[m463]

I do the same sorts of things for my scripts.

I start with my "template" script and fill it out.

totally over-engineered for most tasks, but then as the tasks mature they have a firm foundation.

very simplified example:

    #!/usr/bin/python
    import sys,os,argparse

    parser = argparse.ArgumentParser(argument_default=None)
    parser.add_argument('-d', '--debug',     action='store_true',  help='debug flag')
    parser.add_argument('files', nargs='*',  default=[],           help='files to process')
    arg = parser.parse_args()

    def die(errmsg,rc=1):
        print(errmsg, file=sys.stderr)
        sys.exit(rc)
    
    if not arg.files:
        die('filename required')
