 Many tools with a Cabal like interface (e.g. darcs, git, subversion,
 perforce) support

 {{{
 <program name> help [<command>]
 }}}

 where leaving out the command gives the same behavior as

 {{{
 <program name> --help
 }}}

 Supporting the same interface as may other tools would be nice for new
 users (who are likely to type help!) and experienced users as well (same
 syntax for all your tools). The first, and probably easiest thing would be
 to just support 'cabal help' but I would be nice with 'cabal help
 <command>' as well.
