don't use sys.exit(...) inside main(), but only under if __name__ == "__main__"
The convention is that sys.exit(...) is called only if a module is run as a script,
and that main() entry points use return statements to report exit codes: 0 (or None)
for successful execution, or any non-zero integer for errors.

E.g. see the console scripts generated when installing with pip.
