I'm a damn fool, of course, because this resulted in nearly a 20 meg file of error messages. Sigh.
It occurred to me that I could probably use a little filter just to sort through all the errors...and then I remembered what I said to myself, last night at Borders, looking at that copy of Mastering Regular Expressions (second edition, of course):
"I don't need hardcore regular expressions. Regular expressions are a little scary sometimes, and I'm fairly comfortable with where I am with them."
If stupidity were a crime, I'd be in lockup right now.
So, off I go to start fixing errors, one by one, until they're all gone.
