kvigall

kvigall is a calendar program capable of showing calendars created from scripts that you create. If there's a site that you often check for upcoming events, you can create a script that crawls and parses this site. By converting your resulted data into a format understandable by kvigall, you can then view the info in a calendar. You can download version 0.1.0 here.

kvigall can also be found in the Python Package Index.

kvigall has its branches at Gitorious; see http://gitorious.org/kvigall.

Mods
