[Orca-users] Script to generate point in time Orca graphs

I've been using drraw, but trying to get it to replicate all the same 
graphs Orca makes is difficult.  It's not really designed for that--it's 
designed to show you a graph of portions of your data.  You can save 
templates, and I suppose if I put the time into it to create a template 
that matched my orcallator.cfg, I'd be in business, but that's quite a 
bit of work.

I'd be interested in trying out your script as an alternative.  How do 
you tell it what orcallator.cfg file to use?

One question I have already -- Date::Manip is the bomb, and its UnixDate 
or ParseDate functions can take about 100 different date/time formats 
(including english phrases like "2 days ago").  Have you considered 
using that for begin/end date parsing?  (note: your usage output shows 
one date format, but your examples show that it can also accept
