Well, that's a bit incorrect.  SVN doesn't offer a way to do this 
either.  We use a 3rd-party script that runs as a pre-commit hook.

I never liked this, and intended to tighten this up at some point, but 
never got around to doing it.

It's more like core devs have access to all of the core of Xfce, with a 
few small exceptions.

Sure.  If everyone is willing to be good citizens and respect module 
maintainers' commit policies, I'm ok with this.  I don't think it'd be a

Eh.  This means translators have to set up their own public repos, 
right?  That's not really a burden I'd like to impose on them.

Well, sorta.  I'd think it only needs access to the stuff it actually 
has to change.  I mean, if it's never going to commit outside of po/ and 
maybe, there's no need to grant it permission to touch 
anything else.

Yeah, I'd briefly thought about using Gitorious for the whole thing, but 
kinda dismissed it, but not for any good reasons.  I'll look into that. 
  I think it uses a similar approach for authentication that my 
homegrown crappy git admin interface uses (you upload ssh keys), which 
is good and bad.  I kinda like the idea that you can easily log in just 
with a plain password if you want to.  But maybe that's not such a big 
deal (hell, I never do it, anyway).
