Sample code:
----------------------------------------
#!/usr/bin/env python
"""optexample
Example of using optparse
"""
import os
import sys
import os.path
import optparse
__version__ = "0.1"
USAGE = "%prog [options] <arg>"
VERSION = "%prog v" + __version__
def parse_options():
"""parse_options() -> opts, args
Parse and command-line options given returning both
the parsed options and arguments.
"""
parser = optparse.OptionParser(usage=USAGE, version=VERSION)
parser.add_option("-v", "--verbose",
action="store_true", default=False, dest="verbose",
help="Verbose output during operation.")
opts, args = parser.parse_args()
if len(args) < 1:
parser.print_help()
raise SystemExit, 1
return opts, args
def main():
opts, args = parse_options()
if opts.verbose:
print args[0]
if __name__ == "__main__":
main()
