+#!/bin/sh
+#
+# This is a test script to demonstrate that the changes about
+# 'core.submodulesfile' do not cause regressions and even work as intended
+# when a custom gitmodules file is specified O_O.
+#
+# The script patches the hardcoded '.gitmodules' occurrences to be overridden
+# by an environment variable.
+#
+# Note that 'core.submodulesfile' affects no only the 'submodule' git command
+# but many other git commands that directly or or *indirecly* use the
+# submodules_file variable.
+#
+# In particular all the commands that use unpack_trees(), like 'am', 'clone',
+# etc. are affected.
+#
+# Anyways this is not a problem because the option is passed to all git
+# commands in the "./bin-wrappers/git" wrapper script.
