I tried running compileall.py from IDLE with Python 2.4c1
(WinXP, SP1).

I get the following 'error':

....

Shouldn't an integer value (e.g. 0) be returned by
sys.exit?
It's nice that you can see where the script has ended,
but I think it's good to be more elaborate that
everything went OK. I think some users might think it's
strange to get a Traceback when everything is ok.
