+When we fetch a package source we should also fetch any submodules. Since we
+will use the file protocol for git submodules we will need to explicitly enable
+it as it is disabled for security purposes.
+
+  $ export GIT_ALLOW_PROTOCOL=file
+
+This repository will be a submodule in our main repository.
+  $ mkdir someotherrepo
+  $ cd someotherrepo
+  $ git init --quiet
+  $ echo "world" > bar
+  $ git add bar
+  $ git commit -am _ --quiet
+  $ cd ..
+  $ SOMEOTHERREPO=$PWD/someotherrepo
+
+We create a repository for the package that we wish to build that has
+someotherrepo as a submodule.
+  $ mkdir somerepo
+  $ cd somerepo
+  $ git init --quiet
+  $ echo "hello" > foo
+  $ git submodule add --quiet $SOMEOTHERREPO mysubmodule
+  $ git add foo mysubmodule .gitmodules
+  $ git commit -am _ --quiet
+  $ cd ..
+  $ SOMEREPO=$PWD/somerepo
+
+  $ mkdir foo && cd foo
+  $ make_lockdir
+  $ cat >dune.lock/test.pkg <<EOF
+  > (version 0.0.1)
+  > (source (fetch (url "git+file://$SOMEREPO")))
+  > (build (progn (run cat foo) (run cat mysubmodule/bar)))
+  > EOF
+
+Building this package should pull in both repositories. At the moment this is
+not the case and only somerepo is pulled.
+
+  $ build_pkg test 2>&1 | sed -E 's|.*/cat|cat|'
+  hello
+  world
+When the above works it should act like:
+
+  $ make_lockdir
+  $ cat >dune.lock/test.pkg <<EOF
+  > (version 0.0.1)
+  > (source (fetch (url "git+file://$SOMEREPO")))
+  > (build 
+  >  (progn
+  >   (run cp -r $SOMEOTHERREPO/bar mysubmodule)
+  >   (run cat foo)
+  >   (run cat mysubmodule/bar)))
+  > EOF
+
+  $ build_pkg test
+  hello
+  world
