git submodule remove?

I notice that in git-submodule, there is an "add", a "status", an 
"init", and an "update" command, but no "remove" command.

I have "git version 1.5.4.4", and man git-submodule provides no mention of 
the right way to remove a submodule.  I imagine that removing it from 
.gitmodules and rm -rf'ing the tree that git-submodule cloned should do 
the trick. Is this documented somewhere?
