The thing you need from Spice-OPUS is the cmpp compiler.  It is used
to turn the .mod and .ifs  files into .c files.  It is also used when
making the codemodel .cm (shared-object) files.  It is not a part of
the tclspice code; rather, it is a compiler used to build the code.

What's the URL?  Does the stuff work?  The XSpice stuff in ngspice was
originally non-functional.

According to his e-mail of a couple weeks ago, Stefan has fixed the
GTRI cmpp & placed it in the CVS.

If I were you, I would try to keep all the changes I incorporated int
tclspice-0.2.10-sdb.  Not only is the XSpice stuff POLY stuff working
now, but I also made a lot of changes to the src/frontend/parser in
order to handle complicated netnames & handle embedded vendor
.subckts.  You can get my code from:

As Stefan said, do a diff -ru against your stuff to see what is different.
