Subject Re: Dynamically creating datasources
Date Fri, 07 Jul 2006 20:58:01 GMT

I don't mind doing some more legwork, but I could really use a nudge in 
the right direction. Aaron mentioned that I could use the console code as 
a template for what I'm doing. Can someone point me at the right place to 
look in the source tree? I did a little bit of poking around, but I got a 
bit lost trying to figure out which module to begin searching.
