Why don't you use plain ascii?  It's so much easier.....

I have never seen a formal spec, but I never really looked.  I 
don't follow the advertisements, so before you asked I didn't 
know it had a name.  I have always considered the Spice "ascii 
rawfile" format to be unnecessarily complicated, something we 
would be better off without.  Looking at the file, it's clear 
what it is.  It has extra baggage that only makes it more 
difficult to generate and read without any real benefit.

Werner suggested looking at NGspice source.  To see what spice 
does, I prefer looking at the original from Berkeley.  NGspice 
has some arbitrary changes that are not necessarily 
improvements.  

So, what are "your own tools"?
