Supported kernels:
Full functionality requires Linux 2.2.x or better. A large fraction of the
code should run on just about anything. While the current code is fairly
Linux specific, it should be fairly easy to port the majority of the code
- to, say, FreeBSD or Solaris, or Mac OS X, or even Windows (if you are into
