A quick and dirty command-line processor. See main.py for more.

1. Copy main.py into your project.
2. There is no step 2.

See main.py, but in brief:

b.py:

import main
import sys

def callback(params):
  print "Called with " + params['foo'].value

m = main.mode("run", callback)
m.option("foo")
m.description="How not to be seen"
main.process(sys.argv)

Called as:

$ python b.py

Outputs:

Usage:
  # How not to be seen
        b.py  run --foo=<foo>

Called as:

$ python b.py run --foo=bar

Outputs:

Called with bar

Most of the work, including:

• Errors will be caught and redirected to usage messages better
• Options will have default arguments.
• The top-level mode will become unnecessary.
• Non-option arguments will be respected.
• Param objects will support more information.
• Cheese will be eaten.

This code is in the public domain. Do as you will. Feedback and patches are welcome but not required.
