-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
This patch adds handling of modules.
Fixes up lots of --help and man pages to match reality
Adds disable/enable module handling
Lots of bug fixes
If you want to discuss sections we can do that. Breaking it up into
several different patches would be difficult now. But if you take the
easy stuff, We can discuss more difficult sections.
