 Replying to [comment:21 simonpj]:
 > We should both make the user manual reflect this, and fix any bugs
 (which surely exist).

 I'm just pointing out that "make the user manual reflect this" and "fix
 any bugs" are two actions which require very different sets of abilities.
 I //might// be able to do the former, but definitely not the latter. Given
 that, perhaps we should wait until someone with the competency to fix the
 latter comes along, and then we can update the users' manual at the same
 time.
