  15 # Test setup:
  16 #  -create a repository in directory lib
  17 #  -add a couple of files
  18 #  -add directory lib to 'superproject', this creates a DIRLINK entry
  19 #  -add a couple of regular files to enable testing of submodule filtering
  20 #  -mv lib subrepo
  21 #  -add an entry to .gitmodules for path 'lib'
