git-subtree is another option.  It was recently merged into contrib/.
Whether to use submodules or subtrees largely depends on the work style
of your group and how coupled the projects are to each other.
submodules requires a bit more day-to-day maintenance by the user (in my
experience) while with subtrees it's a bit more involved to push changes
from the combined repository back to the separate repositories.
