Humberto Massa asked about how to get stated hacking CGI.pm for Perl 6. To answer his question, I've enhanced some of the Perl 6 wiki pages. The download page is cleaner now and I've added a new page on getting started with Perl 6 module projects. Mostly you need to know to use
util/prove6 to run your tests with, instead of prove.
If you have further questions use the mailing lists or IRC to get in touch with the team.
