Hi Felix,

thanks, this sounds great!
I will try the Python update soon. I also looked a bit more into Swig and
it looks interesting to learn more on it. The original problem why we
started looking into Python though might be interesting to recall:
The Python libraries for plotting data are very interesting. The Python
exentension could make it easier to plot:
* i-v curves of devices
* transient simulation of e.g. logic circuits
* AC frequency sweeps

While circuits and simulations can be easily defined with Gnucap, the
plotting is something I want to refresh for myself for some basic
circuits...

Nice day,

Patrick
