  Actually the components are hard-coded in the program, so to change them,  
you need to recompile ktechlab. That's a huge problem, imo.

  I think the models can be also defined in XML; I've mentioned this on the  
list earlier:
some 'basic' components should be defined in the program and everything  
else threated as subcircuit. So in XML we should describe two things: the  
symbol for the new component and the equivalent subcircuit as the model.
  As I know, spice does something similar: there are some basic parts, and  
the more complex ciruits are threated as subcircuits.

  Things get tricky when we want to define some interactive components with  
XML. For that we might need some expression-evaluation algorithms.

  BTW Wiki: can the wiki made read-only for not registered readers? When I  
look at the recent changes, I see 99% spam / spam deleted.
