Spice Model

A non hijacked from "looking for a eagle part" -- I've been trying to make a spice Model for some time and succeed once but can't do it again. I have files for a TLC2274 but haven't been able to make a model for it. hopefully, when I'm done, It will show up in my C:\Program Files\Spice LTC\lib\sym\Opamps file as TLC2274 just like all the LT opamps.
Does any one have a simple step by step procedure or some place to send me?
Thanks,
Kinarfi
