I'll send over some info tomorrow.  Shoot me a reminder if you don't
get it by the later afternoon.

I wouldn't really call it a schema...it's just a simple field
extraction bash script that then generates the sql inserts.  Like I
said...quick and dirty.

Afte coding it from scratch, I'm starting to like the idea of using
Splunk as a front-end to analyze the logs.  You may want to look at
using that rather than coding one by hand.  The free version can index
500 megs a day...which is a *lot* of queries.
