help with an audit-packages shell script

[Philip <subs%christiantena.net@localhost>]

I want a shell script that I can cron.  I want this script to do an
audit-packages and send me an email if there is anything that needs
patching.  The script below works, except that it sends the email even
if audit-packages returns nothing.

Can anyone improve it?  the last two lines should be one line
thanks, Philip
