Checking them in now.

Also, tokenizer.py probably needs to have the new tokens += etc. added manually.

Okay. I'm not entirely sure how to do this, but I think this does it: replace

Operator = group('+', '-', '**', '*', '^', '~', '/', '%', '&', '|', '<<', '>>', '==', '<=', '<>', '!=', '>=', '=', '<', '>')

with

Operator = group('+=', '-=', '*=', '%=', '/=', '**=', '&=', '|=', '^=', '>>=', '<<=', '+', '-', '**', '*', '^', '~', '/', '%', '&', '|', '<<', '>>', '==', '<=', '<>', '!=', '>=', '=', '<', '>')

Placing the augmented-assignment operators at the end doesn't work, but this seems to do the trick. However, I can't really test this module, just check its output. It seems okay, but I would appreciate either an 'okay' or a more extensive test before checking it in. No, I can't start IDLE right now, I'm working over a 33k6 leased line and my home machine doesn't have an augmented Python yet :-)
