So why do you inflict yourself the pain of rewriting all the parsing etc???

http://www.python.org/doc/2.4.2/lib/optparse-parsing-arguments.html:
"""
The whole point of creating and populating an OptionParser is to call
its parse_args() method:
(options, args) = parser.parse_args(args=None, options=None)
where the input parameters are
args
the list of arguments to process (sys.argv[1:] by default)
"""
what about something like :
line = myfile.readline()
options = parser.parse_args(line.split())
But what, if you prefer to rewrite (and maintain) a custom parser doing
exactly the same thing, please do !-)
