The library symbols are starting points, developed for a variety of =
purposes by a variety of people. Some had no idea what the SPICE back =
ends need. In general, you need to make copies and tweak the symbols for =
*your* project.

The gnetlist back end at https://github.com/noqsi/gnet-spice-noqsi gives =
you much more control of SPICE netlisting than the =93spice=94 and =
=93spice-sdb=94 back ends. You can use the standard library symbols =
(with an attached attribute) with this back end.
