Google saved my ass

I needed to find out where in the sea of software that's the OPML Editor I'm installing a listener on port 5335. It should be easy, set a breakpoint in the inetd.startOne glue script and give me a stack crawl when it's opening that port, and it's not impossible, but it was easier to just give the string to Google and see what came back. It was a long shot and a couple of years ago it wouldn't have worked, but today it did. I found out which root file was making the request and from there it was a simple search to find the bit of code.
