# Wrapper around rpmtests that adds a couple of useful options/overrides:
#   -C, --directory DIR
#       like original -C but loads atlocal from script's directory if missing
#   -L, --log
#       print the test log when done
#   -S, --shell [CMD]
#       create an empty test and run a shell (or CMD) in it
#   -R, --reset
#       delete the test created with --shell
