iCalendar, Project Management, Agenda, CVS and Perl?

parasew asks: "I am searching for Web-based Project Management Software, which should be (mod-)perl based, so I can enhance it or put it into an existing environment using MovableType, which is in a sort of alpha-state. I found a site about Call Center, Bug Tracking and Project Management Tools for Linux and also this short listing, but sadly they are just a bunch of projects which only come close to the kind of tool I am searching for. Gantt and Chronos, seem to be a very nice Web-Calendar packages written in Perl. I was just wondering why no one is using iCalendar (does anyone know of Perl-based Software using iCalendar), as most of the Agenda Software uses iCalendar, and even Mozilla Calendar is capable of subscribing to remote-Calendars. This looks very interesting to me. In general, I wanted to ask you Monks for the best way to do this. Should I create a new app from scratch or reusing existing stuff?"

"Here are the features I am looking for:

• The use of Calendars (multiple users) and iCalendar Support
• File-Pool for projects (CVS-based or similar)
• Progress-bar for showing the current state of a project
• A public calendar where users can publish events from their private calendars

I found a simple Calendar script from PerlMonks, and another easy one here. Of course, there are really lots of Calendar scripts out there, but I am asking you for hints. Which ones do you know of that comes close to my needs? There are several existing Modules for iCalendar on CPAN, and i thought about reusing stuff to maybe create a dirty hack of Chronos, Bricolage and add the CVS and iCalendar support on my own.

Thanks for any help, hints or suggestions."
