Re: Notes on Using Git with Subprojects

One thing that I believe some people have requested for subprojects is
to avoid downloading files/history for subprojects you're not interested
in.  I think this could be faciliated in this scheme by only cloning the
heads of the subprojects you're interested in (there would need to be
special machinery to handle this at the root level if we want to allow
making root commits without necessarily having all of the subprojects).

In what I'm suggesting, commits are local to a project's working 
directory repository and are pushed somewhere else to be recorded long 
term. Since projects are stand alone, possibly with dependencies, 
working on a (sub)project without having other associated (sub)projects 
is accomplished by checking it out.

A first step to this would be an argument to git-clone to allow cloning
only a subset of refs.

Something like this?

	git-init-db
	git-fetch <repository> <refspecs>
