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 to an admin: I don't know if there is a more appropriate category for this post, but if there is - please move it there if possible! :)
