This is an updated version, which now includes that facility to e-mail
I have also tried it on my server and it works fine for me. I think
that some of the commands or modules require Python 2.3 or higher.
I have set it up as a cron job, so tomorrow will be the really big
test. If I get an e-mail with the stats, then I know my first Python
program really does work :-)
Again, let me know if you see any way this can be improved.
Also, is there someplace on Sourceforge that I can post this, so that
everyone can "enjoy" it too?

# envelope header.

s.sendmail(SENDER, RECPTS, msgMIME.as_string())
print "log file not found"

Life's journey is not to arrive at the grave safely in a well
preserved body, but rather to skid in sideways, totally worn out,
shouting "What a great ride!"
