septic is a project hosting solution primarily developed for hosting open source software developed by myself integrating with GIT and mailman.
Why not? This all started out as a project for me to get GIT repositories up on the net easily as I didn't know of any other tool for that at the time.
Currently there are a set of other tools providing about the same functionality but all with different focus but as this is all for the fun of it I haven't yet seen a reason to stop developing this site.
