+#!/bin/bash
+#
+# Put the .git submodule folder back to the right place.
+#
+# When initializing a git submodule, git usually puts the
+# submodules' .git folder inside the .git/modules folder
+# in the parent repository.
+#
+# While this keeps all submodule metadata in a single place,
+# it may not be confortable when you also want to develop
+# the submodule.
+#
+# This plugin simply moves the submodules' git folder back
+# to the standard place.
+
+# Parameters
+BASENAME="`basename $0`"
+MODULE="$1"
+
+# Checks
+if [ -z "$MODULE" ]; then
+  echo "usage: $BASENAME <submodule-path>"

+elif [ -d "$MODULE/.git" ]; then

+elif [ ! -d ".git" ]; then
+  echo "please run this command in the top-level repository folder"
