This is going to sound nit-picky and I apologise for that. What is in the spirit of "released" for the purposes of the competition: is a library that has publically available source code repository, online documentation and has been around for a few years considered "released" and we can use the latest subversion code?

Background: it looks like this should be ok, since a few of the libraries linked to on the rules page are in this category (e.g. pyscumm) as well as code samples at pygame cookbook. I'm considering a browser-based UI for a game and want to use Django to get rid of the fuss of server -> browser interaction and to be able to supply a small webserver as part of the game download (therefore, no setup required). So everything's publically available and it's documented to the point that anybody could use it, but there hasn't been an official tarball made in 11 months.
