gEDA-user: Library of gnucap and ngspice compatible models?

[asomers@xxxxxxxxx]

I, and judging from the mailing lists and forums many others, are
frustrated by the difficulty of finding spice models that are
compatible with open-source circuit simulators.  Common replies are
"you don't need that level of detail" or "find a model library buried
in the vendor's website, pick a model for a part similar to yours,
then alter any lines containing X and replace .subckt Y with a
reference to your Z".  But that's annoying, especially for users who
are new to these simulators.  I started collecting and adapting models
to be used with my program, http://mrfilter.sourceforge.net , but then
realized that the problem is much larger than my single app, and a
comprehensive library would badly bloat my downloads.

So my question is, should I make a new project which is a library of
models to use with open source simulators?  I think that there is a
need for such a thing, but would it be a good idea?  Licensing should
not be a problem; most vendors license their models to permit
redistribution.  Would it be better to incorporate these into some
existing project than to start a new one?  For that matter, has
somebody already done this and I'm just duplicating effort?  And
finally, what extension should a spice model's filename have?  There
sadly seems to be no consensus to that last question.
