+"""Extend OptionParser with commands.
+
+Example:
+
+>>> parser = OptionParser()
+>>> parser.usage = '%prog COMMAND [options] <arg> ...'
+>>> parser.add_command('build', 'mymod.build')
+>>> parser.add_command('clean', run_clean, add_opt_clean)
+>>> run, options, args = parser.parse_command(sys.argv[1:])
+>>> return run(options, args[1:])
+
+With mymod.build that defines two functions run and add_options
