You can now get SquidLib, a Java roguelike library as a released bundle or the daily source.
The releases are solid versions which have at least one game built with each. The daily source includes example and test programs in the source.
https://github.com/SquidPony/SquidLib/releaseshttps://github.com/SquidPony/SquidLibThe whole thing is licensed with Apache 2.0 which means you can freely take bits out and do whatever you want with them.
Current experimental portions of 2.0a1 include a bootstrap class that allows for using the library with no knowledge of Swing, expanded graph structures, and dungeon generation.
