+             Didn't fix to be strict-proof because the module uses &foo; and

+             Make the UTF-8 decoding stricter and more verbose when
+             malformation happens.  This involved adding an argument

+             scan_bin(), scan_oct(), scan_hex(), and reg_uni().

+

+             
+             save_re_context() could reset PL_curcop to freed memory, causing core

+=head2 64 bit support.
+
+If your platform does not have 64 bits natively, but can simulate them with
+compiler flags and/or C<long long> or C<int64_t>, you can build a perl that
+uses 64 bits.
+
+There are actually two modes of 64-bitness: the first one is achieved
+using Configure -Duse64bitint and the second one using Configure
+-Duse64bitall.  The difference is that the first one is minimal and
+the second one maximal.  The first works in more places than the second.
+
+The C<use64bitint> does only as much as is required to get 64-bit
+integers into Perl (this may mean, for example, using "long longs")
+while your memory may still be limited to 2 gigabytes (because your
+pointers could still be 32-bit).  Note that the name C<64bitint> does
+not imply that your C compiler will be using 64-bit C<int>s (it might,
+but it doesn't have to): the C<use64bitint> means that you will be
+able to have 64 bits wide scalar values.
+
+The C<use64bitall> goes all the way by attempting to switch also
+integers (if it can), longs (and pointers) to being 64-bit.  This may
+create an even more binary incompatible Perl than -Duse64bitint: the
+resulting executable may not run at all in a 32-bit box, or you may
+have to reboot/reconfigure/rebuild your operating system to be 64-bit
+aware.
+
+Natively 64-bit systems like Alpha and Cray need neither -Duse64bitint
+nor -Duse64bitall.
+
+    NOTE: 64-bit support is still experimental on most platforms.
+    Existing support only covers the LP64 data model.  In particular, the
+    LLP64 data model is not yet supported.  64-bit libraries and system

+=item Test failures from lib/ftmp-security saying "system possibly insecure"
+
+Firstly, test failures from the ftmp-security are not necessarily
+serious or indicative of a real security threat.  That being said,
+they bear investigating.
+
+The tests may fail for the following reasons.   Note that each of the
+tests is run both in the building directory and the temporary
+directory, as returned by File::Spec->tmpdir().
+
+(1) If the directory the tests are being run is owned by somebody else
+than the user running the tests, or root (uid 0).  This failure can
+happen if the Perl source code distribution is unpacked in a way that
+the user ids in the distribution package are used as-is.  Some tar
+programs do this.
+
+(2) If the directory the test are being run in is writable by group
+or by other (remember: with UNIX/POSIX semantics, write access to
+a directory means the right to add/remove files in that directory),
+and there is no sticky bit set in the directory.  'Sticky bit' is
+a feature used in some UNIXes to give extra protection to files: if
+the bit is on a directory, no one but the owner (or the root) can remove
+that file even if the permissions of the directory would allow file
+removal by others.  This failure can happen if the permissions in the
+directory simply are a bit too liberal for the tests' liking.  This
+may or may not be a real problem: it depends on the permissions policy
+used on this particular directory/project/system/site.  This failure
+can also happen if the system either doesn't support the sticky bit
+(this is the case with many non-UNIX platforms: in principle the
+File::Temp should know about these platforms and skip the tests), or
+if the system supports the sticky bit but for some reason or reasons
+it is not being used.  This is for example the case with HP-UX: as of
+HP-UX release 11.00, the sticky bit is very much supported, but HP-UX
+doesn't use it on its /tmp directory as shipped.  Also as with the
+permissions, some local policy might dictate that the stickiness is
+not used.
+
+(3) If the system supports the POSIX 'chown giveaway' feature and if
+any of the parent directories of the temporary file back to the root
+directory are 'unsafe', using the definitions given above in (1) and

+(SvCUR) is overloaded for other purposes and can't be relied on here.

+This method returns the name of the glob, but if the first

+
+It's useful if you want to print out the name of a variable.
+If you restrict yourself to globs which exist at compile-time
+then the result ought to be unambiguous, because code like
+C<${"^G"} = 1> is compiled as two ops - a constant string and
+a dereference (rv2gv) - so that the glob is created at runtime.

+If you're working with globs at runtime, and need to disambiguate
+*^G from *{"^G"}, then you should use the raw NAME method.

+=item B<-x>I<LEVEL>
+
+Expand conventional syntax constructions into equivalent ones that expose
+their internal operation. I<LEVEL> should be a digit, with higher values
+meaning more expansion. As with B<-q>, this actually involves turning off
+special cases in B::Deparse's normal operations.
+
+If I<LEVEL> is at least 3, for loops will be translated into equivalent
+while loops with continue blocks; for instance
+
+    for ($i = 0; $i < 10; ++$i) {
+        print $i;
+    }
+
+turns into
+
+    $i = 0;
+    while ($i < 10) {
+        print $i;
+    } continue {
+        ++$i
+    }
+
+Note that in a few cases this translation can't be perfectly carried back
+into the source code -- if the loop's initializer declares a my variable,
+for instance, it won't have the correct scope outside of the loop.
+
+If I<LEVEL> is at least 7, if statements will be translated into equivalent
+expressions using C<&&>, C<?:> and C<do {}>; for instance
+
+    print 'hi' if $nice;
+    if ($nice) {
+        print 'hi';
+    }
+    if ($nice) {
+        print 'hi';
+    } else {
+        print 'bye';
+    }
+
+turns into
+
+    $nice and print 'hi';
+    $nice and do { print 'hi' };
+    $nice ? do { print 'hi' } : do { print 'bye' };
+
+Long sequences of elsifs will turn into nested ternary operators, which
+B::Deparse doesn't know how to indent nicely.

+
+   * DB_File.pm & the test hasness now use the warnings pragma (when

+=head2 Memory footprint debugging
+
+When perl is compiled with support for memory footprint debugging
+(default with Perl's malloc()), Devel::Peek provides an access to this API.
+
+Use mstat() function to emit a memory state statistic to the terminal.
+For more information on the format of output of mstat() see
+L<perldebug/Using C<$ENV{PERL_DEBUG_MSTATS}>>.
+
+Three additional functions allow access to this statistic from Perl.
+First, use C<mstats_fillhash(%hash)> to get the information contained
+in the output of mstat() into %hash. The field of this hash are
+
+  minbucket nbuckets sbrk_good sbrk_slack sbrked_remains sbrks start_slack
+  topbucket topbucket_ev topbucket_odd total total_chain total_sbrk totfree
+
+Two additional fields C<free>, C<used> contain array references which
+provide per-bucket count of free and used chunks.  Two other fields
+C<mem_size>, C<available_size> contain array references which provide
+the information about the allocated size and usable size of chunks in
+each bucket.  Again, see L<perldebug/Using C<$ENV{PERL_DEBUG_MSTATS}>>
+for details.
+
+Keep in mind that only the first several "odd-numbered" buckets are
+used, so the information on size of the "odd-numbered" buckets which are
+not used is probably meaningless.
+
+The information in
+
+ mem_size available_size minbucket nbuckets
+
+is the property of a particular build of perl, and does not depend on
+the current process.  If you do not provide the optional argument to
+the functions mstats_fillhash(), fill_mstats(), mstats2hash(), then
+the information in fields C<mem_size>, C<available_size> is not
+updated.
+
+C<fill_mstats($buf)> is a much cheaper call (both speedwise and
+memory-wise) which collects the statistic into $buf in
+machine-readable form.  At a later moment you may need to call
+C<mstats2hash($buf, %hash)> to use this information to fill %hash.
+
+All three APIs C<fill_mstats($buf)>, C<mstats_fillhash(%hash)>, and
+C<mstats2hash($buf, %hash)> are designed to allocate no memory if used
+I<the second time> on the same $buf and/or %hash.
+
+So, if you want to collect memory info in a cycle, you may call
+
+  $#buf = 999;
+  fill_mstats($_) for @buf;
+  mstats_fillhash(%report, 1);		# Static info too
+
+  foreach (@buf) {
+    # Do something...
+    fill_mstats $_;			# Collect statistic
+  }
+  foreach (@buf) {
+    mstats2hash($_, %report);		# Preserve static info
+    # Do something with %report
+  }

+Mac OS (Classic) users should note a few differences. Since
+Mac OS is not Unix, when the glob code encounters a tilde glob (e.g.
+~user/foo) and the C<GLOB_TILDE> flag is used, it simply returns that
+pattern without doing any expansion.
+
+Glob on Mac OS is case-insensitive by default (if you don't use any
+flags). If you specify any flags at all and still want glob
+to be case-insensitive, you must include C<GLOB_NOCASE> in the flags.
+
+The path separator is ':' (aka colon), not '/' (aka slash). Mac OS users
+should be careful about specifying relative pathnames. While a full path
+always begins with a volume name, a relative pathname should always
+begin with a ':'.  If specifying a volume name only, a trailing ':' is
+required.

-=head1 DESCRIPTION
+=over 4
+
+=item 1.
+
+The hash variable you want to tie.
+
+=item 2. 
+
+The string C<"NDBM_File">.  (Ths tells Perl to use the C<NDBM_File>
+package to perform the functions of the hash.)
+
+=item 3. 
+
+The name of the file you want to tie to the hash.

+Read-only access to the data in the file.

+=item C<O_WRONLY>
+
+Write-only access to the data in the file.
+
+=item C<O_RDWR>
+
+Both read and write access.
+
+=back
+
+If you want to create the file if it does not exist, add C<O_CREAT> to
+any of these, as in the example.  If you omit C<O_CREAT> and the file
+does not already exist, the C<tie> call will fail.
+
+=item 5.
+
+The default permissions to use if a new file is created.  The actual
+permissions will be modified by the user's umask, so you should
+probably use 0666 here. (See L<perlfunc/umask>.)
+
+=back
+
+=head1 DIAGNOSTICS
+
+On failure, the C<tie> call returns an undefined value and probably
+sets C<$!> to contain the reason the file could not be tied.
+
+=head2 C<ndbm store returned -1, errno 22, key "..." at ...>
+
+This warning is emmitted when you try to store a key or a value that
+is too long.  It means that the change was not recorded in the
+database.  See BUGS AND WARNINGS below.
+
+=head1 BUGS AND WARNINGS
+
+There are a number of limits on the size of the data that you can
+store in the NDBM file.  The most important is that the length of a
+key, plus the length of its associated value, may not exceed 1008
+bytes.

- untie %h;
+Use C<ODBM_File> with the Perl built-in C<tie> function to establish
+the connection between the variable and the file.  The arguments to
+C<tie> should be:
 
-=head1 DESCRIPTION
+=over 4
+
+=item 1.
+
+The hash variable you want to tie.
+
+=item 2. 
+
+The string C<"ODBM_File">.  (Ths tells Perl to use the C<ODBM_File>
+package to perform the functions of the hash.)
+
+=item 3. 
+
+The name of the file you want to tie to the hash.  
+
+=item 4.
+
+Flags.  Use one of:
+
+=over 2
+
+=item C<O_RDONLY>
+
+Read-only access to the data in the file.
+
+=item C<O_WRONLY>
+
+Write-only access to the data in the file.
+
+=item C<O_RDWR>
+
+Both read and write access.
+
+=back
+
+If you want to create the file if it does not exist, add C<O_CREAT> to
+any of these, as in the example.  If you omit C<O_CREAT> and the file
+does not already exist, the C<tie> call will fail.
+
+=item 5.
+
+The default permissions to use if a new file is created.  The actual
+permissions will be modified by the user's umask, so you should
+probably use 0666 here. (See L<perlfunc/umask>.)
+
+=back
+
+=head1 DIAGNOSTICS
+
+On failure, the C<tie> call returns an undefined value and probably
+sets C<$!> to contain the reason the file could not be tied.
+
+=head2 C<odbm store returned -1, errno 22, key "..." at ...>
+
+This warning is emmitted when you try to store a key or a value that
+is too long.  It means that the change was not recorded in the
+database.  See BUGS AND WARNINGS below.
+
+=head1 BUGS AND WARNINGS
+
+There are a number of limits on the size of the data that you can
+store in the ODBM file.  The most important is that the length of a
+key, plus the length of its associated value, may not exceed 1008
+bytes.

 =head1 DESCRIPTION
 
-See L<perlfunc/tie>, L<perldbmfilter>
+C<SDBM_File> establishes a connection between a Perl hash variable and
+a file in SDBM_File format;.  You can manipulate the data in the file
+just as if it were in a Perl hash, but when your program exits, the
+data will remain in the file, to be used the next time your program
+runs.
+
+Use C<SDBM_File> with the Perl built-in C<tie> function to establish
+the connection between the variable and the file.  The arguments to
+C<tie> should be:
+
+=over 4
+
+=item 1.
+
+The hash variable you want to tie.
+
+=item 2. 
+
+The string C<"SDBM_File">.  (Ths tells Perl to use the C<SDBM_File>
+package to perform the functions of the hash.)
+
+=item 3. 
+
+The name of the file you want to tie to the hash.  
+
+=item 4.
+
+Flags.  Use one of:
+
+=over 2
+
+=item C<O_RDONLY>
+
+Read-only access to the data in the file.
+
+=item C<O_WRONLY>
+
+Write-only access to the data in the file.
+
+=item C<O_RDWR>
+
+Both read and write access.
+
+=back
+
+If you want to create the file if it does not exist, add C<O_CREAT> to
+any of these, as in the example.  If you omit C<O_CREAT> and the file
+does not already exist, the C<tie> call will fail.
+
+=item 5.
+
+The default permissions to use if a new file is created.  The actual
+permissions will be modified by the user's umask, so you should
+probably use 0666 here. (See L<perlfunc/umask>.)
+
+=back
+
+=head1 DIAGNOSTICS
+
+On failure, the C<tie> call returns an undefined value and probably
+sets C<$!> to contain the reason the file could not be tied.
+
+=head2 C<sdbm store returned -1, errno 22, key "..." at ...>
+
+This warning is emmitted when you try to store a key or a value that
+is too long.  It means that the change was not recorded in the
+database.  See BUGS AND WARNINGS below.
+
+=head1 BUGS AND WARNINGS
+
+There are a number of limits on the size of the data that you can
+store in the SDBM file.  The most important is that the length of a
+key, plus the length of its associated value, may not exceed 1008
+bytes.
+
+See L<perlfunc/tie>, L<perldbmfilter>, L<Fcntl>

 #
+# A: Yes.  There are two MPE problems here.  The 'undef' functions exist on MPE,
+# but are merely dummy routines that return ENOTIMPL or ESYSERR.  Since they're
+# useless, let's just tell Perl to avoid them.  Also, a few data items are
+# 'undef' because while they may exist in structures, they are uninitialized.
+#
+# The 'define' cases are a bit weirder.  MPE has a libc.a, libc.sl, and two
+# special kernel shared libraries, /SYS/PUB/XL and /SYS/PUB/NL.  Much of what
+# is in libc.a is duplicated within XL and NL, so when we created libc.sl, we
+# omitted the duplicated functions.  Since Configure end ups scanning libc.sl,
+# we need to 'define' the functions that had been removed.
+#
+# We don't want to scan XL or NL because we would find way too many POSIX or

------
-Generic notes about building Perl5 on Solaris:
-- Use /usr/ccs/bin/make.
-- If you use GNU make, remove its setgid bit.
-- Remove all instances of *ucb* from your path.
-- Make sure libucb is not in /usr/lib (it should be in /usr/ucblib).
-- Do not use GNU as or GNU ld, or any of GNU binutils or GNU libc.
-- Do not use /usr/ucb/cc.
-- Do not change Configure's default answers, except for the path names.
-- Do not use -lmalloc.
-- Do not build on SunOS 4 and expect it to work properly on SunOS 5.
-- /dev/fd must be mounted if you want set-uid scripts to work.

-Here are the gcc-related questions and answers from the Solaris 2 FAQ.  Note
-the themes:
-	- run fixincludes
-	- run fixincludes correctly
-	- don't use GNU as or GNU ld
-
-Question 5.7 covers the __builtin_va_alist problem people are always seeing.
-Question 6.1.3 covers the GNU as and GNU ld issues which are always biting
-people.
-Question 6.9 is for those who are still trying to compile Perl4.
-
-The latest Solaris 2 FAQ can be found in the following locations:
-	rtfm.mit.edu:/pub/usenet-by-group/comp.sys.sun.admin
-	ftp.fwi.uva.nl:/pub/solaris
-
-Perl5 comes with a script in the top-level directory called "myconfig" which
-will print a summary of the configuration in your config.sh.  My summary for
-Solaris 2.4 and gcc 2.6.3 follows.  I have also built with gcc 2.7.0 and the
-results are identical.  This configuration was generated with Configure's -d
-option (take all defaults, don't bother prompting me).  All tests pass for
-Perl5.001, patch.1m.
-

-From: Casper.Dik@Holland.Sun.COM (Casper H.S. Dik - Network Security Engineer)
-Subject: Solaris 2 Frequently Asked Questions (FAQ) 1.48
-Date: 25 Jul 1995 12:20:18 GMT
-
-5.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined?
-
-    You're using gcc without properly installing the gcc fixed
-    include files.  Or you ran fixincludes after installing gcc
-    w/o moving the gcc supplied varargs.h and stdarg.h files
-    out of the way and moving them back again later.  This often
-    happens when people install gcc from a binary distribution.
-    If there's a tmp directory in gcc's include directory, fixincludes
-    didn't complete.  You should have run "just-fixinc" instead.
-
-    Another possible cause is using ``gcc -I/usr/include.''
-
-6.1) Where is the C compiler or where can I get one?
-
-    [...]
-
-    3) Gcc.
-
-    Gcc is available from the GNU archives in source and binary
-    form.  Look in a directory called sparc-sun-solaris2 for
-    binaries.  You need gcc 2.3.3 or later.  You should not use
-    GNU as or GNU ld.  Make sure you run just-fixinc if you use
-    a binary distribution.  Better is to get a binary version and
-    use that to bootstrap gcc from source.
-
-    [...]
-
-    When you install gcc, don't make the mistake of installing
-    GNU binutils or GNU libc, they are not as capable as their
-    counterparts you get with Solaris 2.x.
-
-6.9) I can't get perl 4.036 to compile or run.
-
-    Run Configure, and use the solaris_2_0 hints, *don't* use
-    the solaris_2_1 hints and don't use the config.sh you may
-    already have.  First you must make sure Configure and make
-    don't find /usr/ucb/cc.  (It must use gcc or the native C
-    compiler: /opt/SUNWspro/bin/cc)
-
-    Some questions need a special answer.
-
-    Are your system (especially dbm) libraries compiled with gcc? [y] y
-
-    yes: gcc 2.3.3 or later uses the standard calling
-    conventions, same as Sun's C.
-
-    Any additional cc flags? [ -traditional -Dvolatile=__volatile__
-    -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__
-    Remove /usr/ucbinclude.
-
-    Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm
-    -lucb] -lsocket -lnsl  -lm
-
-    Don't include -ldbm, -lmalloc and -lucb.
-
-    Perl 5 compiled out of the box.
-
-7.0) 64-bitness, from Alan Burlison (added by jhi 2000-02-21)
-
-  You need a machine running Solaris 2.7 or above.
-
-  Here's some rules:
-  
-  1. Solaris 2.7 and above will run in either 32 bit or 64 bit mode,
-     via a reboot.
-  2. You can build 64 bit apps whilst running 32 bit mode and vice-versa.
-  3. 32 bit apps will run under Solaris running in either 32 or 64 bit mode.
-  4. 64 bit apps require Solaris to be running 64 bit mode
-  5. It is possible to select the appropriate 32 or 64 bit version of an
-     app at run-time using isaexec(3).
-  6. You can detect the OS mode using "isainfo -v", e.g.
-      fubar$ isainfo -v   # Ultra 30 in 64 bit mode
-      64-bit sparcv9 applications
-      32-bit sparc applications
-  7. To compile 64 bit you need to use the flag "-xarch=v9".
-     getconf(1) will tell you this, e.g.
-      fubar$ getconf -a | grep v9
-      XBS5_LP64_OFF64_CFLAGS:         -xarch=v9
-      XBS5_LP64_OFF64_LDFLAGS:        -xarch=v9
-      XBS5_LP64_OFF64_LINTFLAGS:      -xarch=v9
-      XBS5_LPBIG_OFFBIG_CFLAGS:       -xarch=v9
-      XBS5_LPBIG_OFFBIG_LDFLAGS:      -xarch=v9
-      XBS5_LPBIG_OFFBIG_LINTFLAGS:    -xarch=v9
-      _XBS5_LP64_OFF64_CFLAGS:        -xarch=v9
-      _XBS5_LP64_OFF64_LDFLAGS:       -xarch=v9
-      _XBS5_LP64_OFF64_LINTFLAGS:     -xarch=v9
-      _XBS5_LPBIG_OFFBIG_CFLAGS:      -xarch=v9
-      _XBS5_LPBIG_OFFBIG_LDFLAGS:     -xarch=v9
-      _XBS5_LPBIG_OFFBIG_LINTFLAGS:   -xarch=v9
-
-  > > Now, what should we do, then?  Should -Duse64bits in a v9 box cause
-  > > Perl to compiled in v9 mode?  Or should we for compatibility stick
-  > > with 32 bit builds and let the people in the know to add the -xarch=v9
-  > > to ccflags (and ldflags?)?
-
-  > I think the second (explicit) mechanism should be the default.  Unless
-  > you want to allocate more than ~ 4Gb of memory inside Perl, you don't
-  > need Perl to be a 64-bit app.  Put it this way, on a machine running
-  > Solaris 8, there are 463 executables under /usr/bin, but only 15 of
-  > those require 64 bit versions - mainly because they invade the kernel
-  > address space, e.g. adb, kgmon etc.  Certainly we don't recommend users
-  > to build 64 bit apps unless they need the address space.

+I installed a new version of module X but CPAN keeps saying,
+I have the old version installed
+
+Most probably you B<do> have the old version installed. This can
+happen if a module installs itself into a different directory in the
+@INC path than it was previously installed. This is not really a
+CPAN.pm problem, you would have the same problem when installing the
+module manually. The easiest way to prevent this behaviour is to add
+the argument C<UNINST=1> to the C<make install> call, and that is why
+many people add this argument permanently by configuring
+
+  o conf make_install_arg UNINST=1
+
+=item 2)
+
+So why is UNINST=1 not the default?
+
+Because there are people who have their precise expectations about who
+may install where in the @INC path and who uses which @INC array. In
+fine tuned environments C<UNINST=1> can cause damage.
+
+=item 3)
+
+I want to clean up my mess, and install a new perl along with
+all modules I have. How do I go about it?
+
+Run the autobundle command for your old perl and optionally rename the
+resulting bundle file (e.g. Bundle/mybundle.pm), install the new perl
+with the Configure option prefix, e.g.
+
+    ./Configure -Dprefix=/usr/local/perl-5.6.78.9
+
+Install the bundle file you produced in the first step with something like
+
+    cpan> install Bundle::mybundle
+
+and you're done.
+
+=item 4)
+
+When I install bundles or multiple modules with one command
+there is too much output to keep track of.
+
+You may want to configure something like
+
+  o conf make_arg "| tee -ai /root/.cpan/logs/make.out"
+  o conf make_install_arg "| tee -ai /root/.cpan/logs/make_install.out"
+
+so that STDOUT is captured in a file for later inspection.
+
+
+=item 5)
+
+I am not root, how can I install a module in a personal directory?
+
+You will most probably like something like this:
+
+  o conf makepl_arg "LIB=~/myperl/lib \
+                    INSTALLMAN1DIR=~/myperl/man/man1 \
+                    INSTALLMAN3DIR=~/myperl/man/man3"
+  install Sybase::Sybperl
+
+You can make this setting permanent like all C<o conf> settings with
+C<o conf commit>.
+
+You will have to add ~/myperl/man to the MANPATH environment variable
+and also tell your perl programs to look into ~/myperl/lib, e.g. by
+including
+
+  use lib "$ENV{HOME}/myperl/lib";
+
+or setting the PERL5LIB environment variable.
+
+Another thing you should bear in mind is that the UNINST parameter
+should never be set if you are not root.

+
+I installed a Bundle and had a couple of fails. When I
+retried, everything resolved nicely. Can this be fixed to work
+on first try?
+
+The reason for this is that CPAN does not know the dependencies of all
+modules when it starts out. To decide about the additional items to
+install, it just uses data found in the generated Makefile. An
+undetected missing piece breaks the process. But it may well be that
+your Bundle installs some prerequisite later than some depending item
+and thus your second try is able to resolve everything. Please note,
+CPAN.pm does not know the dependency tree in advance and cannot sort
+the queue of things to install in a topologically correct order. It
+resolves perfectly well IFF all modules declare the prerequisites
+correctly with the PREREQ_PM attribute to MakeMaker. For bundles which
+fail and you need to install often, it is recommended sort the Bundle
+definition file manually. It is planned to improve the metadata
+situation for dependencies on CPAN in general, but this will still
+take some time.
+

+When I run CPAN's shell, I get error msg about line 1 to 4,

+
+Some versions of readline are picky about capitalization in the
+/etc/inputrc file and specifically RedHat 6.2 comes with a
+/etc/inputrc that contains the word C<on> in lowercase. Change the
+occurrences of C<on> to C<On> and the bug should disappear.
+
+=item 10)
+
+Some authors have strange characters in their names.
+
+Internally CPAN.pm uses the UTF-8 charset. If your terminal is
+expecting ISO-8859-1 charset, a converter can be activated by setting
+term_is_latin to a true value in your config file. One way of doing so
+would be

+    cpan> ! $CPAN::Config->{term_is_latin}=1
+
+Extended support for converters will be made available as soon as perl

 =head1 DESCRIPTION
 
+This module provides functions for determining the pathname of the
+current working directory.  By default, it exports the functions
+cwd(), getcwd(), fastcwd(), and fastgetcwd() into the caller's
+namespace.  Each of these functions are called without arguments and
+return the absolute path of the current working directory.  It is
+recommended that cwd (or another *cwd() function) be used in I<all>
+code to ensure portability.

+The cwd() is the most natural and safe form for the current
+architecture. For most systems it is identical to `pwd` (but without
+the trailing line terminator).

 The getcwd() function re-implements the getcwd(3) (or getwd(3)) functions
 in Perl.

+    GetOptions("foo|f!" => \$foo);
+
+Note that older Getopt::Long versions did not issue a warning, because

+=head1 DESCRIPTION
 
-When words that are longer than $columns are encountered, they
-are broken up.  Previous versions of wrap() die()ed instead.
-To restore the old (dying) behavior, set $Text::Wrap::huge to
-'die'.
+Text::Wrap::wrap() is a very simple paragraph formatter.  It formats a
+single paragraph at a time by breaking lines at word boundries.
+Indentation is controlled for the first line (C<$initial_tab>) and
+all subsquent lines (C<$subsequent_tab>) independently.  Please note: 
+C<$initial_tab> and C<$subsequent_tab> are the literal strings that will
+be used: it is unlikley you would want to pass in a number.
+
+Lines are wrapped at C<$Text::Wrap::columns> columns.  C<$Text::Wrap::columns>
+should be set to the full width of your output device.  In fact,
+every resulting line will have length of no more than C<$columns - 1>.  
+
+Beginner note: In example 2, above C<$columns> is imported into
+the local namespace, and set locally.  In example 3,
+C<$Text::Wrap::columns> is set in its own namespace without importing it.
+
+When words that are longer than C<$columns> are encountered, they
+are broken up.  C<wrap()> adds a C<"\n"> at column C<$columns>.
+This behavior can be overridden by setting C<$huge> to
+'die' or to 'overflow'.  When set to 'die', large words will cause
+C<die()> to be called.  When set to 'overflow', large words will be
+left intact.  
 
 Text::Wrap::fill() is a simple multi-paragraph formatter.  It formats
 each paragraph separately and then joins them together when it's done.  It
-will destroy any whitespace in the original text.  It breaks text into
+will destory any whitespace in the original text.  It breaks text into
 paragraphs by looking for whitespace after a newline.  In other respects
 it acts like wrap().
 
+When called in list context, C<wrap()> will return a list of lines and 
+C<fill()> will return a list of paragraphs.

+Historical notes: Older versions of C<wrap()> and C<fill()> always 
+returned strings.  Also, 'die' used to be the default value of
+C<$huge>.  Now, 'wrap' is the default value.

-This module provides the ability to use references as hash keys if
-you first C<tie> the hash variable to this module.
+This module provides the ability to use references as hash keys if you
+first C<tie> the hash variable to this module.  Normally, only the
+keys of the tied hash itself are preserved as references; to use
+references as keys in hashes-of-hashes, use Tie::RefHash::Nestable,
+included as part of Tie::RefHash.
 
 It is implemented using the standard perl TIEHASH interface.  Please
 see the C<tie> entry in perlfunc(1) and perltie(1) for more information.
 
+The Nestable version works by looking for hash references being stored
+and converting them to tied hashes so that they too can have
+references as keys.  This will happen without warning whenever you
+store a reference to one of your own hashes in the tied hash.

+-(2**63) .. (2**63-1) on 64-bit architectures.  For example, this code

-    $z = -1.5;
-
-you'll be left with C<$x == 1.5>, C<$y == 2> and C<$z == -1>.  The $z

+Note that $x is still printed as having its true non-integer value of
+5.8 since it wasn't operated on.  And note too the wrap-around from the
+largest positive integer to the largest negative one.   Also, arguments
+passed to functions and the values returned by them are B<not> affected
+by C<use integer;>.  E.g.,
+

+    $, = ", ";
+    print sin(.5), cos(.5), atan2(1,2), sqrt(2), rand(10);
+
+will give the same result with or without C<use integer;>  The power
+operator C<**> is also not affected, so that 2 ** .5 is always the
+square root of 2.  Now, it so happens that the pre- and post- increment
+and decrement operators, ++ and --, are not affected by C<use integer;>
+either.  Some may rightly consider this to be a bug -- but at least it's
+a long-standing one.
+
+Finally, C<use integer;> also has an additional affect on the bitwise
+operators.  Normally, the operands and results are treated as
+B<unsigned> integers, but with C<use integer;> the operands and results
+are B<signed>.  This means, among other things, that ~0 is -1, and -2 &
+-5 is -6.
+
+Internally, native integer arithmetic (as provided by your C compiler)

+but wasn't tickled by base.pm in those releases.
+
+=item Memory leaks
+
+Various cases of memory leaks and attempts to access uninitialized memory
+have been cured.  See L</"Known Problems"> below for further issues.
+
+=item Numeric conversions
+
+Numeric conversions did not recognize changes in the string value
+properly in certain circumstances.
+
+In other situations, large unsigned numbers (those above 2**31) could
+sometimes lose their unsignedness, causing bogus results in arithmetic
+operations.
+
+Integer modulus on large unsigned integers sometimes returned
+incorrect values.
+
+Perl 5.6.0 generated "not a number" warnings on certain conversions where
+previous versions didn't.
+
+These problems have all been rectified.
+
+Infinity is now recognized as a number.
+
+=item qw(a\\b)
+
+In Perl 5.6.0, qw(a\\b) produced a string with two backslashes instead
+of one, in a departure from the behavior in previous versions.  The
+older behavior has been reinstated.  
+
+=item caller()
+
+caller() could cause core dumps in certain situations.  Carp was sometimes
+affected by this problem.
+
+=item Bugs in regular expressions
+
+Pattern matches on overloaded values are now handled correctly.
+
+Perl 5.6.0 parsed m/\x{ab}/ incorrectly, leading to spurious warnings.
+This has been corrected.
+
+The RE engine found in Perl 5.6.0 accidentally pessimised certain kinds
+of simple pattern matches.  These are now handled better.
+
+Regular expression debug output (whether through C<use re 'debug'>
+or via C<-Dr>) now looks better.
+
+Multi-line matches like C<"a\nxb\n" =~ /(?!\A)x/m> were flawed.  The
+bug has been fixed.
+
+Use of $& could trigger a core dump under some situations.  This
+is now avoided.
+
+Match variables $1 et al., weren't being unset when a pattern match
+was backtracking, and the anomaly showed up inside C</...(?{ ... }).../>
+etc.  These variables are now tracked correctly.
+
+pos() did not return the correct value within s///ge in earlier
+versions.  This is now handled correctly.
+
+=item "slurp" mode
+
+readline() on files opened in "slurp" mode could return an extra "" at
+the end in certain situations.  This has been corrected.
+
+=item Autovivification of symbolic references to special variables
+
+Autovivification of symbolic references of special variables described
+in L<perlvar> (as in C<${$num}>) was accidentally disabled.  This works
+again now.
+
+=item Lexical warnings 
+
+Lexical warnings now propagate correctly into C<eval "...">.
+
+C<use warnings qw(FATAL all)> did not work as intended.  This has been
+corrected.
+
+Lexical warnings could leak into other scopes in some situations.
+This is now fixed.
+
+warnings::enabled() now reports the state of $^W correctly if the caller
+isn't using lexical warnings.
+
+=item Spurious warnings and errors
+
+Perl 5.6.0 could emit spurious warnings about redefinition of dl_error()
+when statically building extensions into perl.  This has been corrected.
+
+"our" variables could result in bogus "Variable will not stay shared"
+warnings.  This is now fixed.
+
+"our" variables of the same name declared in two sibling blocks
+resulted in bogus warnings about "redeclaration" of the variables.
+The problem has been corrected.
+
+=item glob()
+
+Compatibility of the builtin glob() with old csh-based glob has been
+improved with the addition of GLOB_ALPHASORT option.  See C<File::Glob>.
+
+File::Glob::glob() has been renamed to File::Glob::bsd_glob()
+because the name clashes with the builtin glob().  The older
+name is still available for compatibility, but is deprecated.
+
+Spurious syntax errors generated in certain situations, when glob()
+caused File::Glob to be loaded for the first time, have been fixed.
+
+=item Tainting
+
+Some cases of inconsistent taint propagation (such as within hash
+values) have been fixed.
+
+The tainting behavior of sprintf() has been rationalized.  It does
+not taint the result of floating point formats anymore, making the
+behavior consistent with that of string interpolation.
+
+=item sort()
+
+Arguments to sort() weren't being provided the right wantarray() context.
+The comparison block is now run in scalar context, and the arguments to
+be sorted are always provided list context.
+
+sort() is also fully reentrant, in the sense that the sort function
+can itself call sort().  This did not work reliably in previous releases.
+
+=item #line directives
+
+#line directives now work correctly when they appear at the very
+beginning of C<eval "...">.
+
+=item Subroutine prototypes
+
+The (\&) prototype now works properly.
+
+=item map()
+
+map() could get pathologically slow when the result list it generates
+is larger than the source list.  The performance has been improved for
+common scenarios.
+
+=item Debugger
+
+Debugger exit code now reflects the script exit code.
+
+Condition C<"0"> in breakpoints is now treated correctly.
+
+The C<d> command now checks the line number.
+
+C<$.> is no longer corrupted by the debugger.
+
+All debugger output now correctly goes to the socket if RemotePort
+is set.
+
+=item PERL5OPT
+
+PERL5OPT can be set to more than one switch group.  Previously,
+it used to be limited to one group of options only.
+
+=item chop()
+
+chop(@list) in list context returned the characters chopped in reverse
+order.  This has been reversed to be in the right order.
+
+=item Unicode support
+
+Unicode support has seen a large number of incremental improvements,
+but continues to be highly experimental.  It is not expected to be
+fully supported in the 5.6.x maintenance releases.
+
+substr(), join(), repeat(), reverse(), quotemeta() and string
+concatenation were all handling Unicode strings incorrectly in
+Perl 5.6.0.  This has been corrected.
+
+Support for C<tr///CU> and C<tr///UC> etc., have been removed since
+we realized the interface is broken.  For similar functionality,
+see L<perlfunc/pack>.
+
+The Unicode Character Database has been updated to version 3.0.1
+with additions made available to the public as of August 30, 2000.
+
+The Unicode character classes \p{Blank} and \p{SpacePerl} have been
+added.  "Blank" is like C isblank(), that is, it contains only
+"horizontal whitespace" (the space character is, the newline isn't),
+and the "SpacePerl" is the Unicode equivalent of C<\s> (\p{Space}
+isn't, since that includes the vertical tabulator character, whereas
+C<\s> doesn't.)
+
+If you are experimenting with Unicode support in perl, the development
+versions of Perl may have more to offer.  In particular, I/O layers

+=item 64-bit support
+
+Support for 64-bit platforms has been improved, but continues to be
+experimental.  The level of support varies greatly among platforms.
+
+=item Compiler
+
+The B Compiler and its various backends have had many incremental
+improvements, but they continue to remain highly experimental.  Use in
+production environments is discouraged.
+
+The perlcc tool has been rewritten so that the user interface is much
+more like that of a C compiler.
+
+The perlbc tools has been removed.  Use C<perlcc -B> instead.
+
+=item Lvalue subroutines
+
+There have been various bugfixes to support lvalue subroutines better.
+However, the feature still remains experimental.

+
+Arrays are now always interpolated in double-quotish strings.  Previously,
+C<"foo@bar.com"> used to be a fatal error at compile time, if an array
+C<@bar> was not used or declared.  This transitional behavior was
+intended to help migrate perl4 code, and is deemed to be no longer useful.

+(W misc) The pattern match (//), substitution (s///), and

 =head1 Embedding Perl under Win32
 
-At the time of this writing (5.004), there are two versions of Perl
-which run under Win32.  (The two versions are merging in 5.005.)
-Interfacing to ActiveState's Perl library is quite different from the
-examples in this documentation, as significant changes were made to
-the internal Perl API.  However, it is possible to embed ActiveState's
-Perl runtime.  For details, see the Perl for Win32 FAQ at
-http://www.perl.com/CPAN/doc/FAQs/win32/perlwin32faq.html.
-
-With the "official" Perl version 5.004 or higher, all the examples
-within this documentation will compile and run untouched, although
-the build process is slightly different between Unix and Win32.  
+In general, all of the source code shown here should work unmodified under
+Windows.
 
-For starters, backticks don't work under the Win32 native command shell.
+However, there are some caveats about the command-line examples shown.

+used term for Chip Salzenberg's project to rewrite Perl in C++ named

+Perl5, in mind.

+If you have a desire to help in the crusade to make Perl a better place

 =head2 How do I decode or create those %-encodings on the web?
 
-Here's an example of decoding:
 
-    $string = "http://altavista.digital.com/cgi-bin/query?pg=q&what=news&fmt=.&q=%2Bcgi-bin+%2Bperl.exe";
-    $string =~ s/%([a-fA-F0-9]{2})/chr(hex($1))/ge;
+If you are writing a CGI script, you should be using the CGI.pm module
+that comes with perl, or some other equivalent module.  The CGI module
+automatically decodes queries for you, and provides an escape()
+function to handle encoding.
 
-Encoding is a bit harder, because you can't just blindly change
-all the non-alphanumunder character (C<\W>) into their hex escapes.
-It's important that characters with special meaning like C</> and C<?>
-I<not> be translated.  Probably the easiest way to get this right is
-to avoid reinventing the wheel and just use the URI::Escape module,
-available from CPAN.
+
+The best source of detailed information on URI encoding is RFC 2396.
+Basically, the following substitutions do it:
+
+    s/([^\w()'*~!.-])/sprintf '%%%02x', $1/eg;   # encode
+
+    s/%([A-Fa-f\d]{2})/chr hex $1/eg;            # decode
+
+However, you should only apply them to individual URI components, not
+the entire URI, otherwise you'll lose information and generally mess
+things up.  If that didn't explain it, don't worry.  Just go read
+section 2 of the RFC, it's probably the best explanation there is.
+
+RFC 2396 also contains a lot of other useful information, including a
+regexp for breaking any arbitrary URI into components (Appendix B).

+=head2 Offsets
+
+Perl provides the function C<sv_chop> to efficiently remove characters
+from the beginning of a string; you give it an SV and a pointer to
+somewhere inside the the PV, and it discards everything before the
+pointer. The efficiency comes by means of a little hack: instead of
+actually removing the characters, C<sv_chop> sets the flag C<OOK>
+(offset OK) to signal to other functions that the offset hack is in
+effect, and it puts the number of bytes chopped off into the IV field
+of the SV. It then moves the PV pointer (called C<SvPVX>) forward that
+many bytes, and adjusts C<SvCUR> and C<SvLEN>. 
+
+Hence, at this point, the start of the buffer that we allocated lives
+at C<SvPVX(sv) - SvIV(sv)> in memory and the PV pointer is pointing
+into the middle of this allocated storage.
+
+This is best demonstrated by example:
+
+  % ./perl -Ilib -MDevel::Peek -le '$a="12345"; $a=~s/.//; Dump($a)'
+  SV = PVIV(0x8128450) at 0x81340f0
+    REFCNT = 1
+    FLAGS = (POK,OOK,pPOK)
+    IV = 1  (OFFSET)
+    PV = 0x8135781 ( "1" . ) "2345"\0
+    CUR = 4
+    LEN = 5
+
+Here the number of bytes chopped off (1) is put into IV, and
+C<Devel::Peek::Dump> helpfully reminds us that this is an offset. The
+portion of the string between the "real" and the "fake" beginnings is
+shown in parentheses, and the values of C<SvCUR> and C<SvLEN> reflect
+the fake beginning, not the real one.
+
+Something similar to the offset hack is perfomed on AVs to enable
+efficient shifting and splicing off the beginning of the array; while
+C<AvARRAY> points to the first element in the array that is visible from
+Perl, C<AvALLOC> points to the real start of the C array. These are
+usually the same, but a C<shift> operation can be carried out by
+increasing C<AvARRAY> by one and decreasing C<AvFILL> and C<AvLEN>.
+Again, the location of the real start of the C array only comes into
+play when freeing the array. See C<av_shift> in F<av.c>.

+All of Perl's internal functions which will be exposed to the outside
+world are be prefixed by C<Perl_> so that they will not conflict with XS
+functions or functions used in a program in which Perl is embedded.
+Similarly, all global variables begin with C<PL_>. (By convention,
+static functions start with C<S_>)
+
+Inside the Perl core, you can get at the functions either with or
+without the C<Perl_> prefix, thanks to a bunch of defines that live in
+F<embed.h>. This header file is generated automatically from
+F<embed.pl>. F<embed.pl> also creates the prototyping header files for
+the internal functions, generates the documentation and a lot of other
+bits and pieces. It's important that when you add a new function to the
+core or change an existing one, you change the data in the table at the
+end of F<embed.pl> as well. Here's a sample entry from that table:
+
+    Apd |SV**   |av_fetch   |AV* ar|I32 key|I32 lval
+
+The second column is the return type, the third column the name. Columns
+after that are the arguments. The first column is a set of flags:
+
+=over 3
+
+=item A
+
+This function is a part of the public API.
+
+=item p
+
+This function has a C<Perl_> prefix; ie, it is defined as C<Perl_av_fetch>
+
+=item d
+
+This function has documentation using the C<apidoc> feature which we'll
+look at in a second.
+
+=back
+
+Other available flags are:
+
+=over 3
+
+=item s
+
+This is a static function and is defined as C<S_whatever>, and usually
+called within the sources as C<whatever(...)>.
+
+=item n
+
+This does not use C<aTHX_> and C<pTHX> to pass interpreter context. (See
+L<perlguts/Background and PERL_IMPLICIT_CONTEXT>.)
+
+=item r
+
+This function never returns; C<croak>, C<exit> and friends.
+
+=item f
+
+This function takes a variable number of arguments, C<printf> style.
+The argument list should end with C<...>, like this:
+
+    Afprd   |void   |croak          |const char* pat|...
+
+=item M
+
+This function is part of the experimental development API, and may change 
+or disappear without notice.
+
+=item o
+
+This function should not have a compatibility macro to define, say,
+C<Perl_parse> to C<parse>. It must be called as C<Perl_parse>.
+
+=item j
+
+This function is not a member of C<CPerlObj>. If you don't know
+what this means, don't use it.
+
+=item x
+
+This function isn't exported out of the Perl core.
+
+=back
+
+If you edit F<embed.pl>, you will need to run C<make regen_headers> to
+force a rebuild of F<embed.h> and other auto-generated files.
+
+=head2 Formatted Printing of IVs, UVs, and NVs
+
+If you are printing IVs, UVs, or NVS instead of the stdio(3) style
+formatting codes like C<%d>, C<%ld>, C<%f>, you should use the
+following macros for portability
+
+        IVdf            IV in decimal
+        UVuf            UV in decimal
+        UVof            UV in octal
+        UVxf            UV in hexadecimal
+        NVef            NV %e-like
+        NVff            NV %f-like
+        NVgf            NV %g-like
+
+These will take care of 64-bit integers and long doubles.
+For example:
+
+        printf("IV is %"IVdf"\n", iv);
+
+The IVdf will expand to whatever is the correct format for the IVs.
+
+If you are printing addresses of pointers, use UVxf combined
+with PTR2UV(), do not use %lx or %p.
+
+=head2 Pointer-To-Integer and Integer-To-Pointer
+
+Because pointer size does not necessarily equal integer size,
+use the follow macros to do it right.
+
+        PTR2UV(pointer)
+        PTR2IV(pointer)
+        PTR2NV(pointer)
+        INT2PTR(pointertotype, integer)
+
+For example:
+
+        IV  iv = ...;
+        SV *sv = INT2PTR(SV*, iv);
+
+and
+
+        AV *av = ...;
+        UV  uv = PTR2UV(av);
+
+=head2 Source Documentation
+
+There's an effort going on to document the internal functions and
+automatically produce reference manuals from them - L<perlapi> is one
+such manual which details all the functions which are available to XS
+writers. L<perlintern> is the autogenerated manual for the functions
+which are not part of the API and are supposedly for internal use only.
+
+Source documentation is created by putting POD comments into the C
+source, like this:
+
+ /*
+ =for apidoc sv_setiv
+
+ Copies an integer into the given SV.  Does not handle 'set' magic.  See
+ C<sv_setiv_mg>.
+
+ =cut
+ */
+
+Please try and supply some documentation if you add functions to the
+Perl core.
+
+=head1 Unicode Support
+
+Perl 5.6.0 introduced Unicode support. It's important for porters and XS
+writers to understand this support and make sure that the code they
+write does not corrupt Unicode data.
+
+=head2 What B<is> Unicode, anyway?
+
+In the olden, less enlightened times, we all used to use ASCII. Most of
+us did, anyway. The big problem with ASCII is that it's American. Well,
+no, that's not actually the problem; the problem is that it's not
+particularly useful for people who don't use the Roman alphabet. What
+used to happen was that particular languages would stick their own
+alphabet in the upper range of the sequence, between 128 and 255. Of
+course, we then ended up with plenty of variants that weren't quite
+ASCII, and the whole point of it being a standard was lost.
+
+Worse still, if you've got a language like Chinese or
+Japanese that has hundreds or thousands of characters, then you really
+can't fit them into a mere 256, so they had to forget about ASCII
+altogether, and build their own systems using pairs of numbers to refer
+to one character.
+
+To fix this, some people formed Unicode, Inc. and
+produced a new character set containing all the characters you can
+possibly think of and more. There are several ways of representing these
+characters, and the one Perl uses is called UTF8. UTF8 uses
+a variable number of bytes to represent a character, instead of just
+one. You can learn more about Unicode at http://www.unicode.org/
+
+=head2 How can I recognise a UTF8 string?
+
+You can't. This is because UTF8 data is stored in bytes just like
+non-UTF8 data. The Unicode character 200, (C<0xC8> for you hex types)
+capital E with a grave accent, is represented by the two bytes
+C<v196.172>. Unfortunately, the non-Unicode string C<chr(196).chr(172)>
+has that byte sequence as well. So you can't tell just by looking - this
+is what makes Unicode input an interesting problem.
+
+The API function C<is_utf8_string> can help; it'll tell you if a string
+contains only valid UTF8 characters. However, it can't do the work for
+you. On a character-by-character basis, C<is_utf8_char> will tell you
+whether the current character in a string is valid UTF8.
+
+=head2 How does UTF8 represent Unicode characters?
+
+As mentioned above, UTF8 uses a variable number of bytes to store a
+character. Characters with values 1...128 are stored in one byte, just
+like good ol' ASCII. Character 129 is stored as C<v194.129>; this
+continues up to character 191, which is C<v194.191>. Now we've run out of
+bits (191 is binary C<10111111>) so we move on; 192 is C<v195.128>. And
+so it goes on, moving to three bytes at character 2048.
+
+Assuming you know you're dealing with a UTF8 string, you can find out
+how long the first character in it is with the C<UTF8SKIP> macro:
+
+    char *utf = "\305\233\340\240\201";
+    I32 len;
+
+    len = UTF8SKIP(utf); /* len is 2 here */
+    utf += len;
+    len = UTF8SKIP(utf); /* len is 3 here */
+
+Another way to skip over characters in a UTF8 string is to use
+C<utf8_hop>, which takes a string and a number of characters to skip
+over. You're on your own about bounds checking, though, so don't use it
+lightly.
+
+All bytes in a multi-byte UTF8 character will have the high bit set, so
+you can test if you need to do something special with this character
+like this:
+
+    UV uv;
+
+    if (utf & 0x80)
+        /* Must treat this as UTF8 */
+        uv = utf8_to_uv(utf);
+    else
+        /* OK to treat this character as a byte */
+        uv = *utf;
+
+You can also see in that example that we use C<utf8_to_uv> to get the
+value of the character; the inverse function C<uv_to_utf8> is available
+for putting a UV into UTF8:
+
+    if (uv > 0x80)
+        /* Must treat this as UTF8 */
+        utf8 = uv_to_utf8(utf8, uv);
+    else
+        /* OK to treat this character as a byte */
+        *utf8++ = uv;
+
+You B<must> convert characters to UVs using the above functions if
+you're ever in a situation where you have to match UTF8 and non-UTF8
+characters. You may not skip over UTF8 characters in this case. If you
+do this, you'll lose the ability to match hi-bit non-UTF8 characters;
+for instance, if your UTF8 string contains C<v196.172>, and you skip
+that character, you can never match a C<chr(200)> in a non-UTF8 string.
+So don't do that!
+
+=head2 How does Perl store UTF8 strings?
+
+Currently, Perl deals with Unicode strings and non-Unicode strings
+slightly differently. If a string has been identified as being UTF-8
+encoded, Perl will set a flag in the SV, C<SVf_UTF8>. You can check and
+manipulate this flag with the following macros:
+
+    SvUTF8(sv)
+    SvUTF8_on(sv)
+    SvUTF8_off(sv)
+
+This flag has an important effect on Perl's treatment of the string: if
+Unicode data is not properly distinguished, regular expressions,
+C<length>, C<substr> and other string handling operations will have
+undesirable results.
+
+The problem comes when you have, for instance, a string that isn't
+flagged is UTF8, and contains a byte sequence that could be UTF8 -
+especially when combining non-UTF8 and UTF8 strings.
+
+Never forget that the C<SVf_UTF8> flag is separate to the PV value; you
+need be sure you don't accidentally knock it off while you're
+manipulating SVs. More specifically, you cannot expect to do this:
+
+    SV *sv;
+    SV *nsv;
+    STRLEN len;
+    char *p;
+
+    p = SvPV(sv, len);
+    frobnicate(p);
+    nsv = newSVpvn(p, len);
+
+The C<char*> string does not tell you the whole story, and you can't
+copy or reconstruct an SV just by copying the string value. Check if the
+old SV has the UTF8 flag set, and act accordingly:
+
+    p = SvPV(sv, len);
+    frobnicate(p);
+    nsv = newSVpvn(p, len);
+    if (SvUTF8(sv))
+        SvUTF8_on(nsv);
+
+In fact, your C<frobnicate> function should be made aware of whether or
+not it's dealing with UTF8 data, so that it can handle the string
+appropriately.
+
+=head2 How do I convert a string to UTF8?
+
+If you're mixing UTF8 and non-UTF8 strings, you might find it necessary
+to upgrade one of the strings to UTF8. If you've got an SV, the easiest
+way to do this is:
+
+    sv_utf8_upgrade(sv);
+
+However, you must not do this, for example:
+
+    if (!SvUTF8(left))
+        sv_utf8_upgrade(left);
+
+If you do this in a binary operator, you will actually change one of the
+strings that came into the operator, and, while it shouldn't be noticeable
+by the end user, it can cause problems.
+
+Instead, C<bytes_to_utf8> will give you a UTF8-encoded B<copy> of its
+string argument. This is useful for having the data available for
+comparisons and so on, without harming the original SV. There's also
+C<utf8_to_bytes> to go the other way, but naturally, this will fail if
+the string contains any characters above 255 that can't be represented
+in a single byte.
+
+=head2 Is there anything else I need to know?
+
+Not really. Just remember these things:
+
+=over 3
+
+=item *
+
+There's no way to tell if a string is UTF8 or not. You can tell if an SV
+is UTF8 by looking at is C<SvUTF8> flag. Don't forget to set the flag if
+something should be UTF8. Treat the flag as part of the PV, even though
+it's not - if you pass on the PV to somewhere, pass on the flag too.
+
+=item *
+
+If a string is UTF8, B<always> use C<utf8_to_uv> to get at the value,
+unless C<!(*s & 0x80)> in which case you can use C<*s>.
+
+=item *
+
+When writing to a UTF8 string, B<always> use C<uv_to_utf8>, unless
+C<uv < 0x80> in which case you can use C<*s = uv>.
+
+=item *
+
+Mixing UTF8 and non-UTF8 strings is tricky. Use C<bytes_to_utf8> to get
+a new string which is UTF8 encoded. There are tricks you can use to
+delay deciding whether you need to use a UTF8 string until you get to a
+high character - C<HALF_UPGRADE> is one of those.

 Needless to say, the source code in perl-current is usually in a perpetual

+branch by FTP.)
+
+If you choose to keep in sync using rsync, there are two approaches
+to doing so:
+
+=over 4
+
+=item rsync'ing the source tree
+
+Presuming you are in the directory where your perl source resides
+and you have rsync installed and available, you can `upgrade' to
+the bleadperl using:
+
+ # rsync -avz rsync://ftp.linux.activestate.com/perl-current/ .
+
+This takes care of updating every single item in the source tree to
+the latest applied patch level, creating files that are new (to your
+distribution) and setting date/time stamps of existing files to
+reflect the bleadperl status.
+
+You can than check what patch was the latest that was applied by
+looking in the file B<.patch>, which will show the number of the
+latest patch.
+
+If you have more than one machine to keep in sync, and not all of
+them have access to the WAN (so you are not able to rsync all the
+source trees to the real source), there are some ways to get around
+this problem.
+
+=over 4
+
+=item Using rsync over the LAN
+
+Set up a local rsync server which makes the rsynced source tree
+available to the LAN and sync the other machines against this
+directory.
+
+From http://rsync.samba.org/README.html:
+
+   "Rsync uses rsh or ssh for communication. It does not need to be
+    setuid and requires no special privileges for installation.  It
+    does not require a inetd entry or a deamon.  You must, however,
+    have a working rsh or ssh system.  Using ssh is recommended for
+    its security features."
+
+=item Using pushing over the NFS
+
+Having the other systems mounted over the NFS, you can take an
+active pushing approach by checking the just updated tree against
+the other not-yet synced trees. An example would be
+
+  #!/usr/bin/perl -w
+
+  use strict;
+  use File::Copy;
+
+  my %MF = map {
+      m/(\S+)/;
+      $1 => [ (stat $1)[2, 7, 9] ];	# mode, size, mtime
+      } `cat MANIFEST`;
+
+  my %remote = map { $_ => "/$_/pro/3gl/CPAN/perl-5.7.1" } qw(host1 host2);
+
+  foreach my $host (keys %remote) {
+      unless (-d $remote{$host}) {
+	  print STDERR "Cannot Xsync for host $host\n";
+	  next;
+	  }
+      foreach my $file (keys %MF) {
+	  my $rfile = "$remote{$host}/$file";
+	  my ($mode, $size, $mtime) = (stat $rfile)[2, 7, 9];
+	  defined $size or ($mode, $size, $mtime) = (0, 0, 0);
+	  $size == $MF{$file}[1] && $mtime == $MF{$file}[2] and next;
+	  printf "%4s %-34s %8d %9d  %8d %9d\n",
+	      $host, $file, $MF{$file}[1], $MF{$file}[2], $size, $mtime;
+	  unlink $rfile;
+	  copy ($file, $rfile);
+	  utime time, $MF{$file}[2], $rfile;
+	  chmod $MF{$file}[0], $rfile;
+	  }
+      }
+
+though this is not perfect. It could be improved with checking
+file checksums before updating. Not all NFS systems support
+reliable utime support (when used over the NFS).
+
+=back
+
+=item rsync'ing the patches
+
+The source tree is maintained by the pumpking who applies patches to
+the files in the tree. These patches are either created by the
+pumpking himself using C<diff -c> after updating the file manually or
+by applying patches sent in by posters on the perl5-porters list.
+These patches are also saved and rsync'able, so you can apply them
+yourself to the source files.
+
+Presuming you are in a directory where your patches reside, you can
+get them in sync with
+
+ # rsync -avz rsync://ftp.linux.activestate.com/perl-current-diffs/ .
+
+This makes sure the latest available patch is downloaded to your
+patch directory.
+
+It's then up to you to apply these patches, using something like
+
+ # last=`ls -rt1 *.gz | tail -1`
+ # rsync -avz rsync://ftp.linux.activestate.com/perl-current-diffs/ .
+ # find . -name '*.gz' -newer $last -exec gzcat {} \; >blead.patch
+ # cd ../perl-current
+ # patch -p1 -N <../perl-current-diffs/blead.patch

+or, since this is only a hint towards how it works, use CPAN-patchaperl
+from Andreas König to have better control over the patching process.

+=head2 Why rsync the source tree
+
+=over 4
+
+=item It's easier
+
+Since you don't have to apply the patches yourself, you are sure all
+files in the source tree are in the right state.
+
+=item It's more recent
+
+According to Gurusamy Sarathy:
+
+   "... The rsync mirror is automatic and syncs with the repository
+    every five minutes.
+
+   "Updating the patch  area  still  requires  manual  intervention
+    (with all the goofiness that implies,  which you've noted)  and
+    is typically on a daily cycle.   Making this process  automatic
+    is on my tuit list, but don't ask me when."
+
+=item It's more reliable
+
+Well, since the patches are updated by hand, I don't have to say any
+more ... (see Sarathy's remark).
+
+=back
+
+=head2 Why rsync the patches
+
+=over 4
+
+=item It's easier
+
+If you have more than one machine that you want to keep in track with
+bleadperl, it's easier to rsync the patches only once and then apply
+them to all the source trees on the different machines.
+
+In case you try to keep in pace on 5 different machines, for which
+only one of them has access to the WAN, rsync'ing all the source
+trees should than be done 5 times over the NFS. Having
+rsync'ed the patches only once, I can apply them to all the source
+trees automatically. Need you say more ;-)
+
+=item It's a good reference
+
+If you do not only like to have the most recent development branch,
+but also like to B<fix> bugs, or extend features, you want to dive
+into the sources. If you are a seasoned perl core diver, you don't
+need no manuals, tips, roadmaps, perlguts.pod or other aids to find
+your way around. But if you are a starter, the patches may help you
+in finding where you should start and how to change the bits that
+bug you.
+
+The file B<Changes> is updated on occasions the pumpking sees as his
+own little sync points. On those occasions, he releases a tar-ball of
+the current source tree (i.e. perl@7582.tar.gz), which will be an
+excellent point to start with when choosing to use the 'rsync the
+patches' scheme. Starting with perl@7582, which means a set of source
+files on which the latest applied patch is number 7582, you apply all
+succeeding patches available from then on (7583, 7584, ...).
+
+You can use the patches later as a kind of search archive.
+
+=over 4
+
+=item Finding a start point
+
+If you want to fix/change the behaviour of function/feature Foo, just
+scan the patches for patches that mention Foo either in the subject,
+the comments, or the body of the fix. A good chance the patch shows
+you the files that are affected by that patch which are very likely
+to be the starting point of your journey into the guts of perl.
+
+=item Finding how to fix a bug
+
+If you've found I<where> the function/feature Foo misbehaves, but you
+don't know how to fix it (but you do know the change you want to
+make), you can, again, peruse the patches for similar changes and
+look how others apply the fix.
+
+=item Finding the source of misbehaviour
+
+When you keep in sync with bleadperl, the pumpking would love to
+I<see> that the community efforts realy work. So after each of his
+sync points, you are to 'make test' to check if everything is still
+in working order. If it is, you do 'make ok', which will send an OK
+report to perlbug@perl.org. (If you do not have access to a mailer
+from the system you just finished successfully 'make test', you can
+do 'make okfile', which creates the file C<perl.ok>, which you can
+than take to your favourite mailer and mail yourself).
+
+But of course, as always, things will not allways lead to a success
+path, and one or more test do not pass the 'make test'. Before
+sending in a bug report (using 'make nok' or 'make nokfile'), check
+the mailing list if someone else has reported the bug already and if
+so, confirm it by replying to that message. If not, you might want to
+trace the source of that misbehaviour B<before> sending in the bug,
+which will help all the other porters in finding the solution.
+
+Here the saved patches come in very handy. You can check the list of
+patches to see which patch changed what file and what change caused
+the misbehaviour. If you note that in the bug report, it saves the
+one trying to solve it, looking for that point.
+
+=back
+
+If searching the patches is too bothersome, you might consider using
+perl's bugtron to find more information about discussions and
+ramblings on posted bugs.

+=head2 Finding Your Way Around
+
+Perl maintenance can be split into a number of areas, and certain people
+(pumpkins) will have responsibility for each area. These areas sometimes
+correspond to files or directories in the source kit. Among the areas are:
+
+=over 3
+
+=item Core modules
+
+Modules shipped as part of the Perl core live in the F<lib/> and F<ext/>
+subdirectories: F<lib/> is for the pure-Perl modules, and F<ext/>
+contains the core XS modules.
+
+=item Documentation
+
+Documentation maintenance includes looking after everything in the
+F<pod/> directory, (as well as contributing new documentation) and
+the documentation to the modules in core.
+
+=item Configure
+
+The configure process is the way we make Perl portable across the
+myriad of operating systems it supports. Responsibility for the
+configure, build and installation process, as well as the overall
+portability of the core code rests with the configure pumpkin - others
+help out with individual operating systems.
+
+The files involved are the operating system directories, (F<win32/>,
+F<os2/>, F<vms/> and so on) the shell scripts which generate F<config.h>
+and F<Makefile>, as well as the metaconfig files which generate
+F<Configure>. (metaconfig isn't included in the core distribution.)
+
+=item Interpreter
+
+And of course, there's the core of the Perl interpreter itself. Let's
+have a look at that in a little more detail.
+
+=back
+
+Before we leave looking at the layout, though, don't forget that
+F<MANIFEST> contains not only the file names in the Perl distribution,
+but short descriptions of what's in them, too. For an overview of the
+important files, try this:
+
+    perl -lne 'print if /^[^\/]+\.[ch]\s+/' MANIFEST
+
+=head2 Elements of the interpreter
+
+The work of the interpreter has two main stages: compiling the code
+into the internal representation, or bytecode, and then executing it.
+L<perlguts/Compiled code> explains exactly how the compilation stage
+happens.
+
+Here is a short breakdown of perl's operation:
+
+=over 3
+
+=item Startup
+
+The action begins in F<perlmain.c>. (or F<miniperlmain.c> for miniperl)
+This is very high-level code, enough to fit on a single screen, and it
+resembles the code found in L<perlembed>; most of the real action takes
+place in F<perl.c>
+
+First, F<perlmain.c> allocates some memory and constructs a Perl
+interpreter:
+
+    1 PERL_SYS_INIT3(&argc,&argv,&env);
+    2
+    3 if (!PL_do_undump) {
+    4     my_perl = perl_alloc();
+    5     if (!my_perl)
+    6         exit(1);
+    7     perl_construct(my_perl);
+    8     PL_perl_destruct_level = 0;
+    9 }
+
+Line 1 is a macro, and its definition is dependent on your operating
+system. Line 3 references C<PL_do_undump>, a global variable - all
+global variables in Perl start with C<PL_>. This tells you whether the
+current running program was created with the C<-u> flag to perl and then
+F<undump>, which means it's going to be false in any sane context.
+
+Line 4 calls a function in F<perl.c> to allocate memory for a Perl
+interpreter. It's quite a simple function, and the guts of it looks like
+this:
+
+    my_perl = (PerlInterpreter*)PerlMem_malloc(sizeof(PerlInterpreter));
+
+Here you see an example of Perl's system abstraction, which we'll see
+later: C<PerlMem_malloc> is either your system's C<malloc>, or Perl's
+own C<malloc> as defined in F<malloc.c> if you selected that option at
+configure time.
+
+Next, in line 7, we construct the interpreter; this sets up all the
+special variables that Perl needs, the stacks, and so on.
+
+Now we pass Perl the command line options, and tell it to go:
+
+    exitstatus = perl_parse(my_perl, xs_init, argc, argv, (char **)NULL);
+    if (!exitstatus) {
+        exitstatus = perl_run(my_perl);
+    }
+
+
+C<perl_parse> is actually a wrapper around C<S_parse_body>, as defined
+in F<perl.c>, which processes the command line options, sets up any
+statically linked XS modules, opens the program and calls C<yyparse> to
+parse it.
+
+=item Parsing
+
+The aim of this stage is to take the Perl source, and turn it into an op
+tree. We'll see what one of those looks like later. Strictly speaking,
+there's three things going on here.
+
+C<yyparse>, the parser, lives in F<perly.c>, although you're better off
+reading the original YACC input in F<perly.y>. (Yes, Virginia, there
+B<is> a YACC grammar for Perl!) The job of the parser is to take your
+code and `understand' it, splitting it into sentences, deciding which
+operands go with which operators and so on.
+
+The parser is nobly assisted by the lexer, which chunks up your input
+into tokens, and decides what type of thing each token is: a variable
+name, an operator, a bareword, a subroutine, a core function, and so on.
+The main point of entry to the lexer is C<yylex>, and that and its
+associated routines can be found in F<toke.c>. Perl isn't much like
+other computer languages; it's highly context sensitive at times, it can
+be tricky to work out what sort of token something is, or where a token
+ends. As such, there's a lot of interplay between the tokeniser and the
+parser, which can get pretty frightening if you're not used to it.
+
+As the parser understands a Perl program, it builds up a tree of
+operations for the interpreter to perform during execution. The routines
+which construct and link together the various operations are to be found
+in F<op.c>, and will be examined later.
+
+=item Optimization
+
+Now the parsing stage is complete, and the finished tree represents
+the operations that the Perl interpreter needs to perform to execute our
+program. Next, Perl does a dry run over the tree looking for
+optimisations: constant expressions such as C<3 + 4> will be computed
+now, and the optimizer will also see if any multiple operations can be
+replaced with a single one. For instance, to fetch the variable C<$foo>,
+instead of grabbing the glob C<*foo> and looking at the scalar
+component, the optimizer fiddles the op tree to use a function which
+directly looks up the scalar in question. The main optimizer is C<peep>
+in F<op.c>, and many ops have their own optimizing functions.
+
+=item Running
+
+Now we're finally ready to go: we have compiled Perl byte code, and all
+that's left to do is run it. The actual execution is done by the
+C<runops_standard> function in F<run.c>; more specifically, it's done by
+these three innocent looking lines:
+
+    while ((PL_op = CALL_FPTR(PL_op->op_ppaddr)(aTHX))) {
+        PERL_ASYNC_CHECK();
+    }
+
+You may be more comfortable with the Perl version of that:
+
+    PERL_ASYNC_CHECK() while $Perl::op = &{$Perl::op->{function}};
+
+Well, maybe not. Anyway, each op contains a function pointer, which
+stipulates the function which will actually carry out the operation.
+This function will return the next op in the sequence - this allows for
+things like C<if> which choose the next op dynamically at run time.
+The C<PERL_ASYNC_CHECK> makes sure that things like signals interrupt
+execution if required.
+
+The actual functions called are known as PP code, and they're spread
+between four files: F<pp_hot.c> contains the `hot' code, which is most
+often used and highly optimized, F<pp_sys.c> contains all the
+system-specific functions, F<pp_ctl.c> contains the functions which
+implement control structures (C<if>, C<while> and the like) and F<pp.c>
+contains everything else. These are, if you like, the C code for Perl's
+built-in functions and operators.
+
+=back
+
+=head2 Internal Variable Types
+
+You should by now have had a look at L<perlguts>, which tells you about
+Perl's internal variable types: SVs, HVs, AVs and the rest. If not, do
+that now.
+
+These variables are used not only to represent Perl-space variables, but
+also any constants in the code, as well as some structures completely
+internal to Perl. The symbol table, for instance, is an ordinary Perl
+hash. Your code is represented by an SV as it's read into the parser;
+any program files you call are opened via ordinary Perl filehandles, and
+so on.
+
+The core L<Devel::Peek|Devel::Peek> module lets us examine SVs from a
+Perl program. Let's see, for instance, how Perl treats the constant
+C<"hello">.
+
+      % perl -MDevel::Peek -e 'Dump("hello")'
+    1 SV = PV(0xa041450) at 0xa04ecbc
+    2   REFCNT = 1
+    3   FLAGS = (POK,READONLY,pPOK)
+    4   PV = 0xa0484e0 "hello"\0
+    5   CUR = 5
+    6   LEN = 6
+
+Reading C<Devel::Peek> output takes a bit of practise, so let's go
+through it line by line.
+
+Line 1 tells us we're looking at an SV which lives at C<0xa04ecbc> in
+memory. SVs themselves are very simple structures, but they contain a
+pointer to a more complex structure. In this case, it's a PV, a
+structure which holds a string value, at location C<0xa041450>.  Line 2
+is the reference count; there are no other references to this data, so
+it's 1.
+
+Line 3 are the flags for this SV - it's OK to use it as a PV, it's a
+read-only SV (because it's a constant) and the data is a PV internally.
+Next we've got the contents of the string, starting at location
+C<0xa0484e0>.
+
+Line 5 gives us the current length of the string - note that this does
+B<not> include the null terminator. Line 6 is not the length of the
+string, but the length of the currently allocated buffer; as the string
+grows, Perl automatically extends the available storage via a routine
+called C<SvGROW>.
+
+You can get at any of these quantities from C very easily; just add
+C<Sv> to the name of the field shown in the snippet, and you've got a
+macro which will return the value: C<SvCUR(sv)> returns the current
+length of the string, C<SvREFCOUNT(sv)> returns the reference count,
+C<SvPV(sv, len)> returns the string itself with its length, and so on.
+More macros to manipulate these properties can be found in L<perlguts>.
+
+Let's take an example of manipulating a PV, from C<sv_catpvn>, in F<sv.c>
+
+     1  void
+     2  Perl_sv_catpvn(pTHX_ register SV *sv, register const char *ptr, register STRLEN len)
+     3  {
+     4      STRLEN tlen;
+     5      char *junk;
+
+     6      junk = SvPV_force(sv, tlen);
+     7      SvGROW(sv, tlen + len + 1);
+     8      if (ptr == junk)
+     9          ptr = SvPVX(sv);
+    10      Move(ptr,SvPVX(sv)+tlen,len,char);
+    11      SvCUR(sv) += len;
+    12      *SvEND(sv) = '\0';
+    13      (void)SvPOK_only_UTF8(sv);          /* validate pointer */
+    14      SvTAINT(sv);
+    15  }
+
+This is a function which adds a string, C<ptr>, of length C<len> onto
+the end of the PV stored in C<sv>. The first thing we do in line 6 is
+make sure that the SV B<has> a valid PV, by calling the C<SvPV_force>
+macro to force a PV. As a side effect, C<tlen> gets set to the current
+value of the PV, and the PV itself is returned to C<junk>.
+
+In line 7, we make sure that the SV will have enough room to accommodate
+the old string, the new string and the null terminator. If C<LEN> isn't
+big enough, C<SvGROW> will reallocate space for us.
+
+Now, if C<junk> is the same as the string we're trying to add, we can
+grab the string directly from the SV; C<SvPVX> is the address of the PV
+in the SV.
+
+Line 10 does the actual catenation: the C<Move> macro moves a chunk of
+memory around: we move the string C<ptr> to the end of the PV - that's
+the start of the PV plus its current length. We're moving C<len> bytes
+of type C<char>. After doing so, we need to tell Perl we've extended the
+string, by altering C<CUR> to reflect the new length. C<SvEND> is a
+macro which gives us the end of the string, so that needs to be a
+C<"\0">.
+
+Line 13 manipulates the flags; since we've changed the PV, any IV or NV
+values will no longer be valid: if we have C<$a=10; $a.="6";> we don't
+want to use the old IV of 10. C<SvPOK_only_utf8> is a special UTF8-aware
+version of C<SvPOK_only>, a macro which turns off the IOK and NOK flags
+and turns on POK. The final C<SvTAINT> is a macro which launders tainted
+data if taint mode is turned on.
+
+AVs and HVs are more complicated, but SVs are by far the most common
+variable type being thrown around. Having seen something of how we
+manipulate these, let's go on and look at how the op tree is
+constructed.
+
+=head2 Op Trees
+
+First, what is the op tree, anyway? The op tree is the parsed
+representation of your program, as we saw in our section on parsing, and
+it's the sequence of operations that Perl goes through to execute your
+program, as we saw in L</Running>.
+
+An op is a fundamental operation that Perl can perform: all the built-in
+functions and operators are ops, and there are a series of ops which
+deal with concepts the interpreter needs internally - entering and
+leaving a block, ending a statement, fetching a variable, and so on.
+
+The op tree is connected in two ways: you can imagine that there are two
+"routes" through it, two orders in which you can traverse the tree.
+First, parse order reflects how the parser understood the code, and
+secondly, execution order tells perl what order to perform the
+operations in.
+
+The easiest way to examine the op tree is to stop Perl after it has
+finished parsing, and get it to dump out the tree. This is exactly what
+the compiler backends L<B::Terse|B::Terse> and L<B::Debug|B::Debug> do.
+
+Let's have a look at how Perl sees C<$a = $b + $c>:
+
+     % perl -MO=Terse -e '$a=$b+$c'
+     1  LISTOP (0x8179888) leave
+     2      OP (0x81798b0) enter
+     3      COP (0x8179850) nextstate
+     4      BINOP (0x8179828) sassign
+     5          BINOP (0x8179800) add [1]
+     6              UNOP (0x81796e0) null [15]
+     7                  SVOP (0x80fafe0) gvsv  GV (0x80fa4cc) *b
+     8              UNOP (0x81797e0) null [15]
+     9                  SVOP (0x8179700) gvsv  GV (0x80efeb0) *c
+    10          UNOP (0x816b4f0) null [15]
+    11              SVOP (0x816dcf0) gvsv  GV (0x80fa460) *a
+
+Let's start in the middle, at line 4. This is a BINOP, a binary
+operator, which is at location C<0x8179828>. The specific operator in
+question is C<sassign> - scalar assignment - and you can find the code
+which implements it in the function C<pp_sassign> in F<pp_hot.c>. As a
+binary operator, it has two children: the add operator, providing the
+result of C<$b+$c>, is uppermost on line 5, and the left hand side is on
+line 10.
+
+Line 10 is the null op: this does exactly nothing. What is that doing
+there? If you see the null op, it's a sign that something has been
+optimized away after parsing. As we mentioned in L</Optimization>,
+the optimization stage sometimes converts two operations into one, for
+example when fetching a scalar variable. When this happens, instead of
+rewriting the op tree and cleaning up the dangling pointers, it's easier
+just to replace the redundant operation with the null op. Originally,
+the tree would have looked like this:
+
+    10          SVOP (0x816b4f0) rv2sv [15]
+    11              SVOP (0x816dcf0) gv  GV (0x80fa460) *a
+
+That is, fetch the C<a> entry from the main symbol table, and then look
+at the scalar component of it: C<gvsv> (C<pp_gvsv> into F<pp_hot.c>)
+happens to do both these things.
+
+The right hand side, starting at line 5 is similar to what we've just
+seen: we have the C<add> op (C<pp_add> also in F<pp_hot.c>) add together
+two C<gvsv>s.
+
+Now, what's this about?
+
+     1  LISTOP (0x8179888) leave
+     2      OP (0x81798b0) enter
+     3      COP (0x8179850) nextstate
+
+C<enter> and C<leave> are scoping ops, and their job is to perform any
+housekeeping every time you enter and leave a block: lexical variables
+are tidied up, unreferenced variables are destroyed, and so on. Every
+program will have those first three lines: C<leave> is a list, and its
+children are all the statements in the block. Statements are delimited
+by C<nextstate>, so a block is a collection of C<nextstate> ops, with
+the ops to be performed for each statement being the children of
+C<nextstate>. C<enter> is a single op which functions as a marker.
+
+That's how Perl parsed the program, from top to bottom:
+
+                        Program
+                           |
+                       Statement
+                           |
+                           =
+                          / \
+                         /   \
+                        $a   +
+                            / \
+                          $b   $c
+
+However, it's impossible to B<perform> the operations in this order:
+you have to find the values of C<$b> and C<$c> before you add them
+together, for instance. So, the other thread that runs through the op
+tree is the execution order: each op has a field C<op_next> which points
+to the next op to be run, so following these pointers tells us how perl
+executes the code. We can traverse the tree in this order using
+the C<exec> option to C<B::Terse>:
+
+     % perl -MO=Terse,exec -e '$a=$b+$c'
+     1  OP (0x8179928) enter
+     2  COP (0x81798c8) nextstate
+     3  SVOP (0x81796c8) gvsv  GV (0x80fa4d4) *b
+     4  SVOP (0x8179798) gvsv  GV (0x80efeb0) *c
+     5  BINOP (0x8179878) add [1]
+     6  SVOP (0x816dd38) gvsv  GV (0x80fa468) *a
+     7  BINOP (0x81798a0) sassign
+     8  LISTOP (0x8179900) leave
+
+This probably makes more sense for a human: enter a block, start a
+statement. Get the values of C<$b> and C<$c>, and add them together.
+Find C<$a>, and assign one to the other. Then leave.
+
+The way Perl builds up these op trees in the parsing process can be
+unravelled by examining F<perly.y>, the YACC grammar. Let's take the
+piece we need to construct the tree for C<$a = $b + $c>
+
+    1 term    :   term ASSIGNOP term
+    2                { $$ = newASSIGNOP(OPf_STACKED, $1, $2, $3); }
+    3         |   term ADDOP term
+    4                { $$ = newBINOP($2, 0, scalar($1), scalar($3)); }
+
+If you're not used to reading BNF grammars, this is how it works: You're
+fed certain things by the tokeniser, which generally end up in upper
+case. Here, C<ADDOP>, is provided when the tokeniser sees C<+> in your
+code. C<ASSIGNOP> is provided when C<=> is used for assigning. These are
+`terminal symbols', because you can't get any simpler than them.
+
+The grammar, lines one and three of the snippet above, tells you how to
+build up more complex forms. These complex forms, `non-terminal symbols'
+are generally placed in lower case. C<term> here is a non-terminal
+symbol, representing a single expression.
+
+The grammar gives you the following rule: you can make the thing on the
+left of the colon if you see all the things on the right in sequence.
+This is called a "reduction", and the aim of parsing is to completely
+reduce the input. There are several different ways you can perform a
+reduction, separated by vertical bars: so, C<term> followed by C<=>
+followed by C<term> makes a C<term>, and C<term> followed by C<+>
+followed by C<term> can also make a C<term>.
+
+So, if you see two terms with an C<=> or C<+>, between them, you can
+turn them into a single expression. When you do this, you execute the
+code in the block on the next line: if you see C<=>, you'll do the code
+in line 2. If you see C<+>, you'll do the code in line 4. It's this code
+which contributes to the op tree.
+
+            |   term ADDOP term
+            { $$ = newBINOP($2, 0, scalar($1), scalar($3)); }
+
+What this does is creates a new binary op, and feeds it a number of
+variables. The variables refer to the tokens: C<$1> is the first token in
+the input, C<$2> the second, and so on - think regular expression
+backreferences. C<$$> is the op returned from this reduction. So, we
+call C<newBINOP> to create a new binary operator. The first parameter to
+C<newBINOP>, a function in F<op.c>, is the op type. It's an addition
+operator, so we want the type to be C<ADDOP>. We could specify this
+directly, but it's right there as the second token in the input, so we
+use C<$2>. The second parameter is the op's flags: 0 means `nothing
+special'. Then the things to add: the left and right hand side of our
+expression, in scalar context.
+
+=head2 Stacks
+
+When perl executes something like C<addop>, how does it pass on its
+results to the next op? The answer is, through the use of stacks. Perl
+has a number of stacks to store things it's currently working on, and
+we'll look at the three most important ones here.
+
+=over 3
+
+=item Argument stack
+
+Arguments are passed to PP code and returned from PP code using the
+argument stack, C<ST>. The typical way to handle arguments is to pop
+them off the stack, deal with them how you wish, and then push the result
+back onto the stack. This is how, for instance, the cosine operator
+works:
+
+      NV value;
+      value = POPn;
+      value = Perl_cos(value);
+      XPUSHn(value);
+
+We'll see a more tricky example of this when we consider Perl's macros
+below. C<POPn> gives you the NV (floating point value) of the top SV on
+the stack: the C<$x> in C<cos($x)>. Then we compute the cosine, and push
+the result back as an NV. The C<X> in C<XPUSHn> means that the stack
+should be extended if necessary - it can't be necessary here, because we
+know there's room for one more item on the stack, since we've just
+removed one! The C<XPUSH*> macros at least guarantee safety.
+
+Alternatively, you can fiddle with the stack directly: C<SP> gives you
+the first element in your portion of the stack, and C<TOP*> gives you
+the top SV/IV/NV/etc. on the stack. So, for instance, to do unary
+negation of an integer:
+
+     SETi(-TOPi);
+
+Just set the integer value of the top stack entry to its negation.
+
+Argument stack manipulation in the core is exactly the same as it is in
+XSUBs - see L<perlxstut>, L<perlxs> and L<perlguts> for a longer
+description of the macros used in stack manipulation.
+
+=item Mark stack
+
+I say `your portion of the stack' above because PP code doesn't
+necessarily get the whole stack to itself: if your function calls
+another function, you'll only want to expose the arguments aimed for the
+called function, and not (necessarily) let it get at your own data. The
+way we do this is to have a `virtual' bottom-of-stack, exposed to each
+function. The mark stack keeps bookmarks to locations in the argument
+stack usable by each function. For instance, when dealing with a tied
+variable, (internally, something with `P' magic) Perl has to call
+methods for accesses to the tied variables. However, we need to separate
+the arguments exposed to the method to the argument exposed to the
+original function - the store or fetch or whatever it may be. Here's how
+the tied C<push> is implemented; see C<av_push> in F<av.c>:
+
+     1	PUSHMARK(SP);
+     2	EXTEND(SP,2);
+     3	PUSHs(SvTIED_obj((SV*)av, mg));
+     4	PUSHs(val);
+     5	PUTBACK;
+     6	ENTER;
+     7	call_method("PUSH", G_SCALAR|G_DISCARD);
+     8	LEAVE;
+     9	POPSTACK;
+
+The lines which concern the mark stack are the first, fifth and last
+lines: they save away, restore and remove the current position of the
+argument stack. 
+
+Let's examine the whole implementation, for practice:
+
+     1	PUSHMARK(SP);
+
+Push the current state of the stack pointer onto the mark stack. This is
+so that when we've finished adding items to the argument stack, Perl
+knows how many things we've added recently.
+
+     2	EXTEND(SP,2);
+     3	PUSHs(SvTIED_obj((SV*)av, mg));
+     4	PUSHs(val);
+
+We're going to add two more items onto the argument stack: when you have
+a tied array, the C<PUSH> subroutine receives the object and the value
+to be pushed, and that's exactly what we have here - the tied object,
+retrieved with C<SvTIED_obj>, and the value, the SV C<val>.
+
+     5	PUTBACK;
+
+Next we tell Perl to make the change to the global stack pointer: C<dSP>
+only gave us a local copy, not a reference to the global.
+
+     6	ENTER;
+     7	call_method("PUSH", G_SCALAR|G_DISCARD);
+     8	LEAVE;
+
+C<ENTER> and C<LEAVE> localise a block of code - they make sure that all
+variables are tidied up, everything that has been localised gets
+its previous value returned, and so on. Think of them as the C<{> and
+C<}> of a Perl block.
+
+To actually do the magic method call, we have to call a subroutine in
+Perl space: C<call_method> takes care of that, and it's described in
+L<perlcall>. We call the C<PUSH> method in scalar context, and we're
+going to discard its return value.
+
+     9	POPSTACK;
+
+Finally, we remove the value we placed on the mark stack, since we
+don't need it any more.
+
+=item Save stack
+
+C doesn't have a concept of local scope, so perl provides one. We've
+seen that C<ENTER> and C<LEAVE> are used as scoping braces; the save
+stack implements the C equivalent of, for example:
+
+    {
+        local $foo = 42;
+        ...
+    }
+
+See L<perlguts/Localising Changes> for how to use the save stack.
+
+=back
+
+=head2 Millions of Macros
+
+One thing you'll notice about the Perl source is that it's full of
+macros. Some have called the pervasive use of macros the hardest thing
+to understand, others find it adds to clarity. Let's take an example,
+the code which implements the addition operator:
+
+   1  PP(pp_add)
+   2  {
+   3      dSP; dATARGET; tryAMAGICbin(add,opASSIGN);
+   4      {
+   5        dPOPTOPnnrl_ul;
+   6        SETn( left + right );
+   7        RETURN;
+   8      }
+   9  }
+
+Every line here (apart from the braces, of course) contains a macro. The
+first line sets up the function declaration as Perl expects for PP code;
+line 3 sets up variable declarations for the argument stack and the
+target, the return value of the operation. Finally, it tries to see if
+the addition operation is overloaded; if so, the appropriate subroutine
+is called.
+
+Line 5 is another variable declaration - all variable declarations start
+with C<d> - which pops from the top of the argument stack two NVs (hence
+C<nn>) and puts them into the variables C<right> and C<left>, hence the
+C<rl>. These are the two operands to the addition operator. Next, we
+call C<SETn> to set the NV of the return value to the result of adding
+the two values. This done, we return - the C<RETURN> macro makes sure
+that our return value is properly handled, and we pass the next operator
+to run back to the main run loop.
+
+Most of these macros are explained in L<perlapi>, and some of the more
+important ones are explained in L<perlxs> as well. Pay special attention
+to L<perlguts/Background and PERL_IMPLICIT_CONTEXT> for information on
+the C<[pad]THX_?> macros.
+
+
+=head2 Poking at Perl
+
+To really poke around with Perl, you'll probably want to build Perl for
+debugging, like this:
+
+    ./Configure -d -D optimize=-g
+    make
+
+C<-g> is a flag to the C compiler to have it produce debugging
+information which will allow us to step through a running program.
+F<Configure> will also turn on the C<DEBUGGING> compilation symbol which
+enables all the internal debugging code in Perl. There are a whole bunch
+of things you can debug with this: L<perlrun> lists them all, and the
+best way to find out about them is to play about with them. The most
+useful options are probably
+
+    l  Context (loop) stack processing
+    t  Trace execution
+    o  Method and overloading resolution
+    c  String/numeric conversions
+
+Some of the functionality of the debugging code can be achieved using XS
+modules.
+
+    -Dr => use re 'debug'
+    -Dx => use O 'Debug'
+
+=head2 Using a source-level debugger
+
+If the debugging output of C<-D> doesn't help you, it's time to step
+through perl's execution with a source-level debugger.
+
+=over 3
+
+=item *
+
+We'll use C<gdb> for our examples here; the principles will apply to any
+debugger, but check the manual of the one you're using.
+
+=back
+
+To fire up the debugger, type
+
+    gdb ./perl
+
+You'll want to do that in your Perl source tree so the debugger can read
+the source code. You should see the copyright message, followed by the
+prompt.
+
+    (gdb)
+
+C<help> will get you into the documentation, but here are the most
+useful commands:
+
+=over 3
+
+=item run [args]
+
+Run the program with the given arguments.
+
+=item break function_name
+
+=item break source.c:xxx
+
+Tells the debugger that we'll want to pause execution when we reach
+either the named function (but see L<perlguts/Internal Functions>!) or the given
+line in the named source file.
+
+=item step
+
+Steps through the program a line at a time.
+
+=item next
+
+Steps through the program a line at a time, without descending into
+functions.
+
+=item continue
+
+Run until the next breakpoint.
+
+=item finish
+
+Run until the end of the current function, then stop again.
+
+=item 'enter'
+
+Just pressing Enter will do the most recent operation again - it's a
+blessing when stepping through miles of source code.
+
+=item print
+
+Execute the given C code and print its results. B<WARNING>: Perl makes
+heavy use of macros, and F<gdb> is not aware of macros. You'll have to
+substitute them yourself. So, for instance, you can't say
+
+    print SvPV_nolen(sv)
+
+but you have to say
+
+    print Perl_sv_2pv_nolen(sv)
+
+You may find it helpful to have a "macro dictionary", which you can
+produce by saying C<cpp -dM perl.c | sort>. Even then, F<cpp> won't
+recursively apply the macros for you. 
+
+=back
+
+=head2 Dumping Perl Data Structures
+
+One way to get around this macro hell is to use the dumping functions in
+F<dump.c>; these work a little like an internal
+L<Devel::Peek|Devel::Peek>, but they also cover OPs and other structures
+that you can't get at from Perl. Let's take an example. We'll use the
+C<$a = $b + $c> we used before, but give it a bit of context: 
+C<$b = "6XXXX"; $c = 2.3;>. Where's a good place to stop and poke around?
+
+What about C<pp_add>, the function we examined earlier to implement the
+C<+> operator:
+
+    (gdb) break Perl_pp_add
+    Breakpoint 1 at 0x46249f: file pp_hot.c, line 309.
+
+Notice we use C<Perl_pp_add> and not C<pp_add> - see L<perlguts/Internal Functions>.
+With the breakpoint in place, we can run our program:
+
+    (gdb) run -e '$b = "6XXXX"; $c = 2.3; $a = $b + $c'
+
+Lots of junk will go past as gdb reads in the relevant source files and
+libraries, and then:
+
+    Breakpoint 1, Perl_pp_add () at pp_hot.c:309
+    309         dSP; dATARGET; tryAMAGICbin(add,opASSIGN);
+    (gdb) step
+    311           dPOPTOPnnrl_ul;
+    (gdb)
+
+We looked at this bit of code before, and we said that C<dPOPTOPnnrl_ul>
+arranges for two C<NV>s to be placed into C<left> and C<right> - let's
+slightly expand it:
+
+    #define dPOPTOPnnrl_ul  NV right = POPn; \
+                            SV *leftsv = TOPs; \
+                            NV left = USE_LEFT(leftsv) ? SvNV(leftsv) : 0.0
+
+C<POPn> takes the SV from the top of the stack and obtains its NV either
+directly (if C<SvNOK> is set) or by calling the C<sv_2nv> function.
+C<TOPs> takes the next SV from the top of the stack - yes, C<POPn> uses
+C<TOPs> - but doesn't remove it. We then use C<SvNV> to get the NV from
+C<leftsv> in the same way as before - yes, C<POPn> uses C<SvNV>. 
+
+Since we don't have an NV for C<$b>, we'll have to use C<sv_2nv> to
+convert it. If we step again, we'll find ourselves there:
+
+    Perl_sv_2nv (sv=0xa0675d0) at sv.c:1669
+    1669        if (!sv)
+    (gdb)
+
+We can now use C<Perl_sv_dump> to investigate the SV:
+
+    SV = PV(0xa057cc0) at 0xa0675d0
+    REFCNT = 1
+    FLAGS = (POK,pPOK)
+    PV = 0xa06a510 "6XXXX"\0
+    CUR = 5
+    LEN = 6
+    $1 = void
+
+We know we're going to get C<6> from this, so let's finish the
+subroutine:
+
+    (gdb) finish
+    Run till exit from #0  Perl_sv_2nv (sv=0xa0675d0) at sv.c:1671
+    0x462669 in Perl_pp_add () at pp_hot.c:311
+    311           dPOPTOPnnrl_ul;
+
+We can also dump out this op: the current op is always stored in
+C<PL_op>, and we can dump it with C<Perl_op_dump>. This'll give us
+similar output to L<B::Debug|B::Debug>.
+
+    {
+    13  TYPE = add  ===> 14

+
+=head2 Patching
+
+All right, we've now had a look at how to navigate the Perl sources and
+some things you'll need to know when fiddling with them. Let's now get
+on and create a simple patch. Here's something Larry suggested: if a
+C<U> is the first active format during a C<pack>, (for example, 
+C<pack "U3C8", @stuff>) then the resulting string should be treated as
+UTF8 encoded.
+
+How do we prepare to fix this up? First we locate the code in question -
+the C<pack> happens at runtime, so it's going to be in one of the F<pp>
+files. Sure enough, C<pp_pack> is in F<pp.c>. Since we're going to be
+altering this file, let's copy it to F<pp.c~>.
+
+Now let's look over C<pp_pack>: we take a pattern into C<pat>, and then
+loop over the pattern, taking each format character in turn into
+C<datum_type>. Then for each possible format character, we swallow up
+the other arguments in the pattern (a field width, an asterisk, and so
+on) and convert the next chunk input into the specified format, adding
+it onto the output SV C<cat>.
+
+How do we know if the C<U> is the first format in the C<pat>? Well, if
+we have a pointer to the start of C<pat> then, if we see a C<U> we can
+test whether we're still at the start of the string. So, here's where
+C<pat> is set up:
+
+    STRLEN fromlen;
+    register char *pat = SvPVx(*++MARK, fromlen);
+    register char *patend = pat + fromlen;
+    register I32 len;
+    I32 datumtype;
+    SV *fromstr;
+
+We'll have another string pointer in there:
+
+    STRLEN fromlen;
+    register char *pat = SvPVx(*++MARK, fromlen);
+    register char *patend = pat + fromlen;
+ +  char *patcopy;
+    register I32 len;
+    I32 datumtype;
+    SV *fromstr;
+
+And just before we start the loop, we'll set C<patcopy> to be the start
+of C<pat>:
+
+    items = SP - MARK;
+    MARK++;
+    sv_setpvn(cat, "", 0);
+ +  patcopy = pat;
+    while (pat < patend) {
+
+Now if we see a C<U> which was at the start of the string, we turn on
+the UTF8 flag for the output SV, C<cat>:
+
+ +  if (datumtype == 'U' && pat==patcopy+1)
+ +      SvUTF8_on(cat);
+    if (datumtype == '#') {
+        while (pat < patend && *pat != '\n')
+            pat++;
+
+Remember that it has to be C<patcopy+1> because the first character of
+the string is the C<U> which has been swallowed into C<datumtype!>
+
+Oops, we forgot one thing: what if there are spaces at the start of the
+pattern? C<pack("  U*", @stuff)> will have C<U> as the first active
+character, even though it's not the first thing in the pattern. In this
+case, we have to advance C<patcopy> along with C<pat> when we see spaces:
+
+    if (isSPACE(datumtype))
+        continue;
+
+needs to become
+
+    if (isSPACE(datumtype)) {
+        patcopy++;
+        continue;
+    }
+
+OK. That's the C part done. Now we must do two additional things before
+this patch is ready to go: we've changed the behaviour of Perl, and so
+we must document that change. We must also provide some more regression
+tests to make sure our patch works and doesn't create a bug somewhere
+else along the line.
+
+The regression tests for each operator live in F<t/op/>, and so we make
+a copy of F<t/op/pack.t> to F<t/op/pack.t~>. Now we can add our tests
+to the end. First, we'll test that the C<U> does indeed create Unicode
+strings:
+
+ print 'not ' unless "1.20.300.4000" eq sprintf "%vd", pack("U*",1,20,300,4000);
+ print "ok $test\n"; $test++;
+
+Now we'll test that we got that space-at-the-beginning business right:
+
+ print 'not ' unless "1.20.300.4000" eq
+                     sprintf "%vd", pack("  U*",1,20,300,4000);
+ print "ok $test\n"; $test++;
+
+And finally we'll test that we don't make Unicode strings if C<U> is B<not>
+the first active format:
+
+ print 'not ' unless v1.20.300.4000 ne
+                     sprintf "%vd", pack("C0U*",1,20,300,4000);
+ print "ok $test\n"; $test++;
+
+Mustn't forget to change the number of tests which appears at the top, or
+else the automated tester will get confused:
+
+ -print "1..156\n";
+ +print "1..159\n";
+
+We now compile up Perl, and run it through the test suite. Our new
+tests pass, hooray!
+
+Finally, the documentation. The job is never done until the paperwork is
+over, so let's describe the change we've just made. The relevant place
+is F<pod/perlfunc.pod>; again, we make a copy, and then we'll insert
+this text in the description of C<pack>:
+
+ =item *
+
+ If the pattern begins with a C<U>, the resulting string will be treated
+ as Unicode-encoded. You can force UTF8 encoding on in a string with an
+ initial C<U0>, and the bytes that follow will be interpreted as Unicode
+ characters. If you don't want this to happen, you can begin your pattern
+ with C<C0> (or anything else) to force Perl not to UTF8 encode your
+ string, and then follow this with a C<U*> somewhere in your pattern.
+
+All done. Now let's create the patch. F<Porting/patching.pod> tells us
+that if we're making major changes, we should copy the entire directory
+to somewhere safe before we begin fiddling, and then do
+
+    diff -ruN old new > patch
+
+However, we know which files we've changed, and we can simply do this:
+
+    diff -u pp.c~             pp.c             >  patch
+    diff -u t/op/pack.t~      t/op/pack.t      >> patch
+    diff -u pod/perlfunc.pod~ pod/perlfunc.pod >> patch
+
+We end up with a patch looking a little like this:

+    --- pp.c~       Fri Jun 02 04:34:10 2000

+=head1 EXTERNAL TOOLS FOR DEBUGGING PERL
+
+Sometimes it helps to use external tools while debugging and
+testing Perl.  This section tries to guide you through using
+some common testing and debugging tools with Perl.  This is
+meant as a guide to interfacing these tools with Perl, not
+as any kind of guide to the use of the tools themselves.
+
+=head2 Rational Software's Purify
+
+Purify is a commercial tool that is helpful in identifying
+memory overruns, wild pointers, memory leaks and other such
+badness.  Perl must be compiled in a specific way for
+optimal testing with Purify.  Purify is available under
+Windows NT, Solaris, HP-UX, SGI, and Siemens Unix.
+
+The only currently known leaks happen when there are
+compile-time errors within eval or require.  (Fixing these
+is non-trivial, unfortunately, but they must be fixed
+eventually.)
+
+=head2 Purify on Unix
+
+On Unix, Purify creates a new Perl binary.  To get the most
+benefit out of Purify, you should create the perl to Purify
+using:
+
+    sh Configure -Accflags=-DPURIFY -Doptimize='-g' \
+     -Uusemymalloc -Dusemultiplicity
+
+where these arguments mean:
+
+=over 4
+
+=item -Accflags=-DPURIFY
+
+Disables Perl's arena memory allocation functions, as well as
+forcing use of memory allocation functions derived from the
+system malloc.
+
+=item -Doptimize='-g'
+
+Adds debugging information so that you see the exact source
+statements where the problem occurs.  Without this flag, all
+you will see is the source filename of where the error occurred.
+

+Once you've compiled a perl suitable for Purify'ing, then you
+can just:
+
+    make pureperl   
+
+which creates a binary named 'pureperl' that has been Purify'ed.
+This binary is used in place of the standard 'perl' binary
+when you want to debug Perl memory problems.
+
+As an example, to show any memory leaks produced during the
+standard Perl testset you would create and run the Purify'ed
+perl as:
+
+    make pureperl
+    cd t
+    ../pureperl -I../lib harness 
+
+which would run Perl on test.pl and report any memory problems.
+
+Purify outputs messages in "Viewer" windows by default.  If
+you don't have a windowing environment or if you simply
+want the Purify output to unobtrusively go to a log file
+instead of to the interactive window, use these following
+options to output to the log file "perl.log":
+
+    setenv PURIFYOPTIONS "-chain-length=25 -windows=no \
+     -log-file=perl.log -append-logfile=yes"

+=head2 CONCLUSION
+
+We've had a brief look around the Perl source, an overview of the stages
+F<perl> goes through when it's running your code, and how to use a
+debugger to poke at the Perl guts. We took a very simple problem and
+demonstrated how to solve it fully - with documentation, regression
+tests, and finally a patch for submission to p5p.  Finally, we talked
+about how to use external tools to debug and test Perl.
+
+I'd now suggest you read over those references again, and then, as soon
+as possible, get your hands dirty. The best way to learn is by doing,
+so: 
+
+=over 3
+
+=item *
+
+Subscribe to perl5-porters, follow the patches and try and understand
+them; don't be afraid to ask if there's a portion you're not clear on -
+who knows, you may unearth a bug in the patch...
+
+=item *
+
+Keep up to date with the bleeding edge Perl distributions and get
+familiar with the changes. Try and get an idea of what areas people are
+working on and the changes they're making.
+
+=item *
+
+Do read the README associated with your operating system, e.g. README.aix
+on the IBM AIX OS. Don't hesitate to supply patches to that README if
+you find anything missing or changed over a new OS release.
+
+=item *
+
+Find an area of Perl that seems interesting to you, and see if you can
+work out how it works. Scan through the source, and step over it in the
+debugger. Play, poke, investigate, fiddle! You'll probably get to
+understand not just your chosen area but a much wider range of F<perl>'s
+activity as well, and probably sooner than you'd think.

+Check the contents of the distribution.
+Read the module's documentation, looking for

+must be compiled, and you cannot install it "out of the box."
+(See L<"PORTABILITY">.)
+
+If a module does not work on MacPerl but should, or needs to be
+compiled, see if the module exists already as a port on the
+MacPerl Module Porters site (http://pudge.net/mmp/).
+For more information on doing XS with MacPerl yourself, see
+Arved Sandstrom's XS tutorial (http://macperl.com/depts/Tutorials/),
+and then consider uploading your binary to the CPAN and
+registering it on the MMP site.
 
-Overview: You need MPW and a combination of new and old CodeWarrior
-compilers for MPW and libraries.  Makefiles created for building under
-MPW use Metrowerks compilers.  It's most likely possible to build
-without other compilers, but it has not been done successfully, to our
-knowledge.  Read the documentation in I<MacPerl: Power and Ease> (
-http://www.ptf.com/macperl/ ) on porting/building extensions, or find
-an existing precompiled binary, or hire someone to build it for you.
+D. INSTALL
 
-Or, ask someone on the mac-perl mailing list (mac-perl@iis.ee.ethz.ch)

-there.  For example:
+there.

+=item FETCHSIZE this
+
+Returns the total number of items in the tied array associated with

+
+    sub FETCHSIZE {
+      my $self = shift;

+If the array becomes smaller then entries beyond count should be

+
+Verify that the element at index I<key> exists in the tied array I<this>.

-arrays of arrays, hashes of arrays, arrays of hashes, hashes of hashes,
-more elaborate constructs
+Does concept match the general goals of Perl?, Where is the
+implementation?, Backwards compatibility, Could it be a module instead?, Is
+the feature generic enough?, Does it potentially introduce new bugs?, Does
+it preclude other desirable features?, Is the implementation robust?, Is
+the implementation generic enough to be portable?, Is there enough
+documentation?, Is there another way to do it?, Does it create too much

+As VM/ESA doesn't fully support the fork() API programs relying on this

+When using perl on VM/ESA please keep in mind that the EBCDIC and ASCII

+does not inspect the memory pointed by this parameter, but will write
+through this pointer to provide additional return values.
+
+Parameters preceded by C<OUTLIST> keyword do not appear in the usage
+signature of the generated Perl function.
+
+Parameters preceded by C<IN_OUTLIST>/C<IN_OUT>/C<OUT> I<do> appear as
+parameters to the Perl function.  With the exception of
+C<OUT>-parameters, these parameters are converted to the corresponding
+C type, then pointers to these data are given as arguments to the C
+function.  It is expected that the C function will write through these
+pointers.
+
+The return list of the generated Perl function consists of the C return value
+from the function (unless the XSUB is of C<void> return type or
+C<The NO_OUTPUT Keyword> was used) followed by all the C<OUTLIST>
+and C<IN_OUTLIST> parameters (in the order of appearance).  On the
+return from the XSUB the C<IN_OUT>/C<OUT> Perl parameter will be
+modified to have the values written by the C function.
+
+For example, an XSUB
+
+  void
+  day_month(OUTLIST day, IN unix_time, OUTLIST month)
+    int day
+    int unix_time
+    int month
+
+should be used from Perl as
+
+  my ($day, $month) = day_month(time);
+
+The C signature of the corresponding function should be
+
+  void day_month(int *day, int unix_time, int *month);
+
+The C<IN>/C<OUTLIST>/C<IN_OUTLIST>/C<IN_OUT>/C<OUT> keywords can be
+mixed with ANSI-style declarations, as in
+
+  void
+  day_month(OUTLIST int day, int unix_time, OUTLIST int month)
+
+(here the optional C<IN> keyword is omitted).
+
+The C<IN_OUT> parameters are identical with parameters introduced with
+L<The & Unary Operator> and put into the C<OUTPUT:> section (see
+L<The OUTPUT: Keyword>).  The C<IN_OUTLIST> parameters are very similar,
+the only difference being that the value C function writes through the
+pointer would not modify the Perl parameter, but is put in the output
+list.
+
+The C<OUTLIST>/C<OUT> parameter differ from C<IN_OUTLIST>/C<IN_OUT>
+parameters only by the the initial value of the Perl parameter not
+being read (and not being given to the C function - which gets some
+garbage instead).  For example, the same C function as above can be

+
+  void day_month(OUT int day, int unix_time, OUT int month);

+  day_month(day, unix_time, month)

+
+=head2 New Things in this Example
+
+There are a number of new concepts introduced here, described below:
+
+=over 4
+
+=item *
+
+This function does not use a typemap.  Instead, we declare it as accepting
+one SV* (scalar) parameter, and returning an SV* value, and we take care of
+populating these scalars within the code.  Because we are only returning
+one value, we don't need a C<PPCODE:> directive - instead, we use C<CODE:>
+and C<OUTPUT:> directives.
+
+=item *
+
+When dealing with references, it is important to handle them with caution.
+The C<INIT:> block first checks that
+C<SvROK> returns true, which indicates that paths is a valid reference.  It
+then verifies that the object referenced by paths is an array, using C<SvRV>
+to dereference paths, and C<SvTYPE> to discover its type.  As an added test,
+it checks that the array referenced by paths is non-empty, using the C<av_len>
+function (which returns -1 if the array is empty).  The XSRETURN_UNDEF macro
+is used to abort the XSUB and return the undefined value whenever all three of
+these conditions are not met.
+
+=item *
+
+We manipulate several arrays in this XSUB.  Note that an array is represented
+internally by an AV* pointer.  The functions and macros for manipulating
+arrays are similar to the functions in Perl: C<av_len> returns the highest
+index in an AV*, much like $#array; C<av_fetch> fetches a single scalar value
+from an array, given its index; C<av_push> pushes a scalar value onto the
+end of the array, automatically extending the array as necessary.
+
+Specifically, we read pathnames one at a time from the input array, and
+store the results in an output array (results) in the same order.  If
+statfs fails, the element pushed onto the return array is the value of
+errno after the failure.  If statfs succeeds, though, the value pushed
+onto the return array is a reference to a hash containing some of the
+information in the statfs structure.
+
+As with the return stack, it would be possible (and a small performance win)
+to pre-extend the return array before pushing data into it, since we know
+how many elements we will return:
+
+	av_extend(results, numpaths);
+
+=item *
+
+We are performing only one hash operation in this function, which is storing
+a new scalar under a key using C<hv_store>.  A hash is represented by an HV*
+pointer.  Like arrays, the functions for manipulating hashes from an XSUB
+mirror the functionality available from Perl.  See L<perlguts> and L<perlapi>
+for details.
+
+=item *
+
+To create a reference, we use the C<newRV> function.  Note that you can
+cast an AV* or an HV* to type SV* in this case (and many others).  This
+allows you to take references to arrays, hashes and scalars with the same
+function.  Conversely, the C<SvRV> function always returns an SV*, which may
+need to be be cast to the appropriate type if it is something other than a
+scalar (check with C<SvTYPE>).
+
+=item *
+
+At this point, xsubpp is doing very little work - the differences between
+Mytest.xs and Mytest.c are minimal.

-#
-# What pod2latex does:
-# 1. Pod file 'perl_doc_entry.pod' is filtered to 'perl_doc_entry.tex'.
-# 2. Indented paragraphs are translated into
-#    '\begin{verbatim} ... \end{verbatim}'.
-# 3. '=head1 heading' command is translated into '\section{heading}'
-# 4. '=head2 heading' command is translated into '\subsection*{heading}'
-# 5. '=over N' command is translated into
-#        '\begin{itemize}'	if following =item starts with *,
-#        '\begin{enumerate}'	if following =item starts with 1.,
-#        '\begin{description}'	if else.
-#      (indentation level N is ignored.)
-# 6. '=item * heading' command is translated into '\item heading',
-#    '=item 1. heading' command is translated into '\item heading',
-#    '=item heading' command(other) is translated into '\item[heading]'.
-# 7. '=back' command is translated into
-#        '\end{itemize}'	if started with '\begin{itemize}',
-#        '\end{enumerate}'	if started with '\begin{enumerate}',
-#        '\end{description}'	if started with '\begin{description}'.
-# 8. other paragraphs are translated into strings with TeX special characters
-#    escaped.
-# 9. In heading text, and other paragraphs, the following translation of pod
-#    quotes are done, and then TeX special characters are escaped after that.
-#      I<text> to {\em text\/},
-#      B<text> to {\bf text},
-#      S<text> to text1,
-#        where text1 is a string with blank characters replaced with ~,
-#      C<text> to {\tt text2},
-#        where text2 is a string with TeX special characters escaped to
-#        obtain a literal printout,
-#      E<text> (HTML escape) to TeX escaped string,
-#      L<text> to referencing string as is done by pod2man,
-#      F<file> to {\em file\/},
-#      Z<> to a null string,
-# 10. those headings are indexed:
-#       '=head1 heading'   =>  \section{heading}\index{heading}
-#       '=head2 heading'   =>  \subsection*{heading}\index{heading}
-#                 only when heading does not match frequent patterns such as
-#                 DESCRIPTION, DIAGNOSTICS,...
-#       '=item heading'   =>  \item{heading}\index{heading}
-#
-# Usage:
-#     pod2latex perl_doc_entry.pod
-# this will write to a file 'perl_doc_entry.tex'.
-#
-# To LaTeX:
-# The following commands need to be defined in the preamble of the LaTeX
-# document:
-# \def\C++{{\rm C\kern-.05em\raise.3ex\hbox{\footnotesize ++}}}
-# \def\underscore{\leavevmode\kern.04em\vbox{\hrule width 0.4em height 0.3pt}}
-# and \parindent should be set zero:
-# \setlength{\parindent}{0pt}
-#
-# Note:
-# This script was written modifing pod2man.
-#
-# Bug:
-# If HTML escapes E<text> other than E<amp>,E<lt>,E<gt>,E<quot> are used
-# in C<>, translation will produce wrong character strings.
-# Translation of HTML escapes of various European accents might be wrong.
-

-    return $retstr;
-}
+C<pod2latex> is a program to convert POD format documentation
+(L<perlpod>) into latex. It can process multiple input documents at a
+time and either generate a latex file per input document or a single
+combined output file.
+
+=head1 OPTIONS AND ARGUMENTS
+
+This section describes the supported command line options. Minium
+matching is supported.
+
+=over 4
+
+=item B<-out>
+
+Name of the output file to be used. If there are multiple input pods
+it is assumed that the intention is to write all translated output
+into a single file. C<.tex> is appended if not present.  If the
+argument is not supplied, a single document will be created for each
+input file.
+
+=item B<-full>
+
+Creates a complete C<latex> file that can be processed immediately
+(unless C<=for/=begin> directives are used that rely on extra packages).
+Table of contents and index generation commands are included in the
+wrapper C<latex> code.
+
+=item B<-sections>
+
+Specify pod sections to include (or remove if negated) in the
+translation.  See L<Pod::Select/"SECTION SPECIFICATIONS"> for the
+format to use for I<section-spec>. This option may be given multiple
+times on the command line.This is identical to the similar option in
+the C<podselect()> command.
+
+=item B<-modify>
+
+This option causes the output C<latex> to be slightly
+modified from the input pod such that when a C<=head1 NAME>
+is encountered a section is created containing the actual
+pod name (rather than B<NAME>) and all subsequent C<=head1>
+directives are treated as subsections. This has the advantage
+that the description of a module will be in its own section
+which is helpful for including module descriptions in documentation.
+Also forces C<latex> label and index entries to be prefixed by the
+name of the module.
+
+=item B<-help>
+
+Print a brief help message and exit.
+
+=item B<-man>
+
+Print the manual page and exit.
+
+=item B<-verbose>
+
+Print information messages as each document is processed.
+
+=back
+
+=head1 BUGS
+
+Known bugs are:
+
+=over 4
+
+=item * 
+
+Cross references between documents are not resolved when multiple
+pod documents are converted into a single output C<latex> file.
+
+=item * 
+
+Functions and variables are not automatically recognized 
+and they will therefore not be marked up in any special way
+unless instructed by an explicit pod command.

+=head2 Extension based on F<.h> and F<.c> files
+
+Suppose that you have some C files implementing some functionality,
+and the corresponding header files.  How to create an extension which
+makes this functionality accessable in Perl?  The example below
+assumes that the header files are F<interface_simple.h> and
+I<interface_hairy.h>, and you want the perl module be named as
+C<Ext::Ension>.  If you need some preprocessor directives and/or
+linking with external libraries, see the flags C<-F>, C<-L> and C<-l>
+in L<"OPTIONS">.
+
+=over
+
+=item Find the directory name
+
+Start with a dummy run of h2xs:
+
+  h2xs -Afn Ext::Ension
+
+The only purpose of this step is to create the needed directories, and
+let you know the names of these directories.  From the output you can
+see that the directory for the extension is F<Ext/Ension>.
+
+=item Copy C files
+
+Copy your header files and C files to this directory F<Ext/Ension>.
+
+=item Create the extension
+
+Run h2xs, overwriting older autogenerated files:
+
+  h2xs -Oxan Ext::Ension interface_simple.h interface_hairy.h
+
+h2xs looks for header files I<after> changing to the extension
+directory, so it will find your header files OK.
+
+=item Archive and test
+
+As usual, run
+
+  cd Ext/Ension
+  perl Makefile.PL
+  make dist
+  make
+  make test
+
+=item Hints
+
+It is important to do C<make dist> as early as possible.  This way you
+can easily merge(1) your changes to autogenerated files if you decide
+to edit your C<.h> files and rerun h2xs.
+
+Do not forget to edit the documentation in the generated F<.pm> file.
+
+Consider the autogenerated files as skeletons only, you may invent
+better interfaces than what h2xs could guess.
+
+Consider this section as a guideline only, some other options of h2xs
+may better suit your needs.

 =head1 DESCRIPTION
 
-'perlcc' is the frontend into the perl compiler. Typing 'perlcc a.p'
-compiles the code inside a.p into a standalone executable, and 
-perlcc A.pm will compile into a shared object, A.so, suitable for inclusion 
-into a perl program via "use A".
+F<perlcc> creates standalone executables from Perl programs, using the
+code generators provided by the L<B> module. At present, you may
+either create executable Perl bytecode, using the C<-B> option, or 
+generate and compile C files using the standard and 'optimised' C
+backends.
 
-There are quite a few flags to perlcc which help with such issues as compiling 
-programs in bulk, testing compiled programs for compatibility with the 
-interpreter, and controlling.
+The code generated in this way is not guaranteed to work. The whole
+codegen suite (C<perlcc> included) should be considered B<very>
+experimental. Use for production purposes is strongly discouraged.
 
-=head1 OPTIONS 
+=head1 OPTIONS
 
 =over 4
 
-=item -L < library_directories >
-
-Adds directories in B<library_directories> to the compilation command.
-
-=item -I  < include_directories > 
-
-Adds directories inside B<include_directories> to the compilation command.
-
-=item -C   < c_code_name > 
-
-Explicitly gives the name B<c_code_name> to the generated file containing
-the C code which is to be compiled. Can only be used if compiling one file
-on the command line.
-
-=item -o   < executable_name >
-
-Explicitly gives the name B<executable_name> to the executable which is to be
-compiled. Can only be used if compiling one file on the command line.
-
-=item -e   < perl_line_to_execute>
-
-Compiles 'one liners', in the same way that B<perl -e> runs text strings at 
-the command line. Default is to have the 'one liner' be compiled, and run all
-in one go (see B<-run>); giving the B<-o> flag saves the resultant executable, 
-rather than throwing it away. Use '-argv' to pass arguments to the executable
-created.
-
-=item -b
+=item -LI<library directories>
 
-Generates bytecode instead of C code.
+Adds the given directories to the library search path when C code is
+passed to your C compiler.
 
-=item -opt
+=item -II<include directories>
 
-Uses the optimized C backend (C<B::CC>)rather than the simple C backend
-(C<B::C>).  Beware that the optimized C backend creates very large
-switch structures and structure initializations.  Many C compilers
-find it a challenge to compile the resulting output in finite amounts
-of time.  Many Perl features such as C<goto LABEL> are also not
-supported by the optimized C backend.  The simple C backend should
-work in more instances, but can only offer modest speed increases.
+Adds the given directories to the include file search path when C code is
+passed to your C compiler; when using the Perl bytecode option, adds the
+given directories to Perl's include path.
 
-=item -regex   <rename_regex>
+=item -o I<output file name>
 
-Gives a rule B<rename_regex> - which is a legal perl regular expression - to 
-create executable file names.
+Specifies the file name for the final compiled executable.
 
-=item -verbose <verbose_level>
+=item -c I<C file name>
 
-Show exactly what steps perlcc is taking to compile your code. You can
-change the verbosity level B<verbose_level> much in the same way that
-the C<-D> switch changes perl's debugging level, by giving either a
-number which is the sum of bits you want or a list of letters
-representing what you wish to see. Here are the verbosity levels so
-far :
+Create C code only; do not compile to a standalone binary.
 
-    Bit 1(g):      Code Generation Errors to STDERR
-    Bit 2(a):      Compilation Errors to STDERR
-    Bit 4(t):      Descriptive text to STDERR 
-    Bit 8(f):      Code Generation Errors to file (B<-log> flag needed)
-    Bit 16(c):     Compilation Errors to file (B<-log> flag needed)
-    Bit 32(d):     Descriptive text to file (B<-log> flag needed) 
+=item -e I<perl code>
 
-If the B<-log> tag is given, the default verbose level is 63 (ie: mirroring 
-all of perlcc's output to both the screen and to a log file). If no B<-log>
-tag is given, then the default verbose level is 7 (ie: outputting all of 
-perlcc's output to STDERR).
+Compile a one-liner, much the same as C<perl -e '...'>
 
-NOTE: Because of buffering concerns, you CANNOT shadow the output of '-run' to
-both a file, and to the screen! Suggestions are welcome on how to overcome this
-difficulty, but for now it simply does not work properly, and hence will only go
-to the screen.
+=item -S
 
-=item -log <logname>
+Do not delete generated C code after compilation.
 
-Opens, for append, a logfile to save some or all of the text for a given 
-compile command. No rewrite version is available, so this needs to be done 
-manually.

+Use the 'optimised' C code generator. This is more experimental than

-Tells perl to save the intermediate C code. Usually, this C code is the name

-for example. If used with the C<-e> operator, you need to tell perlcc where to 
-save resulting executables.

+Increase verbosity of output; can be repeated for more verbose output.
 
-Tells perlcc to only create the intermediate C code, and not compile the

+Run the resulting compiled script after compiling it.
 
-Immediately run the perl code that has been generated. NOTE: IF YOU GIVE THE 
-B<-run> FLAG TO B<perlcc>, THEN THE REST OF @ARGV WILL BE INTERPRETED AS 
-ARGUMENTS TO THE PROGRAM THAT YOU ARE COMPILING.
+=item -log
 
-=item -prog
-
-Indicate that the programs at the command line are programs, and should be
-compiled as such. B<perlcc> will automatically determine files to be

-
-Indicate that the programs at the command line are modules, and should be

 =back
 
-=head1 ENVIRONMENT
-
-Most of the work of B<perlcc> is done at the command line. However, you can 
-change the heuristic which determines what is a module and what is a program.
-As indicated above, B<perlcc> assumes that the extensions:
-
-.p$, .pl$, and .bat$
-
-indicate a perl program, and:
-
-.pm$
-
-indicate a library, for the purposes of creating executables. And furthermore,
-by default, these extensions will be replaced (and dropped) in the process of 
-creating an executable. 
-
-To change the extensions which are programs, and which are modules, set the
-environmental variables:
-
-PERL_SCRIPT_EXT
-PERL_MODULE_EXT
-
-These two environmental variables take colon-separated, legal perl regular 
-expressions, and are used by perlcc to decide which objects are which. 
-For example:
-
-setenv PERL_SCRIPT_EXT  '.prl$:.perl$'
-prompt%   perlcc sample.perl
-
-will compile the script 'sample.perl' into the executable 'sample', and
-
-setenv PERL_MODULE_EXT  '.perlmod$:.perlmodule$'
-
-prompt%   perlcc sample.perlmod
-
-will  compile the module 'sample.perlmod' into the shared object 
-'sample.so'
-
-NOTE: the '.' in the regular expressions for PERL_SCRIPT_EXT and PERL_MODULE_EXT
-is a literal '.', and not a wild-card. To get a true wild-card, you need to 
-backslash the '.'; as in:
-
-setenv PERL_SCRIPT_EXT '\.\.\.\.\.'
-
-which would have the effect of compiling ANYTHING (except what is in 
-PERL_MODULE_EXT) into an executable with 5 less characters in its name.
-
-The PERLCC_OPTS environment variable can be set to the default flags
-that must be used by the compiler.
-
-The PERLCC_TIMEOUT environment variable can be set to the number of
-seconds to wait for the backends before giving up.  This is sometimes
-necessary to avoid some compilers taking forever to compile the
-generated output.  May not work on Windows and similar platforms.
-
-=head1 FILES
-
-'perlcc' uses a temporary file when you use the B<-e> option to evaluate 
-text and compile it. This temporary file is 'perlc$$.p'. The temporary C code is
-perlc$$.p.c, and the temporary executable is perlc$$.
-
-When you use '-run' and don't save your executable, the temporary executable is
-perlc$$
-
-=head1 BUGS
-
-The whole compiler suite (C<perlcc> included) should be considered very
-experimental.  Use for production purposes is strongly discouraged.
-
-perlcc currently cannot compile shared objects on Win32. This should be fixed
-in future.
-
-Bugs in the various compiler backends still exist, and are perhaps too
-numerous to list here.
