This is a simple hack which get commit metadata out of a Subversion repository and generate an iCalendar file containing all commits of a given author. I used it back then to visualize in a calendar my commit activity. Nowadays this script is quite useless as services like Ohloh and GitHub provides great timeline and activity streams. But this script can still be useful for private repositories.
And in the same spirit of this script, I uncovered
a script that look in a maildir folder for mails sent by a particular author,
then generate an iCal file based on mail dates.
