>I would like to know if your software BS is under GPL or not.

I did not say anything explicitly about copyright. I guess this means that
I keep the copyright, but I think I should donate bs to the public domain.
So, here it is -- it's public domain.

DESCRIPTION
     bs is a simple button shell for X11.  It is very useful  for repetitive
     tasks  such as edit-compile-run cycles, and also as a general purpose menu.

     See the man page below for more information.

INSTALLATION
     Download bs from ftp://csg.uwaterloo.ca/pub/lhf/bs.tar.gz.
     Then just try xmkmf; make.

     bs needs an ANSI compiler.
     if xmkmf does not use that, you might have to add
	CC = gcc
     or something similar to Imakefile.  Or modify and use Makefile.std.

NAME
     bs - a simple button shell for X11

SYNOPSIS
     bs [ file ] [ Xt options ]

DESCRIPTION
     bs is a simple button shell for X11.  It is useful for
     repetitive tasks such as edit-compile-run cycles, and also
     as a general purpose menu.

     bs builds, displays, and let you interact with a panel com-
     posed of labels and buttons.  Labels contain informative
     text and buttons are associated with commands that are fed
     to a shell, in a pipe.

     bs reads a panel description from the file given in the com-
     mand line, or from the file .bsrc in the current directory
     if no file is given.

     There are 4 kinds of lines in the file describing the panel:
     lines starting with a TAB; lines with a TAB elsewhere; lines
     without a TAB; and empty lines.

     Lines without a TAB represent labels.  The text in the line
     appears verbatim in the panel.

     Lines with a TAB not on the first column represent buttons.
     The text before the TAB is the button text.  The text after
     the TAB is a command fed to the shell when the button is
     pressed.

     Lines starting with a TAB are fed to the shell as soon as bs
     begins.  They typically contain variable definitions, but
     they can contain command.  Because bs sends data to a shell
     using a single pipe that remains open throughout the execu-
     tion, variables definitions remain after this initializa-
     tion.

     Panel layout is controled by empty lines.  Buttons and
     labels appear side by side, from left to right.  An empty
     line signals the start of a new row in the panel.  So,
     descriptions of "horizontal" panels have no empty lines, and
     descriptions of "vertical" panels have an empty line after
     each element, including the last one.

     SPACE characters are significant in labels and button
     labels.  They can be used for alignment, provided a non-
     proportional font is used.

     bs automatically adds a button labeled "quit" in the end of
     the panel; it does the obvious thing.

EXAMPLE
     Here is an example suitable for using TeX:

               F=paper
          paper
          edit xterm -geometry 80x57+0+0 -title $F -e vi $F.tex &
          tex  latex $F.tex </dev/null
          dvi  xdvi -hushspecials -geometry +0+0 $F.dvi &
          ps   dvips -o $F.ps $F.dvi; ghostview $F.ps &
          print     dvips -f $F.dvi | lpr -h

     A similar example would be adequate for compiling C pro-
     grams.

RESOURCES
     bs does not define any new resources.  It uses the following
     widgets from the Athena Widget set: Command, Form, Label.
     All standard X11 toolkit options are accepted on the command
     line.

FILES
     .bsrc

SEE ALSO
     sh(1)

BUGS
     Buttons should stay pressed until the corresponding command
     finishes.  Of course, this only applies to commands that are
     run in the foreground.

     /bin/sh is hard-coded into the program.  Other shells did
     not quite work.
