Thank you!!!!

I was just starting to look into doing  that myself, but if you 
can do it I can do something else.  Enabling gnucap to work in 
the qucs environment will be very valuable.

You shouldn't need to.

obsolete_callback() is a throwback to old code, made before I 
had thought of the concept of language plugins.  Back then, all 
parsing was done in the device modules, or in things like the 
"bm" modules, which modify the behavior of a parent device.

As of now, everything except the "bm" modules has been moved 
away from it.  Eventually, it will be removed completely, but 
that can't be done yet.

The missing pieces are the functions set_param_by_index, 
set_param_by_name, param_is_printable, param_name, param_value.  
They need to be added to the bm modules.  They will be 
eventually.  Some of the bm modules have arrays of parameters, 
which are not yet accomodated by the new system.
