[Spice_discussion] PySPICE

[Bridgman, William T.]

I just checked the github site and have seen no revisions to this  
package.

I've done a few more experiments with this original version and expect  
to write a module that will more tightly couple SPICE to some of my  
existing python pipelines.

Are there any major interface changes for this wrapper pending Real  
Soon Now?

Thanks,
Tom
