Compressed Archive:

Clearly not the bleeding edge, but sure to be stable, compressed archives of major releases can be found in the downlaods folder. These archives include both source, documenation, compiled jar files, and scripts to make running easier. See README and the various documents in the doc folder for more information. This file can be opend in Windows with WinZip and under *nix by typing:
tar xzvf fileName.tgz

Current code on CVS:

Unlike other projects the code on CVS should always compile and run, and most likely not throw any exceptions (it's Java, no crashing here :)). If you are Sea Wars developer you can grabs the latest sources by typing:

export CVS_RSH=ssh;
cvs co sw4;

If you would like to download the sources anonymously type:

cvs -z8 co sw4
