Some libraries from Matthew Johnson: http://www.matthew.ath.cx/projects/java/ Modifications: - including precompiled native C libraries (libunix-java) for architectures: arm, amd64 and i386 - UnixSocket/UnixServerSocket now implements closable (allows try-with-resources usage) - Cleaned up code style - Split test classes to test classpath - Introduced JUnit - Removed the whole CGI package, it should never ever been used these days

The newest version!
