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.

I think this is just a fact of life when using IDLE to run
scripts designed for command-line use.

The script is question is fine and represents good coding
style.  The only question is whether IDLE should handle
system exits differently.

Kurt, please pronounce and close.

From compileall.py:155 :

if __name__ == '__main__':
    exit_status = not main()
    sys.exit(exit_status)

IDLE traps the sys.exit() because quitting IDLE is 
usually not what the user wants to do when it's
encountered in the user's program.  

compileall.py is exiting with a False status, equivalent
to the conventional UNIX success return of zero.  You
could take it up with the compileall.py maintainer, but
to me it's no biggie.  In any case, IDLE is working as
designed.

You can actually run this by 
$ idle -r compileall.py

It will end up in the IDLE shell when finished, just close
the shell  :-)

Works on Windows, too, but the pathnames are more
complicated because IDLE isn't currently installed
correctly.
