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

I take that if you do want to name a submodule differently from
its (currently in-tree) path, you would do something like...

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

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

Sounds very sensible.
