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 lib
#  -add a couple of files
#  -add directory lib 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'
