  'Well.. I was getting things down to just the two .pm files, a file
with all the application code, and then any required pixmaps. I used
this snippet to make the application figure out where things were, no
matter how it was called:

BEGIN
{
        my($exec)= $0;
        if ( -l $exec ) {
                $exec = readlink ($exec);
        }
        @parts = split (/\//,$exec);
        $part = pop (@parts);
        $libpath = join ('/',@parts);
}
use lib $libpath;
chdir $libpath;

  'And this worked pretty well, with only 'like 5 files for my sample
application.

  Then, with help from Chas Owens, I started toying around with the
technique of generating the GUI from .xml, either by a seperate .glade
file or by including it,inline, in the end of a perl script.

  This brought things down to the point that the only external files
were pixmaps!!

  Now Im trying to include the pixmap  in the perl script as well, but
am running into difficulty 'hooking up' a pixmap widget generated from
the xml to the inline pixmap data structure (@xpm_data):

  $window = $app->get_widget("window1");
  $style = $window->get_style()->bg( 'normal' );
  ($pixmap,$mask) =
Gtk::Gdk::Pixmap->create_from_xpm_d($window,$style,@xpm_data);

  'gives me:

Usage: Gtk::Gdk::Pixmap::create_from_xpm_d(Class, window,
transparent_color, data, ...) at ./revldap line 597.
  
  'like the method wants 4 args - not 3..

  My 'goal' in all this was simply to find an equivalent procedure, to
the build process within a C environment to produce a single executable:
You use the linker to combine various .o files, some of which are
generated from C source, some which are from assembly files which simply
have a DATA section to include binary files like images and the like,
and link it all into a single executable - similar to a Java .jar too.

 Im pretty close! I just have to figure out the pixmaps thing.

 Thanks for the help everybody!  :)
