I hacked up a quick script this morning to handle the new elog scripts
in 2.1. Perhaps some of you can make use of it or help me improve it.

Thanks,
Donnie

I also have a partially completed utility for this, which I had intended 
to complete when my final exams ended. I'll include it here as well in 
case anybody wants to play with it. If nobody has a preference wither 
way, I'll do some more work on this when I get home from college in a 
day or two.

Please understand that this is incomplete code that doesn't yet work 
without some tinkering, and I haven't touched it in a few months because 
of school work. I'm just sharing what I've already got in case anybody 
is interested.
