Francesco, I think that letter is good and grammatically OK, but I wouldn't 
relay on my
english. In my opinion there should be no  problems with license, spice is so 
old and
original code have been used so many times in commercial product (often much 
worse then our
ngspice).

    Now about spice itself.
I added new function "u2" to the B source. It is version of "u" that change 
smoothly from 0
to 1 and 1 to 0. I don't know why but standard "u" doesn't worked with my 
galvoscanner model,
I spend much time on it and finally changed the code. Do You think that this 
is right? Should
we solve problems in this way?
Anyway, "u2" works better then "u" in if-then-else expressions, so maybe we 
should keep it?

PS. "help" command does not work. It is funny because it worked in the past 
(in standard
spice). Who has changed help functions?
