Re: gEDA-user: Problem with spice model in both ngspice and gnucap

[Dan McMahill <dan@xxxxxxxxxxxx>]

I'll let Al correct me if I'm wrong, but it seems to me that at this 
point with gnucap plugins that it should be pretty easy to make a pspice 
compatible poly source for gnucap.  The other possibility, although I 
haven't dug out the right docs to know for sure, is that you can 
translate that bit to something gnucap or ngspice does support.
