8 This test tries to verify basic sanity of the init, update and status
9 subcommands of git submodule.
16 # -create a repository in directory init
17 # -add a couple of files
18 # -add directory init to 'superproject', this creates a DIRLINK entry
19 # -add a couple of regular files to enable testing of submodule filtering
21 # -add an entry to .gitmodules for submodule 'example'
