# because it uses the "multiprocessing" python module instead of "threading"
# module, it can scale to many cores
# all the heavy lifting is done in "invocation" module,
# this script just adds code to run multi-process tests
# this script parses CLI commands, sets up test, runs it and prints results
#
# how to run:
#
# ./smallfile_cli.py
