Thanks,
I found this (http://codeendeavor.com/archives/535) nice wrapper for ASL and I
wanted to see how I could incorporate it in to my app. Since this is a
foundation tool I wanted to init it in my "myTestApp.m" main function, and be
able to call "[log info:@"Log Stuff"];" in any of my classes. I have never
really done this before. Should I just re-init it in each of my classes?
Thanks,
tom
