+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 675 Mass Ave, Cambridge, MA 02139, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ Appendix: How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) 19yy <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) 19yy name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+
+ dialog - Display dialog boxes in shell script (version 0.3)
+ ===========================================================
+
+This is a program that will enable you to present a variety of questions or
+display messages using dialog boxes from a shell script. Currently, these
+types of dialog boxes are implemented: yes/no box, menu box, input box,
+message box, text box, info box, checklist box. The idea of writing this
+program came from the fact that most questions asked in a shell script (and
+many interactive programs as well) can be classified into these few types:
+
+
+ 1) One that requires the user to answer either yes or no.
+
+ 2) One that presents a number of options for the user to choose.
+
+ 3) One that requires the user to input a string.
+
+ 4) One that displays a message and optionally wait for a key press
+ before continuing.
+
+ 5) One that presents a list of options that can be turned on or off.
+
+
+The program 'dialog' can, say for example, be called in a shell script to
+present the first type of questions like this:
+
+
+ if dialog --yesno <question text> <height> <width>
+ then
+ ...
+ fi
+
+
+ e.g. if dialog --yesno "Do you want to continue?" 7 51
+ then
+ echo "Continuing..."
+ else
+ echo "Aborting..."
+ fi
+
+
+I've included a sample shell script for each type of boxes in the directory
+samples. The program requires ncurses to compile. Running 'dialog' without
+arguments will display the usage.
+
+
+
+FEATURES
+--------
+
+ * Friendly dialog box interface with buttons, etc.
+
+ * Auto wrap around of question text if it's too long to fit on
+ one line.
+
+ * "\n" can be inserted in question text to control line breaking
+ explicitly. The real newline character '\n' can also be used.
+
+ * run-time configruation of color settings and other options using
+ a configuration file.
+
+
+
+WHAT'S NEW SINCE VERSION 0.21?
+------------------------------
+
+ * some changes for faster screen update.
+
+ * much more flexible color settings. Can use all 16 colors
+ (8 normal, 8 highlight) of the Linux console.
+
+ * added run-time configuration using configuration file.
+
+ * some minor bug fixes and cleanups for menubox, checklist and
+ textbox.
+
+ * added a man page.
+
+ * some changes for easier porting to other Unix systems (tested
+ on Ultrix, SunOS and HPUX)
+
+
+
+INSTALLATION
+------------
+
+ 1. cd ./src
+
+ 2. Go to step 3 if your system has ncurses (e.g. Linux).
+ Edit Makefile and remove -DHAVE_NCURSES from DEFS. Also
+ remove rc.c from SRCS and rc.o from OBJS. Change LIBS as
+ appropriate (Usually, it should be '-lcurses -ltermcap').
+ Go to step 6.
+
+ 3. Edit Makefile and remove -DBROKEN_WSCRL from DEFS if you
+ are using ncurses 1.8.3 or newer. Menu scrolling should
+ be faster. DON'T REMOVE IT IF YOU ARE NOT USING AT LEAST
+ VERSION 1.8.3 OF NCURSES.
+
+ 4. Edit dialog.h and change USE_SHADOW to FALSE if you don't
+ want shadowed dialog boxes. Also change USE_COLORS to
+ FALSE if you don't want colors. Note that 'dialog' will
+ check if the terminal supports colors, and will use mono
+ settings if it doesn't, so USE_COLORS won't do any harm
+ even if you have a mono display. Also note that USE_SHADOW
+ implies USE_COLORS. These two options can be changed at
+ run-time using the run-time configuration file (see below).
+
+ 5. Edit colors.h to change default color definitions if you
+ don't like the defaults. These are only compiled in defaults,
+ you can change them at run-time using the run-time
+ configuration file.
+
+ 6. 'make depend; make install' will compile and install the
+ binaries in /usr/local/bin (change BINDIR in Makefile if
+ you want to install elsewhere).
+
+ 7. 'make install.man' will install the man page to
+ /usr/local/man (change MANDIR in Makefile if you want to
+ install elsewhere).
+
+ 8. You can then try the sample shell scripts in the samples
+ directory (make sure the environment variable DIALOG is
+ not set, the scripts use it to find the dialog binary, if
+ it's not set, "../src/dialog" will be used).
+
+ 9. Don't forget to mail me (mail address at end of this file)
+ if you find any bugs, have some good color settings to
+ contribute or just want to tell me that you like it, Don't
+ mail me if you don't like it :-)
+
+
+
+RUN-TIME CONFIGURATION
+----------------------
+
+ 1. Create a sample configuration file by typing:
+
+ "dialog --create-rc <file>"
+
+ 2. At start, 'dialog' determines the settings to use as follows:
+
+ a) if environment variable DIALOGRC is set, it's value
+ determines the name of the configuration file.
+
+ b) if the file in (a) can't be found, use the file
+ $HOME/.dialogrc as the configuration file.
+
+ c) if the file in (b) can't be found, use compiled in
+ defaults.
+
+ 3. Edit the sample configuration file and copy it to some place
+ that 'dialog' can find, as stated in step 2 above.
+
+
+
+
+Comments and bug reports welcome.

+Hi, this is a text dialog box. It can be used to display text from a file.
+The file should not contain any 'tab' characters, so you should 'expand'
+the file first if it contains 'tab' characters.
+
+It's like a simple text file viewer, with these keys implemented:
+
+PGDN/SPACE - Move down one page
+PGUP/'b' - Move up one page
+DOWN/'j' - Move down one line
+UP/'k' - Move up one line
+LEFT/'h' - Scroll left
+RIGHT/'l' - Scroll right
+'0' - Move to beginning of line
+HOME/'g' - Move to beginning of file
+END/'G' - Move to end of file
+'/' - Forward search
+'?' - Backward search
+'n' - Repeat last search (forward)
+'N' - Repeat last search (backward)
+
+
+The following is a sample text file:
+
+
+EOF
+
+cat ../COPYING | expand >> /tmp/textbox.tmp.$$

+.TH DIALOG 1 "10 January 1994"
+.SH NAME
+dialog \- display dialog boxes from shell scripts
+.SH SYNOPSIS
+.B dialog --clear
+.br
+.BI "dialog --create-rc " file
+.br
+.B dialog
+[
+.B \-\-title
+.I title
+]
+[
+.B \-\-clear
+]
+.B box-options
+.SH DESCRIPTION
+.B Dialog
+is a program that will let you to present a variety of questions or
+display messages using dialog boxes from a shell script. Currently,
+these types of dialog boxes are implemented:
+.LP
+.BR yes/no " box," " menu" " box," " input" " box,"
+.BR message " box," " text" " box," " info" " box, and"
+.BR checklist " box."
+.SH OPTIONS
+.TP
+.B \-\-clear
+The screen will be cleared to the
+.BR "screen attribute" " on exit."
+.TP
+.BI \-\-create-rc " file"
+.RB "Since " dialog " supports run-time configuration,"
+this can be used to dump a sample configuration file to the file specified
+by
+.IR file "."
+.TP
+.BI \-\-title " title"
+Specifies a
+.I title
+string to be displayed at the top of the dialog box.
+.TP
+.B Box Options
+.TP
+.BI \-\-yesno " text height width"
+.RB A " yes/no" " dialog box of size"
+.I height
+rows by
+.I width
+columns will be displayed. The string specified by
+.I text
+is displayed inside the dialog box. If this string is too long to be fitted
+in one line, it will be automatically divided into multiple lines at
+appropriate places. The
+.I text
+string may also contain the sub-string
+.I
+"\en"
+or newline characters
+.I `\en\'
+to control line breaking explicitly. This dialog box is useful for
+asking questions that require the user to answer either yes or no.
+.RB "The dialog box has a" " Yes" " button and a " No
+button, in which the user can switch between by pressing the
+.IR TAB " key."
+.TP
+.BI \-\-msgbox " text height width"
+.RB A " message" " box is very similar to a" " yes/no" " box."
+The only difference between a
+.B message
+box and a
+.B yes/no
+box is that a
+.B message
+box has only a single
+.B OK
+button. You can use this dialog box to display any message you like.
+After reading the message, the user can press the
+.I ENTER
+key so that
+.B dialog
+will exit and the calling shell script can continue its operation.
+.TP
+.BI \-\-infobox " text height width"
+.RB An " info" " box is basically a" " message" " box."
+However, in this case,
+.B dialog
+will exit immediately after displaying the message to the user. The
+screen is not cleared when
+.B dialog
+exits, so that the message will remain on the screen until the calling
+shell script clears it later. This is useful when you want to inform
+the user that some operations are carrying on that may require some
+time to finish.
+.TP
+.BI \-\-inputbox " text height width"
+.RB "An " input " box is useful when you want to ask questions that"
+require the user to input a string as the answer. When inputing the
+string, the
+.I BACKSPACE
+key can be used to correct typing errors. If the input string is longer than
+can be fitted in the dialog box, the input field will be scrolled. On exit,
+the input string will be printed on
+.IR stderr "."
+.TP
+.BI \-\-textbox " file height width"
+.RB A " text" " box lets you display the contents of a text file in a"
+dialog box. It is like a simple text file viewer. The user can move
+through the file by using the
+.IR UP/DOWN ", " PGUP/PGDN
+.RI and " HOME/END" " keys available on most keyboards."
+If the lines are too long to be displayed in the box, the
+.I LEFT/RIGHT
+keys can be used to scroll the text region horizontally. For more
+convenience, forward and backward searching functions are also provided.
+.IP "\fB\-\-menu \fItext height width menu-height \fR[ \fItag item \fR] \fI..."
+As its name suggests, a
+.B menu
+box is a dialog box that can be used to present a list of choices in
+the form of a menu for the user to choose. Each menu entry consists of a
+.IR tag " string and an " item " string. The"
+.I tag
+gives the entry a name to distinguish it from the other entries in the
+menu. The
+.I item
+is a short description of the option that the entry represents. The
+user can move between the menu entries by pressing the
+.I UP/DOWN
+keys, the first letter of the
+.I tag
+as a hot-key, or the number keys
+.IR 1-9 ". There are"
+.I menu-height
+entries displayed in the menu at one time, but the menu will be
+scrolled if there are more entries than that. When
+.B dialog
+exits, the
+.I tag
+of the chosen menu entry will be printed on
+.IR stderr "."
+.IP "\fB\-\-checklist \fItext height width list-height \fR[ \fItag item status \fR] \fI..."
+.RB "A " checklist " box is similar to a " menu " box in that there are"
+multiple entries presented in the form of a menu. Instead of choosing
+one entry among the entries, each entry can be turned on or off by the
+user. The initial on/off state of each entry is specified by
+.IR status "."
+On exit, a list of the
+.I tag
+strings of those entries that are turned on will be printed on
+.IR stderr "."
+.SH "RUN-TIME CONFIGURATION"
+.TP 4
+1.
+Create a sample configuration file by typing:
+.LP
+.in +1i
+"dialog --create-rc <file>"
+.TP 4
+2.
+At start,
+.B dialog
+determines the settings to use as follows:
+.RS
+.TP 4
+a)
+if environment variable
+.B DIALOGRC
+is set, it's value determines the name of the configuration file.
+.TP 4
+b)
+if the file in (a) can't be found, use the file
+.I $HOME/.dialogrc
+as the configuration file.
+.TP 4
+c)
+if the file in (b) can't be found, use compiled in defaults.
+.RE
+.TP 4
+3.
+Edit the sample configuration file and copy it to some place that
+.B dialog
+can find, as stated in step 2 above.
+.SH ENVIROMENT
+.TP 15
+.B DIALOGRC
+Define this variable if you want to specify the name of the configuration file
+to use.
+.SH FILES
+.TP 20
+.I $HOME/.dialogrc
+default configuration file
+.SH DIAGNOSTICS
+Exit status is 0 if
+.BR dialog " is exited by pressing the " Yes " or " OK
+button, and 1 if the
+.BR No " or " Cancel
+button is pressed. Otherwise, if errors occur inside
+.B dialog
+or
+.B dialog
+is exited by pressing the
+.I ESC
+key, the exit status is -1.
+.SH BUGS
+Text files containing
+.I tab
+characters may cause problems with
+.B text
+box.
+.I Tab
+characters in text files must first be expanded to spaces before being
+.RB "displayed by " text " box."
+.TP
+Screen update is too slow.

+ *
+ *
+ * HISTORY:
+ *
+ * 17/12/93 - Version 0.1 released.
+ *
+ * 19/12/93 - menu will now scroll if there are more items than can fit
+ * on the screen.
+ * - added 'checklist', a dialog box with a list of options that
+ * can be turned on or off. A list of options that are on is
+ * returned on exit.
+ *
+ * 20/12/93 - Version 0.15 released.
+ *
+ * 29/12/93 - Incorporated patch from Patrick J. Volkerding
+ * (volkerdi@mhd1.moorhead.msus.edu) that made these changes:
+ * - increased MAX_LEN to 2048
+ * - added 'infobox', equivalent to a message box without pausing
+ * - added option '--clear' that will clear the screen
+ * - Explicit line breaking when printing prompt text can be
+ * invoked by real newline '\n' besides the string "\n"
+ * - an optional parameter '--title <string>' can be used to
+ * specify a title string for the dialog box
+ *
+ * 03/01/94 - added 'textbox', a dialog box for displaying text from a file.
+ * - Version 0.2 released.
+ *
+ * 04/01/94 - some fixes and improvements for 'textbox':
+ * - fixed a bug that will cause a segmentation violation when a
+ * line is longer than MAX_LEN characters. Lines will now be
+ * truncated if they are longer than MAX_LEN characters.
+ * - removed wrefresh() from print_line(). This will increase
+ * efficiency of print_page() which calls print_line().
+ * - display current position in the form of percentage into file.
+ * - Version 0.21 released.
+ *
+ * 05/01/94 - some changes for faster screen update.
+ *
+ * 07/01/94 - much more flexible color settings. Can use all 16 colors
+ * (8 normal, 8 highlight) of the Linux console.
+ *
+ * 08/01/94 - added run-time configuration using configuration file.
+ *
+ * 09/01/94 - some minor bug fixes and cleanups for menubox, checklist and
+ * textbox.
+ *
+ * 11/01/94 - added a man page.
+ *
+ * 13/01/94 - some changes for easier porting to other Unix systems (tested
+ * on Ultrix, SunOS and HPUX)
+ * - Version 0.3 released.
+ *
+ * 08/06/94 - Patches by Stuart Herbert - S.Herbert@shef.ac.uk
+ * Fixed attr_clear and the textbox stuff to work with ncurses 1.8.5
+ * Fixed the wordwrap routine - it'll actually wrap properly now
+ * Added a more 3D look to everything - having your own rc file could
+ * prove 'interesting' to say the least :-)
+ * Added radiolist option
+ * - Version 0.4 released.
