Getopt::Janus -- get program options via command-line or via a GUI

This module is a simple framework for writing programs that can get
their options either on the command line, or via a GUI.

This module requires Tk for running in GUI mode; but without
it, you can still use the command-line mode.

On an MSWindows machine, you can install Tk by just entering this at a
DOS prompt:  ppm install Tk

See perldoc perlmodinstall for the help on installing modules.



Here's a complete sample Janus-using program with just one option:

  use strict;
  use Getopt::Janus;
  choose my $ice_cream, '-i', \"What kind of ice cream",
   'from' => [ 'Lemon sorbet', 'Vanilla ice cream', 'Mango zabaglione' ];
  $ice_cream = 'Mango zabaglione';

  license_gnu;
  run \&main, \"Ice cream chooser";

  sub main {
    print "Ice cream is $ice_cream.\n";
    return;
  }

It can be run from a command line as:

  icecream -i "Lemon sorbet"

To get a GUI for choosing the value of -i (and any other values), you
just run the program without any options:

  icecream
