Re: BGP REGEXP

There's a reason why it's referred to as "Internet Yiddish" in some
circles. It's still better than TCL though. I'm going to have to
disagree with you on GREP though. GREP is one of this rare and beautiful
gifts life gives you, like puppies and sunsets and screen. and vim... God
I need to get out of my basement...

heheheh... Once upon a time I decided I was going to teach myself perl
(as I'd done with quickbasic, turbo pascal and C++ many moons ago). I
bought a few books, and got about half way though one of them and
decided "F#*$ this" :)

PERL (like GREP which brings us regular expressions) was created by Satan.
