<P>
Here's what <tt class="module">optparse</tt>-based scripts usually look like:
<div class="verbatim"><pre>
from optparse import OptionParser
[...]
def main():
usage = "usage: %prog [options] arg"
parser = OptionParser(usage)
parser.add_option("-f", "--file", dest="filename",
help="read data from FILENAME")
parser.add_option("-v", "--verbose",
action="store_true", dest="verbose")
parser.add_option("-q", "--quiet",
action="store_false", dest="verbose")
[...]
(options, args) = parser.parse_args()
if len(args) != 1:
parser.error("incorrect number of arguments")
if options.verbose:
print "reading %s..." % options.filename
[...]
if __name__ == "__main__":
main()
</pre></div>
