#
# Test setup:
-# -create a repository in directory lib
+# -create a repository in directory init
# -add a couple of files
-# -add directory lib to 'superproject', this creates a DIRLINK entry
+# -add directory init to 'superproject', this creates a DIRLINK entry
# -add a couple of regular files to enable testing of submodule filtering
-# -mv lib subrepo
-# -add an entry to .gitmodules for path 'lib'
+# -mv init subrepo
+# -add an entry to .gitmodules for submodule 'example'
