gEDA is the GNU Electronic Design Automation suite. For a while in Summer 2006 I was employed to work on it by Cambridge University Engineering Department, although I still use it extensively and sometimes fix some bugs.
Recently, I was involved in the switchover to using git for version control. I have a personal repository where some of my changes get put to mature; it can be cloned from:
git://repo.or.cz/geda-gaf/peter-b.git
You are likely to be more interested in branches other than the master, which tends to track the main git unstable branch.
