JSauer is a little Java library that I've been working on. It's designed to connect to and receive information from Cube 2: Sauerbraten servers (it was designed to be used with the Justice Edition of the game). I myself find this extremely useful, and I am eager for any feedback. The download and documentation can be found here: http://www.chaos95.net/?page_id=77. The source code, along with an example file, is included in the download. Note that this is more of an alpha version and is subject to much change.
