A bit off topic, but worth noting, is that with the lates build, Perl/Tk is included in the standard ActiveState Perl distribution.

This will undoubtedly make it far easier for Perl programmers coding for the Windows audience to incorporate a GUI in their work. It's always been as easy as

   perl -MCPAN -e 'install Tk'

for *nix users, but getting your average Windows user to download the ActiveState installation executable then double-click on it can sometimes be burdensome.
