I did take a gander at its source about 6 months ago, but came to the conclusion that I wasn't grokking the overall picture well enough to even dot an i or cross a t in it. :( 20 years ago I would have barged right in and played that famous bull in a china shop. Then I learned that if I broke it, I got to keep all the pieces. :) Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
