  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'
