I've created a calendar of PAX East events. You can view it, and get a link to the Perl script used to generate it, after the break.

And here's the Perl script used to generate it - you need to pipe in the PAX East schedule page. (Doing that is an exercise for the reader.)

Also, the generated iCalendar file, which includes broken UTF-8 sequences because I didn't bother fixing that in the Perl script. (You've been warned.)
