindex(STR,SUBSTR,POSITION)" 8 6
-.Ip "rindex(STR,SUBSTR)" 8 4
-Works just like index except that it
-returns the position of the LAST occurrence of SUBSTR in STR.
-If POSITION is specified, returns the last occurrence at or before that
-position.
-.Ip "rmdir(FILENAME)" 8 4
-.Ip "rmdir FILENAME" 8
-Deletes the directory specified by FILENAME if it is empty.
-If it succeeds it returns 1, otherwise it returns 0 and sets $! (errno).
-If FILENAME is omitted, uses $_.
-.Ip "s/PATTERN/REPLACEMENT/gieo" 8 3
-Searches a string for a pattern, and if found, replaces that pattern with the
-replacement text and returns the number of substitutions made.
-Otherwise it returns false (0).
-The \*(L"g\*(R" is optional, and if present, indicates that all occurrences
-of the pattern are to be replaced.
-The \*(L"i\*(R" is also optional, and if present, indicates that matching
-is to be done in a case-insensitive manner.
-The \*(L"e\*(R" is likewise optional, and if present, indicates that
-the replacement string is to be evaluated as an expression rather than just
-as a double-quoted string.
-Any non-alphanumeric delimiter may replace the slashes;
-if single quotes are used, no
-interpretation is done on the replacement string (the e modifier overrides
-this, however); if backquotes are used, the replacement string is a command
-to execute whose output will be used as the actual replacement text.
-If the PATTERN is delimited by bracketing quotes, the REPLACEMENT
-has its own pair of quotes, which may or may not be bracketing quotes, e.g.
-s(foo)(bar) or s<foo>/bar/.
-If no string is specified via the =~ or !~ operator,
-the $_ string is searched and modified.
-(The string specified with =~ must be a scalar variable, an array element,
-or an assignment to one of those, i.e. an lvalue.)
-If the pattern contains a $ that looks like a variable rather than an
-end-of-string test, the variable will be interpolated into the pattern at
-run-time.
-If you only want the pattern compiled once the first time the variable is
-interpolated, add an \*(L"o\*(R" at the end.
-If the PATTERN evaluates to a null string, the most recent successful
-regular expression is used instead.
-See also the section on regular expressions.
-Examples:
-.nf
-
-    s/\|\e\|bgreen\e\|b/mauve/g;		# don't change wintergreen
-
-    $path \|=~ \|s|\|/usr/bin|\|/usr/local/bin|;
-
-    s/Login: $foo/Login: $bar/; # run-time pattern
-
-    ($foo = $bar) =~ s/bar/foo/;
-
-    $_ = \'abc123xyz\';
-    s/\ed+/$&*2/e;		# yields \*(L'abc246xyz\*(R'
-    s/\ed+/sprintf("%5d",$&)/e;	# yields \*(L'abc  246xyz\*(R'
-    s/\ew/$& x 2/eg;		# yields \*(L'aabbcc  224466xxyyzz\*(R'
-
-    s/\|([^ \|]*\|) *\|([^ \|]*\|)\|/\|$2 $1/;	# reverse 1st two fields
-
-.fi
-(Note the use of $ instead of \|\e\| in the last example.  See section
-on regular expressions.)
-.Ip "scalar(EXPR)" 8 3
-Forces EXPR to be interpreted in a scalar context and returns the value
-of EXPR.
-.Ip "seek(FILEHANDLE,POSITION,WHENCE)" 8 3
-Randomly positions the file pointer for FILEHANDLE, just like the fseek()
-call of stdio.
-FILEHANDLE may be an expression whose value gives the name of the filehandle.
-Returns 1 upon success, 0 otherwise.
-.Ip "seekdir(DIRHANDLE,POS)" 8 3
-Sets the current position for the readdir() routine on DIRHANDLE.
-POS must be a value returned by telldir().
-Has the same caveats about possible directory compaction as the corresponding
-system library routine.
-.Ip "select(FILEHANDLE)" 8 3
-.Ip "select" 8 3
-Returns the currently selected filehandle.
-Sets the current default filehandle for output, if FILEHANDLE is supplied.
-This has two effects: first, a
-.I write
-or a
-.I print
-without a filehandle will default to this FILEHANDLE.
-Second, references to variables related to output will refer to this output
-channel.
-For example, if you have to set the top of form format for more than
-one output channel, you might do the following:
-.nf
-
-.ne 4
-	select(REPORT1);
-	$^ = \'report1_top\';
-	select(REPORT2);
-	$^ = \'report2_top\';
-
-.fi
-FILEHANDLE may be an expression whose value gives the name of the actual filehandle.
-Thus:
-.nf
-
-	$oldfh = select(STDERR); $| = 1; select($oldfh);
-
-.fi
-.Ip "select(RBITS,WBITS,EBITS,TIMEOUT)" 8 3
-This calls the select system call with the bitmasks specified, which can
-be constructed using fileno() and vec(), along these lines:
-.nf
-
-	$rin = $win = $ein = '';
-	vec($rin,fileno(STDIN),1) = 1;
-	vec($win,fileno(STDOUT),1) = 1;
-	$ein = $rin | $win;
-
-.fi
-If you want to select on many filehandles you might wish to write a subroutine:
-.nf
-
-	sub fhbits {
-	    local(@fhlist) = split(' ',$_[0]);
-	    local($bits);
-	    for (@fhlist) {
-		vec($bits,fileno($_),1) = 1;
-	    }
-	    $bits;
-	}
-	$rin = &fhbits('STDIN TTY SOCK');
-
-.fi
-The usual idiom is:
-.nf
-
-	($nfound,$timeleft) =
-	  select($rout=$rin, $wout=$win, $eout=$ein, $timeout);
-
-or to block until something becomes ready:
-
-.ie t \{\
-	$nfound = select($rout=$rin, $wout=$win, $eout=$ein, undef);
-'br\}
-.el \{\
-	$nfound = select($rout=$rin, $wout=$win,
-				$eout=$ein, undef);
-'br\}
-
-.fi
-Any of the bitmasks can also be undef.
-The timeout, if specified, is in seconds, which may be fractional.
-NOTE: not all implementations are capable of returning the $timeleft.
-If not, they always return $timeleft equal to the supplied $timeout.
-.Ip "semctl(ID,SEMNUM,CMD,ARG)" 8 4
-Calls the System V IPC function semctl.  If CMD is &IPC_STAT or
-&GETALL, then ARG must be a variable which will hold the returned
-semid_ds structure or semaphore value array.  Returns like ioctl: the
-undefined value for error, "0 but true" for zero, or the actual return
-value otherwise.
-.Ip "semget(KEY,NSEMS,SIZE,FLAGS)" 8 4
-Calls the System V IPC function semget.  Returns the semaphore id, or
-the undefined value if there is an error.
-.Ip "semop(KEY,OPSTRING)" 8 4
-Calls the System V IPC function semop to perform semaphore operations
-such as signaling and waiting.  OPSTRING must be a packed array of
-semop structures.  Each semop structure can be generated with
-\&'pack("sss", $semnum, $semop, $semflag)'.  The number of semaphore
-operations is implied by the length of OPSTRING.  Returns true if
-successful, or false if there is an error.  As an example, the
-following code waits on semaphore $semnum of semaphore id $semid:
-.nf
-
-	$semop = pack("sss", $semnum, -1, 0);
-	die "Semaphore trouble: $!\en" unless semop($semid, $semop);
-
-.fi
-To signal the semaphore, replace "-1" with "1".
-.Ip "send(SOCKET,MSG,FLAGS,TO)" 8 4
-.Ip "send(SOCKET,MSG,FLAGS)" 8
-Sends a message on a socket.
-Takes the same flags as the system call of the same name.
-On unconnected sockets you must specify a destination to send TO.
-Returns the number of characters sent, or the undefined value if
-there is an error.
-.Ip "setpgrp(PID,PGRP)" 8 4
-Sets the current process group for the specified PID, 0 for the current
-process.
-Will produce a fatal error if used on a machine that doesn't implement
-setpgrp(2).
-.Ip "setpriority(WHICH,WHO,PRIORITY)" 8 4
-Sets the current priority for a process, a process group, or a user.
-(See setpriority(2).)
-Will produce a fatal error if used on a machine that doesn't implement
-setpriority(2).
-.Ip "setsockopt(SOCKET,LEVEL,OPTNAME,OPTVAL)" 8 3
-Sets the socket option requested.
-Returns undefined if there is an error.
-OPTVAL may be specified as undef if you don't want to pass an argument.
-.Ip "shift(ARRAY)" 8 6
-.Ip "shift ARRAY" 8
-.Ip "shift" 8
-Shifts the first value of the array off and returns it,
-shortening the array by 1 and moving everything down.
-If there are no elements in the array, returns the undefined value.
-If ARRAY is omitted, shifts the @ARGV array in the main program, and the @_
-array in subroutines.
-(This is determined lexically.)
-See also unshift(), push() and pop().
-Shift() and unshift() do the same thing to the left end of an array that push()
-and pop() do to the right end.
-.Ip "shmctl(ID,CMD,ARG)" 8 4
-Calls the System V IPC function shmctl.  If CMD is &IPC_STAT, then ARG
-must be a variable which will hold the returned shmid_ds structure.
-Returns like ioctl: the undefined value for error, "0 but true" for
-zero, or the actual return value otherwise.
-.Ip "shmget(KEY,SIZE,FLAGS)" 8 4
-Calls the System V IPC function shmget.  Returns the shared memory
-segment id, or the undefined value if there is an error.
-.Ip "shmread(ID,VAR,POS,SIZE)" 8 4
-.Ip "shmwrite(ID,STRING,POS,SIZE)" 8
-Reads or writes the System V shared memory segment ID starting at
-position POS for size SIZE by attaching to it, copying in/out, and
-detaching from it.  When reading, VAR must be a variable which
-will hold the data read.  When writing, if STRING is too long,
-only SIZE bytes are used; if STRING is too short, nulls are
-written to fill out SIZE bytes.  Return true if successful, or
-false if there is an error.
-.Ip "shutdown(SOCKET,HOW)" 8 3
-Shuts down a socket connection in the manner indicated by HOW, which has
-the same interpretation as in the system call of the same name.
-.Ip "sin(EXPR)" 8 4
-.Ip "sin EXPR" 8
-Returns the sine of EXPR (expressed in radians).
-If EXPR is omitted, returns sine of $_.
-.Ip "sleep(EXPR)" 8 6
-.Ip "sleep EXPR" 8
-.Ip "sleep" 8
-Causes the script to sleep for EXPR seconds, or forever if no EXPR.
-May be interrupted by sending the process a SIGALRM.
-Returns the number of seconds actually slept.
-You probably cannot mix alarm() and sleep() calls, since sleep() is
-often implemented using alarm().
-.Ip "socket(SOCKET,DOMAIN,TYPE,PROTOCOL)" 8 3
-Opens a socket of the specified kind and attaches it to filehandle SOCKET.
-DOMAIN, TYPE and PROTOCOL are specified the same as for the system call
-of the same name.
-You may need to run h2ph on sys/socket.h to get the proper values handy
-in a perl library file.
-Return true if successful.
-See the example in the section on Interprocess Communication.
-.Ip "socketpair(SOCKET1,SOCKET2,DOMAIN,TYPE,PROTOCOL)" 8 3
-Creates an unnamed pair of sockets in the specified domain, of the specified
-type.
-DOMAIN, TYPE and PROTOCOL are specified the same as for the system call
-of the same name.
-If unimplemented, yields a fatal error.
-Return true if successful.
-.Ip "sort(SUBROUTINE LIST)" 8 9
-.Ip "sort(LIST)" 8
-.Ip "sort SUBROUTINE LIST" 8
-.Ip "sort BLOCK LIST" 8
-.Ip "sort LIST" 8
-Sorts the LIST and returns the sorted array value.
-Nonexistent values of arrays are stripped out.
-If SUBROUTINE or BLOCK is omitted, sorts in standard string comparison order.
-If SUBROUTINE is specified, gives the name of a subroutine that returns
-an integer less than, equal to, or greater than 0,
-depending on how the elements of the array are to be ordered.
-(The <=> and cmp operators are extremely useful in such routines.)
-SUBROUTINE may be a scalar variable name, in which case the value provides
-the name of the subroutine to use.
-In place of a SUBROUTINE name, you can provide a BLOCK as an anonymous,
-in-line sort subroutine.
-.Sp
-In the interests of efficiency the normal calling code for subroutines
-is bypassed, with the following effects: the subroutine may not be a recursive
-subroutine, and the two elements to be compared are passed into the subroutine
-not via @_ but as $a and $b (see example below).
-They are passed by reference so don't modify $a and $b.
-.Sp
-Examples:
-.nf
-
-.ne 2
-	# sort lexically
-	@articles = sort @files;
-
-.ne 2
-	# same thing, but with explicit sort routine
-	@articles = sort {$a cmp $b} @files;
-
-.ne 2
-	# same thing in reversed order
-	@articles = sort {$b cmp $a} @files;
-
-.ne 2
-	# sort numerically ascending
-	@articles = sort {$a <=> $b} @files;
-
-.ne 2
-	# sort numerically descending
-	@articles = sort {$b <=> $a} @files;
-
-.ne 5
-	# sort using explicit subroutine name
-	sub byage {
-	    $age{$a} <=> $age{$b};	# presuming integers
-	}
-	@sortedclass = sort byage @class;
-
-.ne 9
-	sub reverse { $b cmp $a; }
-	@harry = (\'dog\',\'cat\',\'x\',\'Cain\',\'Abel\');
-	@george = (\'gone\',\'chased\',\'yz\',\'Punished\',\'Axed\');
-	print sort @harry;
-		# prints AbelCaincatdogx
-	print sort reverse @harry;
-		# prints xdogcatCainAbel
-	print sort @george, \'to\', @harry;
-		# prints AbelAxedCainPunishedcatchaseddoggonetoxyz
-
-.fi
-.Ip "splice(ARRAY,OFFSET,LENGTH,LIST)" 8 8
-.Ip "splice(ARRAY,OFFSET,LENGTH)" 8
-.Ip "splice(ARRAY,OFFSET)" 8
-Removes the elements designated by OFFSET and LENGTH from an array, and
-replaces them with the elements of LIST, if any.
-Returns the elements removed from the array.
-The array grows or shrinks as necessary.
-If LENGTH is omitted, removes everything from OFFSET onward.
-The following equivalencies hold (assuming $[ == 0):
-.nf
-
-	push(@a,$x,$y)\h'|3.5i'splice(@a,$#a+1,0,$x,$y)
-	pop(@a)\h'|3.5i'splice(@a,-1)
-	shift(@a)\h'|3.5i'splice(@a,0,1)
-	unshift(@a,$x,$y)\h'|3.5i'splice(@a,0,0,$x,$y)
-	$a[$x] = $y\h'|3.5i'splice(@a,$x,1,$y);
-
-Example, assuming array lengths are passed before arrays:
-	
-	sub aeq {	# compare two array values
-		local(@a) = splice(@_,0,shift);
-		local(@b) = splice(@_,0,shift);
-		return 0 unless @a == @b;	# same len?
-		while (@a) {
-		    return 0 if pop(@a) ne pop(@b);
-		}
-		return 1;

-.fi
-.Ip "split(/PATTERN/,EXPR,LIMIT)" 8 8
-.Ip "split(/PATTERN/,EXPR)" 8 8
-.Ip "split(/PATTERN/)" 8
-.Ip "split" 8
-Splits a string into an array of strings, and returns it.
-(If not in an array context, returns the number of fields found and splits
-into the @_ array.
-(In an array context, you can force the split into @_
-by using ?? as the pattern delimiters, but it still returns the array value.))
-If EXPR is omitted, splits the $_ string.
-If PATTERN is also omitted, splits on whitespace (/[\ \et\en]+/).
-Anything matching PATTERN is taken to be a delimiter separating the fields.
-(Note that the delimiter may be longer than one character.)
-If LIMIT is specified, splits into no more than that many fields (though it
-may split into fewer).
-If LIMIT is unspecified, trailing null fields are stripped (which
-potential users of pop() would do well to remember).
-A pattern matching the null string (not to be confused with a null pattern //,
-which is just one member of the set of patterns matching a null string)
-will split the value of EXPR into separate characters at each point it
-matches that way.
-For example:
-.nf
-
-	print join(\':\', split(/ */, \'hi there\'));
-
-.fi
-produces the output \*(L'h:i:t:h:e:r:e\*(R'.
-.Sp
-The LIMIT parameter can be used to partially split a line
-.nf
-
-	($login, $passwd, $remainder) = split(\|/\|:\|/\|, $_, 3);
-
-.fi
-(When assigning to a list, if LIMIT is omitted, perl supplies a LIMIT one
-larger than the number of variables in the list, to avoid unnecessary work.
-For the list above LIMIT would have been 4 by default.
-In time critical applications it behooves you not to split into
-more fields than you really need.)
-.Sp
-If the PATTERN contains parentheses, additional array elements are created
-from each matching substring in the delimiter.
-.Sp
-	split(/([,-])/,"1-10,20");
-.Sp
-produces the array value
-.Sp
-	(1,'-',10,',',20)
-.Sp
-The pattern /PATTERN/ may be replaced with an expression to specify patterns
-that vary at runtime.
-(To do runtime compilation only once, use /$variable/o.)
-As a special case, specifying a space (\'\ \') will split on white space
-just as split with no arguments does, but leading white space does NOT
-produce a null first field.
-Thus, split(\'\ \') can be used to emulate
-.IR awk 's
-default behavior, whereas
-split(/\ /) will give you as many null initial fields as there are
-leading spaces.
-.Sp
-Example:
-.nf
-
-.ne 5
-	open(passwd, \'/etc/passwd\');
-	while (<passwd>) {
-.ie t \{\
-		($login, $passwd, $uid, $gid, $gcos, $home, $shell) = split(\|/\|:\|/\|);
-'br\}
-.el \{\
-		($login, $passwd, $uid, $gid, $gcos, $home, $shell)
-			= split(\|/\|:\|/\|);
-'br\}
-		.\|.\|.
-	}
-
-.fi
-(Note that $shell above will still have a newline on it.  See chop().)
-See also
-.IR join .
-.Ip "sprintf(FORMAT,LIST)" 8 4
-Returns a string formatted by the usual printf conventions.
-The * character is not supported.
-.Ip "sqrt(EXPR)" 8 4
-.Ip "sqrt EXPR" 8
-Return the square root of EXPR.
-If EXPR is omitted, returns square root of $_.
-.Ip "srand(EXPR)" 8 4
-.Ip "srand EXPR" 8
-Sets the random number seed for the
-.I rand
-operator.
-If EXPR is omitted, does srand(time).
-.Ip "stat(FILEHANDLE)" 8 8
-.Ip "stat FILEHANDLE" 8
-.Ip "stat(EXPR)" 8
-.Ip "stat SCALARVARIABLE" 8
-Returns a 13-element array giving the statistics for a file, either the file
-opened via FILEHANDLE, or named by EXPR.
-Returns a null list if the stat fails.
-Typically used as follows:
-.nf
-
-.ne 3
-    ($dev,$ino,$mode,$nlink,$uid,$gid,$rdev,$size,
-       $atime,$mtime,$ctime,$blksize,$blocks)
-           = stat($filename);
-
-.fi
-If stat is passed the special filehandle consisting of an underline,
-no stat is done, but the current contents of the stat structure from
-the last stat or filetest are returned.
-Example:
-.nf
-
-.ne 3
-	if (-x $file && (($d) = stat(_)) && $d < 0) {
-		print "$file is executable NFS file\en";
-	}
-
-.fi
-(This only works on machines for which the device number is negative under NFS.)
-.Ip "study(SCALAR)" 8 6
-.Ip "study SCALAR" 8
-.Ip "study"
-Takes extra time to study SCALAR ($_ if unspecified) in anticipation of
-doing many pattern matches on the string before it is next modified.
-This may or may not save time, depending on the nature and number of patterns
-you are searching on, and on the distribution of character frequencies in
-the string to be searched\*(--you probably want to compare runtimes with and
-without it to see which runs faster.
-Those loops which scan for many short constant strings (including the constant
-parts of more complex patterns) will benefit most.
-You may have only one study active at a time\*(--if you study a different
-scalar the first is \*(L"unstudied\*(R".
-(The way study works is this: a linked list of every character in the string
-to be searched is made, so we know, for example, where all the \*(L'k\*(R' characters
-are.
-From each search string, the rarest character is selected, based on some
-static frequency tables constructed from some C programs and English text.
-Only those places that contain this \*(L"rarest\*(R" character are examined.)
-.Sp
-For example, here is a loop which inserts index producing entries before any line
-containing a certain pattern:
-.nf
-
-.ne 8
-	while (<>) {
-		study;
-		print ".IX foo\en" if /\ebfoo\eb/;
-		print ".IX bar\en" if /\ebbar\eb/;
-		print ".IX blurfl\en" if /\ebblurfl\eb/;
-		.\|.\|.
-		print;
-	}
-
-.fi
-In searching for /\ebfoo\eb/, only those locations in $_ that contain \*(L'f\*(R'
-will be looked at, because \*(L'f\*(R' is rarer than \*(L'o\*(R'.
-In general, this is a big win except in pathological cases.
-The only question is whether it saves you more time than it took to build
-the linked list in the first place.
-.Sp
-Note that if you have to look for strings that you don't know till runtime,
-you can build an entire loop as a string and eval that to avoid recompiling
-all your patterns all the time.
-Together with undefining $/ to input entire files as one record, this can
-be very fast, often faster than specialized programs like fgrep.
-The following scans a list of files (@files)
-for a list of words (@words), and prints out the names of those files that
-contain a match:
-.nf
-
-.ne 12
-	$search = \'while (<>) { study;\';
-	foreach $word (@words) {
-	    $search .= "++\e$seen{\e$ARGV} if /\e\eb$word\e\eb/;\en";
-	}
-	$search .= "}";
-	@ARGV = @files;
-	undef $/;
-	eval $search;		# this screams
-	$/ = "\en";		# put back to normal input delim
-	foreach $file (sort keys(%seen)) {
-	    print $file, "\en";
-	}
-
-.fi
-.Ip "substr(EXPR,OFFSET,LEN)" 8 2
-.Ip "substr(EXPR,OFFSET)" 8 2
-Extracts a substring out of EXPR and returns it.
-First character is at offset 0, or whatever you've set $[ to.
-If OFFSET is negative, starts that far from the end of the string.
-If LEN is omitted, returns everything to the end of the string.
-You can use the substr() function as an lvalue, in which case EXPR must
-be an lvalue.
-If you assign something shorter than LEN, the string will shrink, and
-if you assign something longer than LEN, the string will grow to accommodate it.
-To keep the string the same length you may need to pad or chop your value using
-sprintf().
-.Ip "symlink(OLDFILE,NEWFILE)" 8 2
-Creates a new filename symbolically linked to the old filename.
-Returns 1 for success, 0 otherwise.
-On systems that don't support symbolic links, produces a fatal error at
-run time.
-To check for that, use eval:
-.nf
-
-	$symlink_exists = (eval \'symlink("","");\', $@ eq \'\');
-
-.fi
-.Ip "syscall(LIST)" 8 6
-.Ip "syscall LIST" 8
-Calls the system call specified as the first element of the list, passing
-the remaining elements as arguments to the system call.
-If unimplemented, produces a fatal error.
-The arguments are interpreted as follows: if a given argument is numeric,
-the argument is passed as an int.
-If not, the pointer to the string value is passed.
-You are responsible to make sure a string is pre-extended long enough
-to receive any result that might be written into a string.
-If your integer arguments are not literals and have never been interpreted
-in a numeric context, you may need to add 0 to them to force them to look
-like numbers.

-.Ip "sysread(FILEHANDLE,SCALAR,LENGTH,OFFSET)" 8 5
-.Ip "sysread(FILEHANDLE,SCALAR,LENGTH)" 8 5
-Attempts to read LENGTH bytes of data into variable SCALAR from the specified
-FILEHANDLE, using the system call read(2).
-It bypasses stdio, so mixing this with other kinds of reads may cause
-confusion.
-Returns the number of bytes actually read, or undef if there was an error.
-SCALAR will be grown or shrunk to the length actually read.
-An OFFSET may be specified to place the read data at some other place
-than the beginning of the string.
-.Ip "system(LIST)" 8 6
-.Ip "system LIST" 8
-Does exactly the same thing as \*(L"exec LIST\*(R" except that a fork
-is done first, and the parent process waits for the child process to complete.
-Note that argument processing varies depending on the number of arguments.
-The return value is the exit status of the program as returned by the wait()
-call.
-To get the actual exit value divide by 256.
-See also
-.IR exec .
-.Ip "syswrite(FILEHANDLE,SCALAR,LENGTH,OFFSET)" 8 5
-.Ip "syswrite(FILEHANDLE,SCALAR,LENGTH)" 8 5
-Attempts to write LENGTH bytes of data from variable SCALAR to the specified
-FILEHANDLE, using the system call write(2).
-It bypasses stdio, so mixing this with prints may cause
-confusion.
-Returns the number of bytes actually written, or undef if there was an error.
-An OFFSET may be specified to place the read data at some other place
-than the beginning of the string.
-.Ip "tell(FILEHANDLE)" 8 6
-.Ip "tell FILEHANDLE" 8 6
-.Ip "tell" 8
-Returns the current file position for FILEHANDLE.
-FILEHANDLE may be an expression whose value gives the name of the actual
-filehandle.
-If FILEHANDLE is omitted, assumes the file last read.
-.Ip "telldir(DIRHANDLE)" 8 5
-.Ip "telldir DIRHANDLE" 8
-Returns the current position of the readdir() routines on DIRHANDLE.
-Value may be given to seekdir() to access a particular location in
-a directory.
-Has the same caveats about possible directory compaction as the corresponding
-system library routine.
-.Ip "time" 8 4
-Returns the number of non-leap seconds since 00:00:00 UTC, January 1, 1970.
-Suitable for feeding to gmtime() and localtime().
-.Ip "times" 8 4
-Returns a four-element array giving the user and system times, in seconds, for this
-process and the children of this process.
-.Sp
-    ($user,$system,$cuser,$csystem) = times;
-.Sp
-.Ip "tr/SEARCHLIST/REPLACEMENTLIST/cds" 8 5
-.Ip "y/SEARCHLIST/REPLACEMENTLIST/cds" 8
-Translates all occurrences of the characters found in the search list with
-the corresponding character in the replacement list.
-It returns the number of characters replaced or deleted.
-If no string is specified via the =~ or !~ operator,
-the $_ string is translated.
-(The string specified with =~ must be a scalar variable, an array element,
-or an assignment to one of those, i.e. an lvalue.)
-For
-.I sed
-devotees,
-.I y
-is provided as a synonym for
-.IR tr .
-If the SEARCHLIST is delimited by bracketing quotes, the REPLACEMENTLIST
-has its own pair of quotes, which may or may not be bracketing quotes, e.g.
-tr[A-Z][a-z] or tr(+-*/)/ABCD/.
-.Sp
-If the c modifier is specified, the SEARCHLIST character set is complemented.
-If the d modifier is specified, any characters specified by SEARCHLIST that
-are not found in REPLACEMENTLIST are deleted.
-(Note that this is slightly more flexible than the behavior of some
-.I tr
-programs, which delete anything they find in the SEARCHLIST, period.)
-If the s modifier is specified, sequences of characters that were translated
-to the same character are squashed down to 1 instance of the character.
-.Sp
-If the d modifier was used, the REPLACEMENTLIST is always interpreted exactly
-as specified.
-Otherwise, if the REPLACEMENTLIST is shorter than the SEARCHLIST,
-the final character is replicated till it is long enough.
-If the REPLACEMENTLIST is null, the SEARCHLIST is replicated.
-This latter is useful for counting characters in a class, or for squashing
-character sequences in a class.
-.Sp
-Examples:
-.nf
-
-    $ARGV[1] \|=~ \|y/A\-Z/a\-z/;	\h'|3i'# canonicalize to lower case
-
-    $cnt = tr/*/*/;		\h'|3i'# count the stars in $_
-
-    $cnt = tr/0\-9//;		\h'|3i'# count the digits in $_
-
-    tr/a\-zA\-Z//s;	\h'|3i'# bookkeeper \-> bokeper
-
-    ($HOST = $host) =~ tr/a\-z/A\-Z/;
-
-    y/a\-zA\-Z/ /cs;	\h'|3i'# change non-alphas to single space
-
-    tr/\e200\-\e377/\e0\-\e177/;\h'|3i'# delete 8th bit
-
-.fi
-.Ip "truncate(FILEHANDLE,LENGTH)" 8 4
-.Ip "truncate(EXPR,LENGTH)" 8
-Truncates the file opened on FILEHANDLE, or named by EXPR, to the specified
-length.
-Produces a fatal error if truncate isn't implemented on your system.
-.Ip "umask(EXPR)" 8 4
-.Ip "umask EXPR" 8
-.Ip "umask" 8
-Sets the umask for the process and returns the old one.
-If EXPR is omitted, merely returns current umask.
-.Ip "undef(EXPR)" 8 6
-.Ip "undef EXPR" 8
-.Ip "undef" 8
-Undefines the value of EXPR, which must be an lvalue.
-Use only on a scalar value, an entire array, or a subroutine name (using &).
-(Undef will probably not do what you expect on most predefined variables or
-dbm array values.)
-Always returns the undefined value.
-You can omit the EXPR, in which case nothing is undefined, but you still
-get an undefined value that you could, for instance, return from a subroutine.
-Examples:
-.nf
-
-.ne 6
-	undef $foo;
-	undef $bar{'blurfl'};
-	undef @ary;
-	undef %assoc;
-	undef &mysub;
-	return (wantarray ? () : undef) if $they_blew_it;
-
-.fi
-.Ip "unlink(LIST)" 8 4
-.Ip "unlink LIST" 8
-Deletes a list of files.
-Returns the number of files successfully deleted.
-.nf
-
-.ne 2
-	$cnt = unlink \'a\', \'b\', \'c\';
-	unlink @goners;
-	unlink <*.bak>;
-
-.fi
-Note: unlink will not delete directories unless you are superuser and the
-.B \-U
-flag is supplied to
-.IR perl .
-Even if these conditions are met, be warned that unlinking a directory
-can inflict damage on your filesystem.
-Use rmdir instead.
-.Ip "unpack(TEMPLATE,EXPR)" 8 4
-Unpack does the reverse of pack: it takes a string representing
-a structure and expands it out into an array value, returning the array
-value.
-(In a scalar context, it merely returns the first value produced.)
-The TEMPLATE has the same format as in the pack function.
-Here's a subroutine that does substring:
-.nf
-
-.ne 4
-	sub substr {
-		local($what,$where,$howmuch) = @_;
-		unpack("x$where a$howmuch", $what);
-	}
-
-.ne 3
-and then there's
-
-	sub ord { unpack("c",$_[0]); }
-
-.fi
-In addition, you may prefix a field with a %<number> to indicate that
-you want a <number>-bit checksum of the items instead of the items themselves.
-Default is a 16-bit checksum.
-For example, the following computes the same number as the System V sum program:
-.nf
-
-.ne 4
-	while (<>) {
-	    $checksum += unpack("%16C*", $_);
-	}
-	$checksum %= 65536;
-
-.fi
-.Ip "unshift(ARRAY,LIST)" 8 4
-Does the opposite of a
-.IR shift .
-Or the opposite of a
-.IR push ,
-depending on how you look at it.
-Prepends list to the front of the array, and returns the number of elements
-in the new array.
-.nf
-
-	unshift(ARGV, \'\-e\') unless $ARGV[0] =~ /^\-/;
-
-.fi
-.Ip "utime(LIST)" 8 2
-.Ip "utime LIST" 8 2
-Changes the access and modification times on each file of a list of files.
-The first two elements of the list must be the NUMERICAL access and
-modification times, in that order.
-Returns the number of files successfully changed.
-The inode modification time of each file is set to the current time.
-Example of a \*(L"touch\*(R" command:
-.nf
-
-.ne 3
-	#!/usr/bin/perl
-	$now = time;
-	utime $now, $now, @ARGV;
-
-.fi
-.Ip "values(ASSOC_ARRAY)" 8 6
-.Ip "values ASSOC_ARRAY" 8
-Returns a normal array consisting of all the values of the named associative
-array.
-The values are returned in an apparently random order, but it is the same order
-as either the keys() or each() function would produce on the same array.
-See also keys() and each().
-.Ip "vec(EXPR,OFFSET,BITS)" 8 2
-Treats a string as a vector of unsigned integers, and returns the value
-of the bitfield specified.
-May also be assigned to.
-BITS must be a power of two from 1 to 32.
-.Sp
-Vectors created with vec() can also be manipulated with the logical operators
-|, & and ^,
-which will assume a bit vector operation is desired when both operands are
-strings.
-This interpretation is not enabled unless there is at least one vec() in
-your program, to protect older programs.
-.Sp
-To transform a bit vector into a string or array of 0's and 1's, use these:
-.nf
-
-	$bits = unpack("b*", $vector);
-	@bits = split(//, unpack("b*", $vector));
-
-.fi
-If you know the exact length in bits, it can be used in place of the *.
-.Ip "wait" 8 6
-Waits for a child process to terminate and returns the pid of the deceased
-process, or -1 if there are no child processes.
-The status is returned in $?.
-.Ip "waitpid(PID,FLAGS)" 8 6
-Waits for a particular child process to terminate and returns the pid of the deceased
-process, or -1 if there is no such child process.
-The status is returned in $?.
-If you say
-.nf
-
-	require "sys/wait.h";
-	.\|.\|.
-	waitpid(-1,&WNOHANG);
-
-.fi
-then you can do a non-blocking wait for any process.  Non-blocking wait
-is only available on machines supporting either the
-.I waitpid (2)
-or
-.I wait4 (2)
-system calls.
-However, waiting for a particular pid with FLAGS of 0 is implemented
-everywhere.  (Perl emulates the system call by remembering the status
-values of processes that have exited but have not been harvested by the
-Perl script yet.)
-.Ip "wantarray" 8 4
-Returns true if the context of the currently executing subroutine
-is looking for an array value.
-Returns false if the context is looking for a scalar.
-.nf
-
-	return wantarray ? () : undef;
-
-.fi
-.Ip "warn(LIST)" 8 4
-.Ip "warn LIST" 8
-Produces a message on STDERR just like \*(L"die\*(R", but doesn't exit.
-.Ip "write(FILEHANDLE)" 8 6
-.Ip "write(EXPR)" 8
-.Ip "write" 8
-Writes a formatted record (possibly multi-line) to the specified file,
-using the format associated with that file.
-By default the format for a file is the one having the same name is the
-filehandle, but the format for the current output channel (see
-.IR select )
-may be set explicitly
-by assigning the name of the format to the $~ variable.
-.Sp
-Top of form processing is handled automatically:
-if there is insufficient room on the current page for the formatted 
-record, the page is advanced by writing a form feed,
-a special top-of-page format is used
-to format the new page header, and then the record is written.
-By default the top-of-page format is the name of the filehandle with
-\*(L"_TOP\*(R" appended, but it may be dynamically set to the
-format of your choice by assigning the name to the $^ variable while
-the filehandle is selected.
-The number of lines remaining on the current page is in variable $-, which
-can be set to 0 to force a new page.
-.Sp
-If FILEHANDLE is unspecified, output goes to the current default output channel,
-which starts out as
-.I STDOUT
-but may be changed by the
-.I select
-operator.
-If the FILEHANDLE is an EXPR, then the expression is evaluated and the
-resulting string is used to look up the name of the FILEHANDLE at run time.
-For more on formats, see the section on formats later on.
-.Sp
-Note that write is NOT the opposite of read.
-.Sh "Precedence"
-.I Perl
-operators have the following associativity and precedence:
-.nf
-
-nonassoc\h'|1i'print printf exec system sort reverse
-\h'1.5i'chmod chown kill unlink utime die return
-left\h'|1i',
-right\h'|1i'= += \-= *= etc.
-right\h'|1i'?:
-nonassoc\h'|1i'.\|.
-left\h'|1i'||
-left\h'|1i'&&
-left\h'|1i'| ^
-left\h'|1i'&
-nonassoc\h'|1i'== != <=> eq ne cmp
-nonassoc\h'|1i'< > <= >= lt gt le ge
-nonassoc\h'|1i'chdir exit eval reset sleep rand umask
-nonassoc\h'|1i'\-r \-w \-x etc.
-left\h'|1i'<< >>
-left\h'|1i'+ \- .
-left\h'|1i'* / % x
-left\h'|1i'=~ !~ 
-right\h'|1i'! ~ and unary minus
-right\h'|1i'**
-nonassoc\h'|1i'++ \-\|\-
-left\h'|1i'\*(L'(\*(R'
-
-.fi
-As mentioned earlier, if any list operator (print, etc.) or
-any unary operator (chdir, etc.)
-is followed by a left parenthesis as the next token on the same line,
-the operator and arguments within parentheses are taken to
-be of highest precedence, just like a normal function call.
-Examples:
-.nf
-
-	chdir $foo || die;\h'|3i'# (chdir $foo) || die
-	chdir($foo) || die;\h'|3i'# (chdir $foo) || die
-	chdir ($foo) || die;\h'|3i'# (chdir $foo) || die
-	chdir +($foo) || die;\h'|3i'# (chdir $foo) || die
-
-but, because * is higher precedence than ||:
-
-	chdir $foo * 20;\h'|3i'# chdir ($foo * 20)
-	chdir($foo) * 20;\h'|3i'# (chdir $foo) * 20
-	chdir ($foo) * 20;\h'|3i'# (chdir $foo) * 20
-	chdir +($foo) * 20;\h'|3i'# chdir ($foo * 20)
-
-	rand 10 * 20;\h'|3i'# rand (10 * 20)
-	rand(10) * 20;\h'|3i'# (rand 10) * 20
-	rand (10) * 20;\h'|3i'# (rand 10) * 20
-	rand +(10) * 20;\h'|3i'# rand (10 * 20)
-
-.fi
-In the absence of parentheses,
-the precedence of list operators such as print, sort or chmod is
-either very high or very low depending on whether you look at the left
-side of operator or the right side of it.
-For example, in
-.nf
-
-	@ary = (1, 3, sort 4, 2);
-	print @ary;		# prints 1324
-
-.fi
-the commas on the right of the sort are evaluated before the sort, but
-the commas on the left are evaluated after.
-In other words, list operators tend to gobble up all the arguments that
-follow them, and then act like a simple term with regard to the preceding
-expression.
-Note that you have to be careful with parens:
-.nf
-
-.ne 3
-	# These evaluate exit before doing the print:
-	print($foo, exit);	# Obviously not what you want.
-	print $foo, exit;	# Nor is this.
-
-.ne 4
-	# These do the print before evaluating exit:
-	(print $foo), exit;	# This is what you want.
-	print($foo), exit;	# Or this.
-	print ($foo), exit;	# Or even this.
-
-Also note that
-
-	print ($foo & 255) + 1, "\en";
-
-.fi
-probably doesn't do what you expect at first glance.
-.Sh "Subroutines"
-A subroutine may be declared as follows:
-.nf
-
-    sub NAME BLOCK
-
-.fi
-.PP
-Any arguments passed to the routine come in as array @_,
-that is ($_[0], $_[1], .\|.\|.).
-The array @_ is a local array, but its values are references to the
-actual scalar parameters.
-The return value of the subroutine is the value of the last expression
-evaluated, and can be either an array value or a scalar value.
-Alternately, a return statement may be used to specify the returned value and
-exit the subroutine.
-To create local variables see the
-.I local
-operator.
-.PP
-A subroutine is called using the
-.I do
-operator or the & operator.
-.nf
-
-.ne 12
-Example:
-
-	sub MAX {
-		local($max) = pop(@_);
-		foreach $foo (@_) {
-			$max = $foo \|if \|$max < $foo;
-		}
-		$max;
-	}
-
-	.\|.\|.
-	$bestday = &MAX($mon,$tue,$wed,$thu,$fri);
-
-.ne 21
-Example:
-
-	# get a line, combining continuation lines
-	#  that start with whitespace
-	sub get_line {
-		$thisline = $lookahead;
-		line: while ($lookahead = <STDIN>) {
-			if ($lookahead \|=~ \|/\|^[ \^\e\|t]\|/\|) {
-				$thisline \|.= \|$lookahead;
-			}
-			else {
-				last line;
-			}
-		}
-		$thisline;
-	}
-
-	$lookahead = <STDIN>;	# get first line
-	while ($_ = do get_line(\|)) {
-		.\|.\|.
-	}
-
-.fi
-.nf
-.ne 6
-Use array assignment to a local list to name your formal arguments:
-
-	sub maybeset {
-		local($key, $value) = @_;
-		$foo{$key} = $value unless $foo{$key};
-	}
-
-.fi
-This also has the effect of turning call-by-reference into call-by-value,
-since the assignment copies the values.
-.Sp
-Subroutines may be called recursively.
-If a subroutine is called using the & form, the argument list is optional.
-If omitted, no @_ array is set up for the subroutine; the @_ array at the
-time of the call is visible to subroutine instead.
-.nf
-
-	do foo(1,2,3);		# pass three arguments
-	&foo(1,2,3);		# the same
-
-	do foo();		# pass a null list
-	&foo();			# the same
-	&foo;			# pass no arguments\*(--more efficient
-
-.fi
-.Sh "Passing By Reference"
-Sometimes you don't want to pass the value of an array to a subroutine but
-rather the name of it, so that the subroutine can modify the global copy
-of it rather than working with a local copy.
-In perl you can refer to all the objects of a particular name by prefixing
-the name with a star: *foo.
-When evaluated, it produces a scalar value that represents all the objects
-of that name, including any filehandle, format or subroutine.
-When assigned to within a local() operation, it causes the name mentioned
-to refer to whatever * value was assigned to it.
-Example:
-.nf
-
-	sub doubleary {
-	    local(*someary) = @_;
-	    foreach $elem (@someary) {
-		$elem *= 2;
-	    }
-	}
-	do doubleary(*foo);
-	do doubleary(*bar);
-
-.fi
-Assignment to *name is currently recommended only inside a local().
-You can actually assign to *name anywhere, but the previous referent of
-*name may be stranded forever.
-This may or may not bother you.
-.Sp
-Note that scalars are already passed by reference, so you can modify scalar
-arguments without using this mechanism by referring explicitly to the $_[nnn]
-in question.
-You can modify all the elements of an array by passing all the elements
-as scalars, but you have to use the * mechanism to push, pop or change the
-size of an array.
-The * mechanism will probably be more efficient in any case.
-.Sp
-Since a *name value contains unprintable binary data, if it is used as
-an argument in a print, or as a %s argument in a printf or sprintf, it
-then has the value '*name', just so it prints out pretty.
-.Sp
-Even if you don't want to modify an array, this mechanism is useful for
-passing multiple arrays in a single LIST, since normally the LIST mechanism
-will merge all the array values so that you can't extract out the
-individual arrays.
-.Sh "Regular Expressions"
-The patterns used in pattern matching are regular expressions such as
-those supplied in the Version 8 regexp routines.
-(In fact, the routines are derived from Henry Spencer's freely redistributable
-reimplementation of the V8 routines.)
-In addition, \ew matches an alphanumeric character (including \*(L"_\*(R") and \eW a nonalphanumeric.
-Word boundaries may be matched by \eb, and non-boundaries by \eB.
-A whitespace character is matched by \es, non-whitespace by \eS.
-A numeric character is matched by \ed, non-numeric by \eD.
-You may use \ew, \es and \ed within character classes.
-Also, \en, \er, \ef, \et and \eNNN have their normal interpretations.
-Within character classes \eb represents backspace rather than a word boundary.
-Alternatives may be separated by |.
-The bracketing construct \|(\ .\|.\|.\ \|) may also be used, in which case \e<digit>
-matches the digit'th substring.
-(Outside of the pattern, always use $ instead of \e in front of the digit.
-The scope of $<digit> (and $\`, $& and $\')
-extends to the end of the enclosing BLOCK or eval string, or to
-the next pattern match with subexpressions.
-The \e<digit> notation sometimes works outside the current pattern, but should
-not be relied upon.)
-You may have as many parentheses as you wish.  If you have more than 9
-substrings, the variables $10, $11, ... refer to the corresponding
-substring.  Within the pattern, \e10, \e11,
-etc. refer back to substrings if there have been at least that many left parens
-before the backreference.  Otherwise (for backward compatibility) \e10
-is the same as \e010, a backspace,
-and \e11 the same as \e011, a tab.
-And so on.
-(\e1 through \e9 are always backreferences.)
-.PP
-$+ returns whatever the last bracket match matched.
-$& returns the entire matched string.
-($0 used to return the same thing, but not any more.)
-$\` returns everything before the matched string.
-$\' returns everything after the matched string.
-Examples:
-.nf
-    
-	s/\|^\|([^ \|]*\|) \|*([^ \|]*\|)\|/\|$2 $1\|/;	# swap first two words
-
-.ne 5
-	if (/\|Time: \|(.\|.\|):\|(.\|.\|):\|(.\|.\|)\|/\|) {
-		$hours = $1;
-		$minutes = $2;
-		$seconds = $3;
-	}
-
-.fi
-By default, the ^ character is only guaranteed to match at the beginning
-of the string,
-the $ character only at the end (or before the newline at the end)
-and
-.I perl
-does certain optimizations with the assumption that the string contains
-only one line.
-The behavior of ^ and $ on embedded newlines will be inconsistent.
-You may, however, wish to treat a string as a multi-line buffer, such that
-the ^ will match after any newline within the string, and $ will match
-before any newline.
-At the cost of a little more overhead, you can do this by setting the variable
-$* to 1.
-Setting it back to 0 makes
-.I perl
-revert to its old behavior.
-.PP
-To facilitate multi-line substitutions, the . character never matches a newline
-(even when $* is 0).
-In particular, the following leaves a newline on the $_ string:
-.nf
-
-	$_ = <STDIN>;
-	s/.*(some_string).*/$1/;
-
-If the newline is unwanted, try one of
-
-	s/.*(some_string).*\en/$1/;
-	s/.*(some_string)[^\e000]*/$1/;
-	s/.*(some_string)(.|\en)*/$1/;
-	chop; s/.*(some_string).*/$1/;
-	/(some_string)/ && ($_ = $1);
-
-.fi
-Any item of a regular expression may be followed with digits in curly brackets
-of the form {n,m}, where n gives the minimum number of times to match the item
-and m gives the maximum.
-The form {n} is equivalent to {n,n} and matches exactly n times.
-The form {n,} matches n or more times.
-(If a curly bracket occurs in any other context, it is treated as a regular
-character.)
-The * modifier is equivalent to {0,}, the + modifier to {1,} and the ? modifier
-to {0,1}.
-There is no limit to the size of n or m, but large numbers will chew up
-more memory.
-.Sp
-You will note that all backslashed metacharacters in
-.I perl
-are alphanumeric,
-such as \eb, \ew, \en.
-Unlike some other regular expression languages, there are no backslashed
-symbols that aren't alphanumeric.
-So anything that looks like \e\e, \e(, \e), \e<, \e>, \e{, or \e} is always
-interpreted as a literal character, not a metacharacter.
-This makes it simple to quote a string that you want to use for a pattern
-but that you are afraid might contain metacharacters.
-Simply quote all the non-alphanumeric characters:
-.nf
-
-	$pattern =~ s/(\eW)/\e\e$1/g;
-
-.fi
-.Sh "Formats"
-Output record formats for use with the
-.I write
-operator may declared as follows:
-.nf
-
-.ne 3
-    format NAME =
-    FORMLIST
-    .
-
-.fi
-If name is omitted, format \*(L"STDOUT\*(R" is defined.
-FORMLIST consists of a sequence of lines, each of which may be of one of three
-types:
-.Ip 1. 4
-A comment.
-.Ip 2. 4
-A \*(L"picture\*(R" line giving the format for one output line.
-.Ip 3. 4
-An argument line supplying values to plug into a picture line.
-.PP
-Picture lines are printed exactly as they look, except for certain fields
-that substitute values into the line.
-Each picture field starts with either @ or ^.
-The @ field (not to be confused with the array marker @) is the normal
-case; ^ fields are used
-to do rudimentary multi-line text block filling.
-The length of the field is supplied by padding out the field
-with multiple <, >, or | characters to specify, respectively, left justification,
-right justification, or centering.
-As an alternate form of right justification,
-you may also use # characters (with an optional .) to specify a numeric field.
-(Use of ^ instead of @ causes the field to be blanked if undefined.)
-If any of the values supplied for these fields contains a newline, only
-the text up to the newline is printed.
-The special field @* can be used for printing multi-line values.
-It should appear by itself on a line.
-.PP
-The values are specified on the following line, in the same order as
-the picture fields.
-The values should be separated by commas.
-.PP
-Picture fields that begin with ^ rather than @ are treated specially.
-The value supplied must be a scalar variable name which contains a text
-string.
-.I Perl
-puts as much text as it can into the field, and then chops off the front
-of the string so that the next time the variable is referenced,
-more of the text can be printed.
-Normally you would use a sequence of fields in a vertical stack to print
-out a block of text.
-If you like, you can end the final field with .\|.\|., which will appear in the
-output if the text was too long to appear in its entirety.
-You can change which characters are legal to break on by changing the
-variable $: to a list of the desired characters.
-.PP
-Since use of ^ fields can produce variable length records if the text to be
-formatted is short, you can suppress blank lines by putting the tilde (~)
-character anywhere in the line.
-(Normally you should put it in the front if possible, for visibility.)
-The tilde will be translated to a space upon output.
-If you put a second tilde contiguous to the first, the line will be repeated
-until all the fields on the line are exhausted.
-(If you use a field of the @ variety, the expression you supply had better
-not give the same value every time forever!)

-It is possible to intermix prints with writes on the same output channel,
-but you'll have to handle $\- (lines left on the page) yourself.
-.PP
-If you are printing lots of fields that are usually blank, you should consider
-using the reset operator between records.
-Not only is it more efficient, but it can prevent the bug of adding another
-field and forgetting to zero it.
-.Sh "Interprocess Communication"
-The IPC facilities of perl are built on the Berkeley socket mechanism.
-If you don't have sockets, you can ignore this section.
-The calls have the same names as the corresponding system calls,
-but the arguments tend to differ, for two reasons.
-First, perl file handles work differently than C file descriptors.
-Second, perl already knows the length of its strings, so you don't need
-to pass that information.
-Here is a sample client (untested):
-.nf
-
-	($them,$port) = @ARGV;
-	$port = 2345 unless $port;
-	$them = 'localhost' unless $them;
-
-	$SIG{'INT'} = 'dokill';
-	sub dokill { kill 9,$child if $child; }
-
-	require 'sys/socket.ph';
-
-	$sockaddr = 'S n a4 x8';
-	chop($hostname = `hostname`);
-
-	($name, $aliases, $proto) = getprotobyname('tcp');
-	($name, $aliases, $port) = getservbyname($port, 'tcp')
-		unless $port =~ /^\ed+$/;
-.ie t \{\
-	($name, $aliases, $type, $len, $thisaddr) = gethostbyname($hostname);
-'br\}
-.el \{\
-	($name, $aliases, $type, $len, $thisaddr) =
-					gethostbyname($hostname);
-'br\}
-	($name, $aliases, $type, $len, $thataddr) = gethostbyname($them);
-
-	$this = pack($sockaddr, &AF_INET, 0, $thisaddr);
-	$that = pack($sockaddr, &AF_INET, $port, $thataddr);
-
-	socket(S, &PF_INET, &SOCK_STREAM, $proto) || die "socket: $!";
-	bind(S, $this) || die "bind: $!";
-	connect(S, $that) || die "connect: $!";
-
-	select(S); $| = 1; select(stdout);
-
-	if ($child = fork) {
-		while (<>) {
-			print S;
-		}
-		sleep 3;
-		do dokill();
-	}
-	else {
-		while (<S>) {
-			print;
-		}
-	}
-
-.fi
-And here's a server:
-.nf

-
-		($af,$port,$inetaddr) = unpack($sockaddr,$addr);

-.Sh "Predefined Names"
-The following names have special meaning to
-.IR perl .
-I could have used alphabetic symbols for some of these, but I didn't want
-to take the chance that someone would say reset \*(L"a\-zA\-Z\*(R" and wipe them all
-out.
-You'll just have to suffer along with these silly symbols.
-Most of them have reasonable mnemonics, or analogues in one of the shells.
-.Ip $_ 8
-The default input and pattern-searching space.
-The following pairs are equivalent:
-.nf
-
-.ne 2
-	while (<>) {\|.\|.\|.	# only equivalent in while!
-	while ($_ = <>) {\|.\|.\|.
-
-.ne 2
-	/\|^Subject:/
-	$_ \|=~ \|/\|^Subject:/
-
-.ne 2
-	y/a\-z/A\-Z/
-	$_ =~ y/a\-z/A\-Z/
-
-.ne 2
-	chop
-	chop($_)
-
-.fi 
-(Mnemonic: underline is understood in certain operations.)
-.Ip $. 8
-The current input line number of the last filehandle that was read.
-Readonly.
-Remember that only an explicit close on the filehandle resets the line number.
-Since <> never does an explicit close, line numbers increase across ARGV files
-(but see examples under eof).
-(Mnemonic: many programs use . to mean the current line number.)
-.Ip $/ 8
-The input record separator, newline by default.
-Works like
-.IR awk 's
-RS variable, including treating blank lines as delimiters
-if set to the null string.
-You may set it to a multicharacter string to match a multi-character
-delimiter.
-Note that setting it to "\en\en" means something slightly different
-than setting it to "", if the file contains consecutive blank lines.
-Setting it to "" will treat two or more consecutive blank lines as a single
-blank line.
-Setting it to "\en\en" will blindly assume that the next input character
-belongs to the next paragraph, even if it's a newline.
-(Mnemonic: / is used to delimit line boundaries when quoting poetry.)
-.Ip $, 8
-The output field separator for the print operator.
-Ordinarily the print operator simply prints out the comma separated fields
-you specify.
-In order to get behavior more like
-.IR awk ,
-set this variable as you would set
-.IR awk 's
-OFS variable to specify what is printed between fields.
-(Mnemonic: what is printed when there is a , in your print statement.)
-.Ip $"" 8
-This is like $, except that it applies to array values interpolated into
-a double-quoted string (or similar interpreted string).
-Default is a space.
-(Mnemonic: obvious, I think.)
-.Ip $\e 8
-The output record separator for the print operator.
-Ordinarily the print operator simply prints out the comma separated fields
-you specify, with no trailing newline or record separator assumed.
-In order to get behavior more like
-.IR awk ,
-set this variable as you would set
-.IR awk 's
-ORS variable to specify what is printed at the end of the print.
-(Mnemonic: you set $\e instead of adding \en at the end of the print.
-Also, it's just like /, but it's what you get \*(L"back\*(R" from
-.IR perl .)
-.Ip $# 8
-The output format for printed numbers.
-This variable is a half-hearted attempt to emulate
-.IR awk 's
-OFMT variable.
-There are times, however, when
-.I awk
-and
-.I perl
-have differing notions of what
-is in fact numeric.
-Also, the initial value is %.20g rather than %.6g, so you need to set $#
-explicitly to get
-.IR awk 's
-value.
-(Mnemonic: # is the number sign.)
-.Ip $% 8
-The current page number of the currently selected output channel.
-(Mnemonic: % is page number in nroff.)
-.Ip $= 8
-The current page length (printable lines) of the currently selected output
-channel.
-Default is 60.
-(Mnemonic: = has horizontal lines.)
-.Ip $\- 8
-The number of lines left on the page of the currently selected output channel.
-(Mnemonic: lines_on_page \- lines_printed.)
-.Ip $~ 8
-The name of the current report format for the currently selected output
-channel.
-Default is name of the filehandle.
-(Mnemonic: brother to $^.)
-.Ip $^ 8
-The name of the current top-of-page format for the currently selected output
-channel.
-Default is name of the filehandle with \*(L"_TOP\*(R" appended.
-(Mnemonic: points to top of page.)
-.Ip $| 8
-If set to nonzero, forces a flush after every write or print on the currently
-selected output channel.
-Default is 0.
-Note that
-.I STDOUT
-will typically be line buffered if output is to the
-terminal and block buffered otherwise.
-Setting this variable is useful primarily when you are outputting to a pipe,
-such as when you are running a
-.I perl
-script under rsh and want to see the
-output as it's happening.
-(Mnemonic: when you want your pipes to be piping hot.)
-.Ip $$ 8
-The process number of the
-.I perl
-running this script.
-(Mnemonic: same as shells.)
-.Ip $? 8
-The status returned by the last pipe close, backtick (\`\`) command or
-.I system
-operator.
-Note that this is the status word returned by the wait() system
-call, so the exit value of the subprocess is actually ($? >> 8).
-$? & 255 gives which signal, if any, the process died from, and whether
-there was a core dump.
-(Mnemonic: similar to sh and ksh.)
-.Ip $& 8 4
-The string matched by the last successful pattern match
-(not counting any matches hidden
-within a BLOCK or eval enclosed by the current BLOCK).
-(Mnemonic: like & in some editors.)
-.Ip $\` 8 4
-The string preceding whatever was matched by the last successful pattern match
-(not counting any matches hidden within a BLOCK or eval enclosed by the current
-BLOCK).
-(Mnemonic: \` often precedes a quoted string.)
-.Ip $\' 8 4
-The string following whatever was matched by the last successful pattern match
-(not counting any matches hidden within a BLOCK or eval enclosed by the current
-BLOCK).
-(Mnemonic: \' often follows a quoted string.)
-Example:
-.nf
-
-.ne 3
-	$_ = \'abcdefghi\';
-	/def/;
-	print "$\`:$&:$\'\en";  	# prints abc:def:ghi
-
-.fi
-.Ip $+ 8 4
-The last bracket matched by the last search pattern.
-This is useful if you don't know which of a set of alternative patterns
-matched.
-For example:
-.nf
-
-    /Version: \|(.*\|)|Revision: \|(.*\|)\|/ \|&& \|($rev = $+);
-
-.fi
-(Mnemonic: be positive and forward looking.)
-.Ip $* 8 2
-Set to 1 to do multiline matching within a string, 0 to tell
-.I perl
-that it can assume that strings contain a single line, for the purpose
-of optimizing pattern matches.
-Pattern matches on strings containing multiple newlines can produce confusing
-results when $* is 0.
-Default is 0.
-(Mnemonic: * matches multiple things.)
-Note that this variable only influences the interpretation of ^ and $.
-A literal newline can be searched for even when $* == 0.
-.Ip $0 8
-Contains the name of the file containing the
-.I perl
-script being executed.
-Assigning to $0 modifies the argument area that the ps(1) program sees.
-(Mnemonic: same as sh and ksh.)
-.Ip $<digit> 8
-Contains the subpattern from the corresponding set of parentheses in the last
-pattern matched, not counting patterns matched in nested blocks that have
-been exited already.
-(Mnemonic: like \edigit.)
-.Ip $[ 8 2
-The index of the first element in an array, and of the first character in
-a substring.
-Default is 0, but you could set it to 1 to make
-.I perl
-behave more like
-.I awk
-(or Fortran)
-when subscripting and when evaluating the index() and substr() functions.
-(Mnemonic: [ begins subscripts.)
-.Ip $] 8 2
-The string printed out when you say \*(L"perl -v\*(R".
-It can be used to determine at the beginning of a script whether the perl
-interpreter executing the script is in the right range of versions.
-If used in a numeric context, returns the version + patchlevel / 1000.
-Example:
-.nf
-
-.ne 8
-	# see if getc is available
-        ($version,$patchlevel) =
-		 $] =~ /(\ed+\e.\ed+).*\enPatch level: (\ed+)/;
-        print STDERR "(No filename completion available.)\en"
-		 if $version * 1000 + $patchlevel < 2016;
-
-or, used numerically,
-
-	warn "No checksumming!\en" if $] < 3.019;
-
-.fi
-(Mnemonic: Is this version of perl in the right bracket?)
-.Ip $; 8 2
-The subscript separator for multi-dimensional array emulation.
-If you refer to an associative array element as
-.nf
-	$foo{$a,$b,$c}
-
-it really means
-
-	$foo{join($;, $a, $b, $c)}
-
-But don't put
-
-	@foo{$a,$b,$c}		# a slice\*(--note the @
-
-which means
-
-	($foo{$a},$foo{$b},$foo{$c})
-
-.fi
-Default is "\e034", the same as SUBSEP in
-.IR awk .
-Note that if your keys contain binary data there might not be any safe
-value for $;.
-(Mnemonic: comma (the syntactic subscript separator) is a semi-semicolon.
-Yeah, I know, it's pretty lame, but $, is already taken for something more
-important.)
-.Ip $! 8 2
-If used in a numeric context, yields the current value of errno, with all the
-usual caveats.
-(This means that you shouldn't depend on the value of $! to be anything
-in particular unless you've gotten a specific error return indicating a
-system error.)
-If used in a string context, yields the corresponding system error string.
-You can assign to $! in order to set errno
-if, for instance, you want $! to return the string for error n, or you want
-to set the exit value for the die operator.
-(Mnemonic: What just went bang?)
-.Ip $@ 8 2
-The perl syntax error message from the last eval command.
-If null, the last eval parsed and executed correctly (although the operations
-you invoked may have failed in the normal fashion).
-(Mnemonic: Where was the syntax error \*(L"at\*(R"?)
-.Ip $< 8 2
-The real uid of this process.
-(Mnemonic: it's the uid you came FROM, if you're running setuid.)
-.Ip $> 8 2
-The effective uid of this process.
-Example:
-.nf
-
-.ne 2
-	$< = $>;	# set real uid to the effective uid
-	($<,$>) = ($>,$<);	# swap real and effective uid
-
-.fi
-(Mnemonic: it's the uid you went TO, if you're running setuid.)
-Note: $< and $> can only be swapped on machines supporting setreuid().
-.Ip $( 8 2
-The real gid of this process.
-If you are on a machine that supports membership in multiple groups
-simultaneously, gives a space separated list of groups you are in.
-The first number is the one returned by getgid(), and the subsequent ones
-by getgroups(), one of which may be the same as the first number.
-(Mnemonic: parentheses are used to GROUP things.
-The real gid is the group you LEFT, if you're running setgid.)
-.Ip $) 8 2
-The effective gid of this process.
-If you are on a machine that supports membership in multiple groups
-simultaneously, gives a space separated list of groups you are in.
-The first number is the one returned by getegid(), and the subsequent ones
-by getgroups(), one of which may be the same as the first number.
-(Mnemonic: parentheses are used to GROUP things.
-The effective gid is the group that's RIGHT for you, if you're running setgid.)
-.Sp
-Note: $<, $>, $( and $) can only be set on machines that support the
-corresponding set[re][ug]id() routine.
-$( and $) can only be swapped on machines supporting setregid().
-.Ip $: 8 2
-The current set of characters after which a string may be broken to
-fill continuation fields (starting with ^) in a format.
-Default is "\ \en-", to break on whitespace or hyphens.
-(Mnemonic: a \*(L"colon\*(R" in poetry is a part of a line.)
-.Ip $^D 8 2
-The current value of the debugging flags.
-(Mnemonic: value of
-.B \-D
-switch.)
-.Ip $^F 8 2
-The maximum system file descriptor, ordinarily 2.  System file descriptors
-are passed to subprocesses, while higher file descriptors are not.
-During an open, system file descriptors are preserved even if the open
-fails.  Ordinary file descriptors are closed before the open is attempted.
-.Ip $^I 8 2
-The current value of the inplace-edit extension.
-Use undef to disable inplace editing.
-(Mnemonic: value of
-.B \-i
-switch.)
-.Ip $^L 8 2
-What formats output to perform a formfeed.  Default is \ef.
-.Ip $^P 8 2
-The internal flag that the debugger clears so that it doesn't
-debug itself.  You could conceivable disable debugging yourself
-by clearing it.
-.Ip $^T 8 2
-The time at which the script began running, in seconds since the epoch.
-The values returned by the
-.B \-M ,
-.B \-A
-and
-.B \-C
-filetests are based on this value.
-.Ip $^W 8 2
-The current value of the warning switch.
-(Mnemonic: related to the
-.B \-w
-switch.)
-.Ip $^X 8 2
-The name that Perl itself was executed as, from argv[0].
-.Ip $ARGV 8 3
-contains the name of the current file when reading from <>.
-.Ip @ARGV 8 3
-The array ARGV contains the command line arguments intended for the script.
-Note that $#ARGV is the generally number of arguments minus one, since
-$ARGV[0] is the first argument, NOT the command name.
-See $0 for the command name.
-.Ip @INC 8 3
-The array INC contains the list of places to look for
-.I perl
-scripts to be
-evaluated by the \*(L"do EXPR\*(R" command or the \*(L"require\*(R" command.
-It initially consists of the arguments to any
-.B \-I
-command line switches, followed
-by the default
-.I perl
-library, probably \*(L"/usr/share/perl\*(R",
-followed by \*(L".\*(R", to represent the current directory.
-.Ip %INC 8 3
-The associative array INC contains entries for each filename that has
-been included via \*(L"do\*(R" or \*(L"require\*(R".
-The key is the filename you specified, and the value is the location of
-the file actually found.
-The \*(L"require\*(R" command uses this array to determine whether
-a given file has already been included.
-.Ip $ENV{expr} 8 2
-The associative array ENV contains your current environment.
-Setting a value in ENV changes the environment for child processes.
-.Ip $SIG{expr} 8 2
-The associative array SIG is used to set signal handlers for various signals.
-Example:
-.nf
-
-.ne 12
-	sub handler {	# 1st argument is signal name
-		local($sig) = @_;
-		print "Caught a SIG$sig\-\|\-shutting down\en";
-		close(LOG);
-		exit(0);
-	}
-
-	$SIG{\'INT\'} = \'handler\';
-	$SIG{\'QUIT\'} = \'handler\';
-	.\|.\|.
-	$SIG{\'INT\'} = \'DEFAULT\';	# restore default action
-	$SIG{\'QUIT\'} = \'IGNORE\';	# ignore SIGQUIT
-
-.fi
-The SIG array only contains values for the signals actually set within
-the perl script.
-.Sh "Packages"
-Perl provides a mechanism for alternate namespaces to protect packages from
-stomping on each others variables.
-By default, a perl script starts compiling into the package known as \*(L"main\*(R".
-By use of the
-.I package
-declaration, you can switch namespaces.
-The scope of the package declaration is from the declaration itself to the end
-of the enclosing block (the same scope as the local() operator).
-Typically it would be the first declaration in a file to be included by
-the \*(L"require\*(R" operator.
-You can switch into a package in more than one place; it merely influences
-which symbol table is used by the compiler for the rest of that block.
-You can refer to variables and filehandles in other packages by prefixing
-the identifier with the package name and a single quote.
-If the package name is null, the \*(L"main\*(R" package as assumed.
-.PP
-Only identifiers starting with letters are stored in the packages symbol
-table.
-All other symbols are kept in package \*(L"main\*(R".
-In addition, the identifiers STDIN, STDOUT, STDERR, ARGV, ARGVOUT, ENV, INC
-and SIG are forced to be in package \*(L"main\*(R", even when used for
-other purposes than their built-in one.
-Note also that, if you have a package called \*(L"m\*(R", \*(L"s\*(R"
-or \*(L"y\*(R", the you can't use the qualified form of an identifier since it
-will be interpreted instead as a pattern match, a substitution
-or a translation.
-.PP
-Eval'ed strings are compiled in the package in which the eval was compiled
-in.
-(Assignments to $SIG{}, however, assume the signal handler specified is in the
-main package.
-Qualify the signal handler name if you wish to have a signal handler in
-a package.)
-For an example, examine perldb.pl in the perl library.
-It initially switches to the DB package so that the debugger doesn't interfere
-with variables in the script you are trying to debug.
-At various points, however, it temporarily switches back to the main package
-to evaluate various expressions in the context of the main package.
-.PP
-The symbol table for a package happens to be stored in the associative array
-of that name prepended with an underscore.
-The value in each entry of the associative array is
-what you are referring to when you use the *name notation.
-In fact, the following have the same effect (in package main, anyway),
-though the first is more
-efficient because it does the symbol table lookups at compile time:
-.nf
-
-.ne 2
-	local(*foo) = *bar;
-	local($_main{'foo'}) = $_main{'bar'};
-
-.fi
-You can use this to print out all the variables in a package, for instance.
-Here is dumpvar.pl from the perl library:
-.nf
-.ne 11
-	package dumpvar;
-
-	sub main'dumpvar {
-	\&    ($package) = @_;
-	\&    local(*stab) = eval("*_$package");
-	\&    while (($key,$val) = each(%stab)) {
-	\&        {
-	\&            local(*entry) = $val;
-	\&            if (defined $entry) {
-	\&                print "\e$$key = '$entry'\en";
-	\&            }

-Note that, even though the subroutine is compiled in package dumpvar, the
-name of the subroutine is qualified so that its name is inserted into package
-\*(L"main\*(R".
-.Sh "Style"
-Each programmer will, of course, have his or her own preferences in regards
-to formatting, but there are some general guidelines that will make your
-programs easier to read.
-.Ip 1. 4 4
-Just because you CAN do something a particular way doesn't mean that
-you SHOULD do it that way.
-.I Perl
-is designed to give you several ways to do anything, so consider picking
-the most readable one.
-For instance
-
-	open(FOO,$foo) || die "Can't open $foo: $!";
-
-is better than
-
-	die "Can't open $foo: $!" unless open(FOO,$foo);
-
-because the second way hides the main point of the statement in a
-modifier.
-On the other hand
-
-	print "Starting analysis\en" if $verbose;
-
-is better than
-
-	$verbose && print "Starting analysis\en";
-
-since the main point isn't whether the user typed -v or not.
-.Sp
-Similarly, just because an operator lets you assume default arguments
-doesn't mean that you have to make use of the defaults.
-The defaults are there for lazy systems programmers writing one-shot
-programs.
-If you want your program to be readable, consider supplying the argument.
-.Sp
-Along the same lines, just because you
-.I can
-omit parentheses in many places doesn't mean that you ought to:
-.nf
-
-	return print reverse sort num values array;
-	return print(reverse(sort num (values(%array))));
-
-.fi
-When in doubt, parenthesize.
-At the very least it will let some poor schmuck bounce on the % key in vi.
-.Sp
-Even if you aren't in doubt, consider the mental welfare of the person who
-has to maintain the code after you, and who will probably put parens in
-the wrong place.
-.Ip 2. 4 4
-Don't go through silly contortions to exit a loop at the top or the
-bottom, when
-.I perl
-provides the "last" operator so you can exit in the middle.
-Just outdent it a little to make it more visible:
-.nf
-
-.ne 7
-    line:
-	for (;;) {
-	    statements;
-	last line if $foo;
-	    next line if /^#/;
-	    statements;
-	}
-
-.fi
-.Ip 3. 4 4
-Don't be afraid to use loop labels\*(--they're there to enhance readability as
-well as to allow multi-level loop breaks.
-See last example.
-.Ip 4. 4 4
-For portability, when using features that may not be implemented on every
-machine, test the construct in an eval to see if it fails.
-If you know what version or patchlevel a particular feature was implemented,
-you can test $] to see if it will be there.
-.Ip 5. 4 4
-Choose mnemonic identifiers.
-.Ip 6. 4 4
-Be consistent.
-.Sh "Debugging"
-If you invoke
-.I perl
-with a
-.B \-d
-switch, your script will be run under a debugging monitor.
-It will halt before the first executable statement and ask you for a
-command, such as:
-.Ip "h" 12 4
-Prints out a help message.
-.Ip "T" 12 4
-Stack trace.
-.Ip "s" 12 4
-Single step.
-Executes until it reaches the beginning of another statement.
-.Ip "n" 12 4
-Next.
-Executes over subroutine calls, until it reaches the beginning of the 
-next statement.
-.Ip "f" 12 4
-Finish.
-Executes statements until it has finished the current subroutine.
-.Ip "c" 12 4
-Continue.
-Executes until the next breakpoint is reached.
-.Ip "c line" 12 4
-Continue to the specified line.
-Inserts a one-time-only breakpoint at the specified line.
-.Ip "<CR>" 12 4
-Repeat last n or s.
-.Ip "l min+incr" 12 4
-List incr+1 lines starting at min.
-If min is omitted, starts where last listing left off.
-If incr is omitted, previous value of incr is used.
-.Ip "l min-max" 12 4
-List lines in the indicated range.
-.Ip "l line" 12 4
-List just the indicated line.
-.Ip "l" 12 4
-List next window.
-.Ip "-" 12 4
-List previous window.
-.Ip "w line" 12 4
-List window around line.
-.Ip "l subname" 12 4
-List subroutine.
-If it's a long subroutine it just lists the beginning.
-Use \*(L"l\*(R" to list more.
-.Ip "/pattern/" 12 4
-Regular expression search forward for pattern; the final / is optional.
-.Ip "?pattern?" 12 4
-Regular expression search backward for pattern; the final ? is optional.
-.Ip "L" 12 4
-List lines that have breakpoints or actions.
-.Ip "S" 12 4
-Lists the names of all subroutines.
-.Ip "t" 12 4
-Toggle trace mode on or off.
-.Ip "b line condition" 12 4
-Set a breakpoint.
-If line is omitted, sets a breakpoint on the 
-line that is about to be executed.
-If a condition is specified, it is evaluated each time the statement is
-reached and a breakpoint is taken only if the condition is true.
-Breakpoints may only be set on lines that begin an executable statement.
-.Ip "b subname condition" 12 4
-Set breakpoint at first executable line of subroutine.
-.Ip "d line" 12 4
-Delete breakpoint.
-If line is omitted, deletes the breakpoint on the 
-line that is about to be executed.
-.Ip "D" 12 4
-Delete all breakpoints.
-.Ip "a line command" 12 4
-Set an action for line.
-A multi-line command may be entered by backslashing the newlines.
-.Ip "A" 12 4
-Delete all line actions.
-.Ip "< command" 12 4
-Set an action to happen before every debugger prompt.
-A multi-line command may be entered by backslashing the newlines.
-.Ip "> command" 12 4
-Set an action to happen after the prompt when you've just given a command
-to return to executing the script.
-A multi-line command may be entered by backslashing the newlines.
-.Ip "V package" 12 4
-List all variables in package.
-Default is main package.
-.Ip "! number" 12 4
-Redo a debugging command.
-If number is omitted, redoes the previous command.
-.Ip "! -number" 12 4
-Redo the command that was that many commands ago.
-.Ip "H -number" 12 4
-Display last n commands.
-Only commands longer than one character are listed.
-If number is omitted, lists them all.
-.Ip "q or ^D" 12 4
-Quit.
-.Ip "command" 12 4
-Execute command as a perl statement.
-A missing semicolon will be supplied.
-.Ip "p expr" 12 4
-Same as \*(L"print DB'OUT expr\*(R".
-The DB'OUT filehandle is opened to /dev/tty, regardless of where STDOUT
-may be redirected to.
-.PP
-If you want to modify the debugger, copy perldb.pl from the perl library
-to your current directory and modify it as necessary.
-(You'll also have to put -I. on your command line.)
-You can do some customization by setting up a .perldb file which contains
-initialization code.
-For instance, you could make aliases like these:
-.nf
-
-    $DB'alias{'len'} = 's/^len(.*)/p length($1)/';
-    $DB'alias{'stop'} = 's/^stop (at|in)/b/';
-    $DB'alias{'.'} =
-      's/^\e./p "\e$DB\e'sub(\e$DB\e'line):\et",\e$DB\e'line[\e$DB\e'line]/';

-.fi
-.Sh "Setuid Scripts"
-.I Perl
-is designed to make it easy to write secure setuid and setgid scripts.
-Unlike shells, which are based on multiple substitution passes on each line
-of the script,
-.I perl
-uses a more conventional evaluation scheme with fewer hidden \*(L"gotchas\*(R".
-Additionally, since the language has more built-in functionality, it
-has to rely less upon external (and possibly untrustworthy) programs to
-accomplish its purposes.
-.PP
-In an unpatched 4.2 or 4.3bsd kernel, setuid scripts are intrinsically
-insecure, but this kernel feature can be disabled.
-If it is,
-.I perl
-can emulate the setuid and setgid mechanism when it notices the otherwise
-useless setuid/gid bits on perl scripts.
-If the kernel feature isn't disabled,
-.I perl
-will complain loudly that your setuid script is insecure.
-You'll need to either disable the kernel setuid script feature, or put
-a C wrapper around the script.
-.PP
-When perl is executing a setuid script, it takes special precautions to
-prevent you from falling into any obvious traps.
-(In some ways, a perl script is more secure than the corresponding
-C program.)
-Any command line argument, environment variable, or input is marked as
-\*(L"tainted\*(R", and may not be used, directly or indirectly, in any
-command that invokes a subshell, or in any command that modifies files,
-directories or processes.
-Any variable that is set within an expression that has previously referenced
-a tainted value also becomes tainted (even if it is logically impossible
-for the tainted value to influence the variable).
-For example:
-.nf
-
-.ne 5
-	$foo = shift;			# $foo is tainted
-	$bar = $foo,\'bar\';		# $bar is also tainted
-	$xxx = <>;			# Tainted
-	$path = $ENV{\'PATH\'};	# Tainted, but see below
-	$abc = \'abc\';			# Not tainted
-
-.ne 4
-	system "echo $foo";		# Insecure
-	system "/bin/echo", $foo;	# Secure (doesn't use sh)
-	system "echo $bar";		# Insecure
-	system "echo $abc";		# Insecure until PATH set
-
-.ne 5
-	$ENV{\'PATH\'} = \'/bin:/usr/bin\';
-	$ENV{\'IFS\'} = \'\' if $ENV{\'IFS\'} ne \'\';
-
-	$path = $ENV{\'PATH\'};	# Not tainted
-	system "echo $abc";		# Is secure now!
-
-.ne 5
-	open(FOO,"$foo");		# OK
-	open(FOO,">$foo"); 		# Not OK
-
-	open(FOO,"echo $foo|");	# Not OK, but...
-	open(FOO,"-|") || exec \'echo\', $foo;	# OK
-
-	$zzz = `echo $foo`;		# Insecure, zzz tainted
-
-	unlink $abc,$foo;		# Insecure
-	umask $foo;			# Insecure
-
-.ne 3
-	exec "echo $foo";		# Insecure
-	exec "echo", $foo;		# Secure (doesn't use sh)
-	exec "sh", \'-c\', $foo;	# Considered secure, alas
-
-.fi
-The taintedness is associated with each scalar value, so some elements
-of an array can be tainted, and others not.
-.PP
-If you try to do something insecure, you will get a fatal error saying 
-something like \*(L"Insecure dependency\*(R" or \*(L"Insecure PATH\*(R".
-Note that you can still write an insecure system call or exec,
-but only by explicitly doing something like the last example above.
-You can also bypass the tainting mechanism by referencing
-subpatterns\*(--\c
-.I perl
-presumes that if you reference a substring using $1, $2, etc, you knew
-what you were doing when you wrote the pattern:
-.nf
-
-	$ARGV[0] =~ /^\-P(\ew+)$/;
-	$printer = $1;		# Not tainted
-
-.fi
-This is fairly secure since \ew+ doesn't match shell metacharacters.
-Use of .+ would have been insecure, but
-.I perl
-doesn't check for that, so you must be careful with your patterns.
-This is the ONLY mechanism for untainting user supplied filenames if you
-want to do file operations on them (unless you make $> equal to $<).
-.PP
-It's also possible to get into trouble with other operations that don't care
-whether they use tainted values.
-Make judicious use of the file tests in dealing with any user-supplied
-filenames.
-When possible, do opens and such after setting $> = $<.
-.I Perl
-doesn't prevent you from opening tainted filenames for reading, so be
-careful what you print out.
-The tainting mechanism is intended to prevent stupid mistakes, not to remove
-the need for thought.
-.SH ENVIRONMENT
-.Ip HOME 12 4
-Used if chdir has no argument.
-.Ip LOGDIR 12 4
-Used if chdir has no argument and HOME is not set.
-.Ip PATH 12 4
-Used in executing subprocesses, and in finding the script if \-S
-is used.
-.Ip PERLLIB 12 4
-A colon-separated list of directories in which to look for Perl library
-files before looking in the standard library and the current directory.
-.Ip PERLDB 12 4
-The command used to get the debugger code.  If unset, uses
-.br
-
-	require 'perldb.pl'
-
-.PP
-Apart from these,
-.I perl
-uses no other environment variables, except to make them available
-to the script being executed, and to child processes.
-However, scripts running setuid would do well to execute the following lines
-before doing anything else, just to keep people honest:
-.nf
-
-.ne 3
-    $ENV{\'PATH\'} = \'/bin:/usr/bin\';    # or whatever you need
-    $ENV{\'SHELL\'} = \'/bin/sh\' if $ENV{\'SHELL\'} ne \'\';
-    $ENV{\'IFS\'} = \'\' if $ENV{\'IFS\'} ne \'\';

-.SH TRAPS
-Accustomed

-users should take special note of the following:
-.Ip * 4 2
-Semicolons are required after all simple statements in
-.I perl
-(except at the end of a block).
-Newline is not a statement delimiter.
-.Ip * 4 2
-Curly brackets are required on ifs and whiles.
-.Ip * 4 2
-Variables begin with $ or @ in

-.Ip * 4 2
-Arrays index from 0 unless you set $[.
-Likewise string positions in substr() and index().
-.Ip * 4 2
-You have to decide whether your array has numeric or string indices.
-.Ip * 4 2
-Associative array values do not spring into existence upon mere reference.
-.Ip * 4 2
-You have to decide whether you want to use string or numeric comparisons.
-.Ip * 4 2
-Reading an input line does not split it for you.  You get to split it yourself
-to an array.
-And the
-.I split
-operator has different arguments.
-.Ip * 4 2
-The current input line is normally in $_, not $0.
-It generally does not have the newline stripped.
-($0 is the name of the program executed.)
-.Ip * 4 2
-$<digit> does not refer to fields\*(--it refers to substrings matched by the last
-match pattern.
-.Ip * 4 2
-The
-.I print
-statement does not add field and record separators unless you set
-$, and $\e.
-.Ip * 4 2
-You must open your files before you print to them.
-.Ip * 4 2
-The range operator is \*(L".\|.\*(R", not comma.
-(The comma operator works as in C.)
-.Ip * 4 2
-The match operator is \*(L"=~\*(R", not \*(L"~\*(R".
-(\*(L"~\*(R" is the one's complement operator, as in C.)
-.Ip * 4 2
-The exponentiation operator is \*(L"**\*(R", not \*(L"^\*(R".
-(\*(L"^\*(R" is the XOR operator, as in C.)
-.Ip * 4 2
-The concatenation operator is \*(L".\*(R", not the null string.
-(Using the null string would render \*(L"/pat/ /pat/\*(R" unparsable,
-since the third slash would be interpreted as a division operator\*(--the
-tokener is in fact slightly context sensitive for operators like /, ?, and <.
-And in fact, . itself can be the beginning of a number.)

-
-.fi
-.PP
-The descriptions of alarm and sleep refer to signal SIGALARM.  These

-.PP
-The
-.B \-0
-switch to set the initial value of $/ was added to Perl after the book
-went to press.
-.PP
-The
-.B \-l
-switch now does automatic line ending processing.
-.PP
-The qx// construct is now a synonym for backticks.
-.PP
-$0 may now be assigned to set the argument displayed by
-.I ps (1).
-.PP
-The new @###.## format was omitted accidentally from the description
-on formats.
-.PP
-It wasn't known at press time that s///ee caused multiple evaluations of
-the replacement expression.  This is to be construed as a feature.
-.PP
-(LIST) x $count now does array replication.
-.PP
-There is now no limit on the number of parentheses in a regular expression.
-.PP
-In double-quote context, more escapes are supported: \ee, \ea, \ex1b, \ec[,
-\el, \eL, \eu, \eU, \eE.  The latter five control up/lower case translation.
-.PP
-The
-.B $/
-variable may now be set to a multi-character delimiter.
-.PP
-There is now a g modifier on ordinary pattern matching that causes it
-to iterate through a string finding multiple matches.
-.PP
-All of the $^X variables are new except for $^T.

-The default top-of-form format for FILEHANDLE is now FILEHANDLE_TOP rather
-than top.

- * The "internal use only" fields in regexp.h are present to pass info from
- * compile to execute that permits the execute phase to run lots faster on
- * simple cases.  They are:
- *
- * regstart	str that must begin a match; Nullch if none obvious
- * reganch	is the match anchored (at beginning-of-line only)?
- * regmust	string (pointer into program) that match must include, or NULL
- *  [regmust changed to STR* for bminstr()--law]
- * regmlen	length of regmust string
- *  [regmlen not used currently]
- *
- * Regstart and reganch permit very fast decisions on suitable starting points
- * for a match, cutting down the work a lot.  Regmust permits fast rejection
- * of lines that cannot possibly match.  The regmust tests are costly enough
- * that regcomp() supplies a regmust only if the r.e. contains something
- * potentially expensive (at present, the only such thing detected is * or +
- * at the start of the r.e., which can involve a lot of backup).  Regmlen is
- * supplied because the test in regexec() needs it and regcomp() is computing
- * it anyway.
- * [regmust is now supplied always.  The tests that use regmust have a
- * heuristic that disables the test if it usually matches.]
- *
- * [In fact, we now use regmust in many cases to locate where the search
- * starts in the string, so if regback is >= 0, the regmust search is never
- * wasted effort.  The regback variable says how many characters back from
- * where regmust matched is the earliest possible start of the match.
- * For instance, /[a-z].foo/ has a regmust of 'foo' and a regback of 2.]

- * Structure for regexp "program".  This is essentially a linear encoding
- * of a nondeterministic finite-state machine (aka syntax charts or
- * "railroad normal form" in parsing technology).  Each node is an opcode
- * plus a "next" pointer, possibly plus an operand.  "Next" pointers of
- * all nodes except BRANCH implement concatenation; a "next" pointer with
- * a BRANCH on both ends of it is connecting two alternatives.  (Here we
- * have one of the subtle syntax dependencies:  an individual BRANCH (as
- * opposed to a collection of them) is never concatenated with anything
- * because of operator precedence.)  The operand of some types of node is
- * a literal string; for others, it is a node leading into a sub-FSM.  In
- * particular, the operand of a BRANCH node is the first node of the branch.
- * (NB this is *not* a tree structure:  the tail of the branch connects
- * to the thing following the set of BRANCHes.)  The opcodes are:

- * Opcode notes:
- *
- * BRANCH	The set of branches constituting a single choice are hooked
- *		together with their "next" pointers, since precedence prevents
- *		anything being concatenated to any individual branch.  The
- *		"next" pointer of the last BRANCH in a choice points to the
- *		thing following the whole choice.  This is also where the
- *		final "next" pointer of each individual branch points; each
- *		branch starts with the operand node of a BRANCH node.
- *
- * BACK		Normal "next" pointers all implicitly point forward; BACK
- *		exists to make loop structures possible.
- *
- * STAR,PLUS	'?', and complex '*' and '+', are implemented as circular
- *		BRANCH structures using BACK.  Simple cases (one character
- *		per match) are implemented with STAR and PLUS for speed
- *		and to minimize recursive plunges.
- *
- * OPEN,CLOSE	...are numbered at compile time.

-This is the perl test library.  To run all the tests, just type 'TEST'.
-
-To add new tests, just look at the current tests and do likewise.
-
-If a test fails, run it by itself to see if it prints any informative
-diagnostics.  If not, modify the test to print informative diagnostics.
-If you put out extra lines with a '#' character on the front, you don't
-have to worry about removing the extra print statements later since TEST
-ignores lines beginning with '#'.
-
-If you come up with new tests, send them to lwall@netlabs.com.

-[ Note:  This directory was actually brought in to be able to use curseperl,
-  but it's also a useful reference for general extension ]
-
-This directory contains an example of how you might link in C subroutines
-with perl to make your own special copy of perl.  In the perl distribution
-directory, there will be (after make is run) a file called uperl.o, which
-is all of perl except for a single undefined subroutine, named userinit().
-See usersub.c.
-
-The sole purpose of the userinit() routine is to call the initialization
-routines for any modules that you want to link in.  In this example, we just
-call init_curses(), which sets up to link in the System V curses routines.
-You'll find this in the file curses.c, which is the processed output of
-curses.mus.  (To get BSD curses, replace curses.mus with bsdcurses.mus.)
-
-The magicname() routine adds variable names into the symbol table.  Along
-with the name of the variable as Perl knows it, we pass a structure containing
-an index identifying the variable, and the names of two C functions that
-know how to set or evaluate a variable given the index of the variable.
-Our example uses a macro to handle this conveniently.
-
-The init routine calls make_usub() to add user-defined subroutine names
-into the symbol table.  The arguments are
-
-	make_usub(subname, subindex, subfunc, filename);
-	char *subname;
-	int subindex;
-	int subfunc();
-	char *filename;

-The subname is the name that will be used in the Perl program.  The subindex
-will be passed to subfunc() when it is called to tell it which C function
-is desired.  subfunc() is a glue routine that translates the arguments
-from Perl internal stack form to the form required by the routine in
-question, calls the desired C function, and then translates any return
-value back into the stack format.  The glue routine used by curses just
-has a large switch statement, each branch of which does the processing
-for a particular C function.  The subindex could, however, be used to look
-up a function in a dynamically linked library.  No example of this is
-provided.
-
-As a help in producing the glue routine, a preprocessor called "mus" lets
-you specify argument and return value types in a tabular format.  An entry
-such as:
-
-    CASE int waddstr
-    I       WINDOW*         win
-    I       char*           str
-    END
-
-indicates that waddstr takes two input arguments, the first of which is a
-pointer to a window, and the second of which is an ordinary C string.  It
-also indicates that an integer is returned.  The mus program turns this into:
-
-    case US_waddstr:
-        if (items != 2)
-            fatal("Usage: &waddstr($win, $str)");
-        else {
-            int retval;
-            WINDOW*     win =           *(WINDOW**)     str_get(st[1]);
-            char*       str =           (char*)         str_get(st[2]);
-
-            retval = waddstr(win, str);
-            str_numset(st[0], (double) retval);
-        }
-        return sp;
-
-It's also possible to have output parameters, indicated by O, and input/ouput
-parameters indicated by IO.
-
-The mus program isn't perfect.  You'll note that curses.mus has some
-cases which are hand coded.  They'll be passed straight through unmodified.
-You can produce similar cases by analogy to what's in curses.c, as well
-as similar routines in the doarg.c, dolist.c and doio.c routines of Perl.
-The mus program is only intended to get you about 90% there.  It's not clear,
-for instance, how a given structure should be passed to Perl.  But that
-shouldn't bother you--if you've gotten this far, it's already obvious
-that you are totally mad.
-
-Here's an example of how to return an array value:
-
-    case US_appl_errlist:
-	if (!wantarray) {
-	    str_numset(st[0], (double) appl_nerr);
-	    return sp;
-	}
-	astore(stack, sp + appl_nerr, Nullstr);		/* extend stack */
-	st = stack->ary_array + sp;			/* possibly realloced */
-	for (i = 0; i < appl_nerr; i++) {
-	    tmps = appl_errlist[i];
-	    st[i] = str_2mortal(str_make(tmps,strlen(tmps)));
-	}
-	return sp + appl_nerr - 1;
-
-
-In addition, there is a program, man2mus, that will scan a man page for
-function prototypes and attempt to construct a mus CASE entry for you.  It has
-to guess about input/output parameters, so you'll have to tidy up after it.
-But it can save you a lot of time if the man pages for a library are
-reasonably well formed.
-
-If you happen to have curses on your machine, you might try compiling
-a copy of curseperl.  The "pager" program in this directory is a rudimentary
-start on writing a pager--don't believe the help message, which is stolen
-from the less program.
-
-User-defined subroutines may not currently be called as a signal handler,
-though a signal handler may itself call a user-defined subroutine.
-
-There are now glue routines to call back from C into Perl.  In usersub.c
-in this directory, you'll find callback() and callv().  The callback()
-routine presumes that any arguments to pass to the Perl subroutine
-have already been pushed onto the Perl stack.  The callv() routine
-is a wrapper that pushes an argv-style array of strings onto the
-stack for you, and then calls callback().  Be sure to recheck your
-stack pointer after returning from these routine, since the Perl code
-may have reallocated it.

-.SH NAME
-a2p - Awk to Perl translator
-.SH SYNOPSIS
-.B a2p [options] filename
-.SH DESCRIPTION
-.I A2p
-takes an awk script specified on the command line (or from standard input)
-and produces a comparable
-.I perl
-script on the standard output.
-.Sh "Options"
-Options include:
-.TP 5
-.B \-D<number>
-sets debugging flags.
-.TP 5
-.B \-F<character>
-tells a2p that this awk script is always invoked with this -F switch.
-.TP 5
-.B \-n<fieldlist>
-specifies the names of the input fields if input does not have to be split into
-an array.
-If you were translating an awk script that processes the password file, you
-might say:
-.sp
-	a2p -7 -nlogin.password.uid.gid.gcos.shell.home
-.sp
-Any delimiter can be used to separate the field names.
-.TP 5
-.B \-<number>
-causes a2p to assume that input will always have that many fields.
-.Sh "Considerations"
-A2p cannot do as good a job translating as a human would, but it usually
-does pretty well.
-There are some areas where you may want to examine the perl script produced
-and tweak it some.
-Here are some of them, in no particular order.
-.PP
-There is an awk idiom of putting int() around a string expression to force
-numeric interpretation, even though the argument is always integer anyway.
-This is generally unneeded in perl, but a2p can't tell if the argument
-is always going to be integer, so it leaves it in.
-You may wish to remove it.
-.PP
-Perl differentiates numeric comparison from string comparison.
-Awk has one operator for both that decides at run time which comparison
-to do.
-A2p does not try to do a complete job of awk emulation at this point.
-Instead it guesses which one you want.
-It's almost always right, but it can be spoofed.
-All such guesses are marked with the comment \*(L"#???\*(R".
-You should go through and check them.
-You might want to run at least once with the \-w switch to perl, which
-will warn you if you use == where you should have used eq.
-.PP
-Perl does not attempt to emulate the behavior of awk in which nonexistent
-array elements spring into existence simply by being referenced.
-If somehow you are relying on this mechanism to create null entries for
-a subsequent for...in, they won't be there in perl.
-.PP
-If a2p makes a split line that assigns to a list of variables that looks
-like (Fld1, Fld2, Fld3...) you may want
-to rerun a2p using the \-n option mentioned above.
-This will let you name the fields throughout the script.
-If it splits to an array instead, the script is probably referring to the number
-of fields somewhere.
-.PP
-The exit statement in awk doesn't necessarily exit; it goes to the END
-block if there is one.
-Awk scripts that do contortions within the END block to bypass the block under
-such circumstances can be simplified by removing the conditional
-in the END block and just exiting directly from the perl script.
-.PP
-Perl has two kinds of array, numerically-indexed and associative.
-Awk arrays are usually translated to associative arrays, but if you happen
-to know that the index is always going to be numeric you could change
-the {...} to [...].
-Iteration over an associative array is done using the keys() function, but
-iteration over a numeric array is NOT.
-You might need to modify any loop that is iterating over the array in question.
-.PP
-Awk starts by assuming OFMT has the value %.6g.
-Perl starts by assuming its equivalent, $#, to have the value %.20g.
-You'll want to set $# explicitly if you use the default value of OFMT.
-.PP
-Near the top of the line loop will be the split operation that is implicit in
-the awk script.
-There are times when you can move this down past some conditionals that
-test the entire record so that the split is not done as often.
-.PP
-For aesthetic reasons you may wish to change the array base $[ from 1 back
-to perl's default of 0, but remember to change all array subscripts AND
-all substr() and index() operations to match.
-.PP
-Cute comments that say "# Here is a workaround because awk is dumb" are passed
-through unmodified.
-.PP
-Awk scripts are often embedded in a shell script that pipes stuff into and
-out of awk.
-Often the shell script wrapper can be incorporated into the perl script, since
-perl can start up pipes into and out of itself, and can do other things that
-awk can't do by itself.
-.PP
-Scripts that refer to the special variables RSTART and RLENGTH can often
-be simplified by referring to the variables $`, $& and $', as long as they
-are within the scope of the pattern match that sets them.
-.PP
-The produced perl script may have subroutines defined to deal with awk's
-semantics regarding getline and print.
-Since a2p usually picks correctness over efficiency.
-it is almost always possible to rewrite such code to be more efficient by
-discarding the semantic sugar.
-.PP
-For efficiency, you may wish to remove the keyword from any return statement
-that is the last statement executed in a subroutine.
-A2p catches the most common case, but doesn't analyze embedded blocks for
-subtler cases.
-.PP
-ARGV[0] translates to $ARGV0, but ARGV[n] translates to $ARGV[$n].
-A loop that tries to iterate over ARGV[0] won't find it.
-.SH ENVIRONMENT
-A2p uses no environment variables.
-.SH AUTHOR
-Larry Wall <lwall@jpl-devvax.Jpl.Nasa.Gov>
-.SH FILES
-.SH SEE ALSO
-perl	The perl compiler/interpreter
-.br
-s2p	sed to perl translator
-.SH DIAGNOSTICS
-.SH BUGS
-It would be possible to emulate awk's behavior in selecting string versus
-numeric operations at run time by inspection of the operands, but it would
-be gross and inefficient.
-Besides, a2p almost always guesses right.
-.PP
-Storage for the awk syntax tree is currently static, and can run out.

-.SH SYNOPSIS
-.B h2ph [headerfiles]
-.SH DESCRIPTION
-.I h2ph
-converts any C header files specified to the corresponding Perl header file
-format.
-It is most easily run while in /usr/include:
-.nf
-
-	cd /usr/include; h2ph * sys/*
-
-.fi
-If run with no arguments, filters standard input to standard output.
-.SH ENVIRONMENT
-No environment variables are used.
-.SH FILES
-/usr/include/*.h
-.br
-/usr/include/sys/*.h
-.br
-etc.
-.SH AUTHOR
-Larry Wall
-.SH "SEE ALSO"
-perl(1)
-.SH DIAGNOSTICS
-The usual warnings if it can't read or write the files involved.
-.SH BUGS
-Doesn't construct the %sizeof array for you.
-.PP
-It doesn't handle all C constructs, but it does attempt to isolate
-definitions inside evals so that you can get at the definitions
-that it can translate.
-.PP
-It's only intended as a rough tool.
-You may need to dicker with the files produced.

-.SH NAME
-s2p - Sed to Perl translator
-.SH SYNOPSIS
-.B s2p [options] filename
-.SH DESCRIPTION
-.I S2p
-takes a sed script specified on the command line (or from standard input)
-and produces a comparable
-.I perl
-script on the standard output.
-.Sh "Options"
-Options include:
-.TP 5
-.B \-D<number>
-sets debugging flags.
-.TP 5
-.B \-n
-specifies that this sed script was always invoked with a sed -n.
-Otherwise a switch parser is prepended to the front of the script.
-.TP 5
-.B \-p
-specifies that this sed script was never invoked with a sed -n.
-Otherwise a switch parser is prepended to the front of the script.
-.Sh "Considerations"
-The perl script produced looks very sed-ish, and there may very well be
-better ways to express what you want to do in perl.
-For instance, s2p does not make any use of the split operator, but you might
-want to.
-.PP
-The perl script you end up with may be either faster or slower than the original
-sed script.
-If you're only interested in speed you'll just have to try it both ways.
-Of course, if you want to do something sed doesn't do, you have no choice.
-It's often possible to speed up the perl script by various methods, such
-as deleting all references to $\e and chop.
-.SH ENVIRONMENT
-S2p uses no environment variables.
