Lil' help: Want to notify on *specific* console message

[UncleFoobar]

Hello;

I am a QuickSilver and Growl user.

Trying to figure something: i want to monitor
the Console and, upon a specific event happening,
have growl pop a notice to me.

(Has to do with some intrusion detection)

Where is the best place to do this/what tools?

AppleScript?

Foob, thanks for the ideas
