Hmm.... I was thinking that the extra "path" level could be optional,
i.e., if there is no path.$path.submodule, then the name of the
submodule would simply be $path.

Yeah, that should also work out. Time for a quick poll?

Ack. I think the natural thing for a lot of cases is the trivial "module 
name == path" case, so having to have

	[path "kernel"]
		module = kernel

for that case just sounds unnecessary.

That said, I wonder if it wouldn't be more natural to do things the other 
way around, because quite often a "module" (under CVS conventions) is a 
*set* of directories, so with that in mind, it might be better to have the 
mapping be something like this:

	[module "infrastructure"]
		submodule = lib
		submodule = build

	[submodule "lib"]
		url = git://xyzzy/lib-1.2.3

	[submodule "build"]
		url = git://xyzzy/build-0.61


and make the rule be:
 - submodules are named by their paths (ie "path == submodule")
 - a module is a set of such submodules/paths
 - if no "module" is defined, the default is to just use the 
   path/submodule name

IOW, in the above case, we have *three* modules:

 - module "infrastructure", that is the union of submodules/paths "lib" 
   and "build"
 - module "lib" (== submodule/path "lib")
 - module "build" (== submodule/path "build")

and when you do a 

	git submodule checkout infrastructure

it would be basically equivalent to

	git submodule checkout lib
	git submodule checkout build

Hmm? That's how CVS users use modules (ie the "src" module may be much 
more than a single subdirectory)
