MacOS X Log Monitoring

I just discovered FileMonitor and it's just the thing for monitoring log files. I set it up to watch my Apache access and referer logs, and I was buried under reports of my own local browsing. So I set up a couple of simple filters to remove myself from my logs, and the results are wonderful. Now I just need to write a little grep routine that does the same thing, then pipe the results into some HTML for an online referer log.
