Bygfoot is a small and simple graphical football (a.k.a. soccer) manager game featuring many internat. leagues & cups. You manage a team from one such league: you form the team, buy & sell players, get promoted or relegated and of course try to be successful.
In approximately 10 days there will be new releases for both the stable and the development versions. The new stable version contains some minor bugfixes, the unstable version features extended stadium enlargement options and the possibility to fire players. It should also run a bit faster on slow systems.
Probably there won't be any deb packages anymore for Bygfoot on the SF.NET site, because the stable version of the game is available on Debian servers now. You should be able to install it with apt if you have an unstable source in your sources.list file. You can also get it from http://pulsar.unizar.es/~isaac/debian . If you'd like to test the development version, you have to compile the source package yourself or use the bin version.
