WishPerl is a pair of two (small) scripts, one in Perl and one in Tcl, enabling you of painlessly breeding Perl modules with Tcl/Tk/Tix GUI. Works on Unix with perl 5.* and on Win32 with YeP-perl. Now works on MacPerl, too, with Tcl/Tk 8.0.4 and the Mac::AppleEvents::Simple and Mac::Apps::Launch modules.
With it's help, you can add Tcl/Tk GUI to your Perl program fast, or make a new application with GUI events processed by some Perl engine, or debug your Tcl script easily.
