The Subversion repo (http://svn.wikimedia.se) on Glesys1 contains code for Drupal extensions. If it isn't kept anywhere else, it could be imported to Github. git-svn could be used for this.
I poked around a bit, but couldn't figure out how to clone it with git svn.
I managed to make a Git repo from this. It's up on https://github.com/Wikimedia-Sverige/drupal-glesys.
