Re: Feature, implement :main command

Might as put :main in, as long as :m still abbreviates :module. Committed, :m is still module.

Don't forget to update the User's Guide too. Attached is a patch which updates the user guide. I couldn't get the user guide to build at all (docbook seems way to complicated for me), so I can't test that this doesn't break the userguide. I'm also not familiar with the docbook conventions/commands so I would appreciate someone checking that this is correct.

Thanks Neil
