The only requirements are a version 1.4 of a jdk, and Ant. For reference, development is done on Sun Java 1.4.2_03, using Ant 1.6.0, under x86 Linux. Note that I currently only provide the source code, so you need a full jdk. Nicer binaries may be posted in the near future.
It's easy enough to get the sources.
tar zxvf tuxcourser-0.4.tar.gz cd tuxcourser-0.4 ant jar
java -jar packages/tuxcourser.jarAnd if that doesn't work, an even more failsafe way is to use ant instead:
ant runNote that "ant run" depends on the jar, so if you make any changes to the code, this is a quick way to compile and run all at once.
