Spiceprm was written in the course of moving my engineering activities to the Linux operating system. My previous MSDOS spice package permitted passing parameters to subcircuits. The raw Berkely Spice doesn't. Anyone used to this feature knows the frustration of trying to use a simulator without it. This script is the result of my desperation. It translates a circuit file containing parameterized subcircuits with math expressions into another circuit file meeting raw spice requirements. You then run spice on the translated output file.
