test_description='Basic porcelain support for submodules
 
This test tries to verify basic sanity of the init, update and status
subcommands of git submodule.
'
 
. ./test-lib.sh
 
#
# Test setup:
#  -create a repository in directory init
#  -add a couple of files
#  -add directory init to 'superproject', this creates a DIRLINK entry
#  -add a couple of regular files to enable testing of submodule filtering
#  -mv init subrepo
#  -add an entry to .gitmodules for submodule 'example'
