I've been using the documentation from this project: http://qucs.sourceforge.net/ -- Actually, I had not looked at where that paper had come from before, maybe we can use parts of their software too! [[ reads site more ]]... It might actually be the case that it makes sense to merge projects... They seem to be trying to re-invent ktechlab where we have a great gui and they seem to be super-geniuses when it comes to simulation....

I care far more about bugs and essential features than speed at this point. -- New president: Here we go again... Chemistry.com: A total rip-off.
