I looked at your site but it did not do *exactly* what I wanted.
Instead of modifying it I decided to try do it from scratch and
as that was succesful I didn't go back.

Improvements? I would need to consult my notes. I think my list had
adding NGSPICE's XSPICE extensions, i.e. add string attributes, vector
format for pins, support for bus lines, and automatic insertion
(or optimizing out) of ADC and DAC bridges. A few of these need
gschem extensions (or features I didn't find yet), i.e. callbacks
to user (or netlister) code when chosing / placing components so
that a symbol can be dynamically build.
