Gentlemen,

Unluckily there is more to this than just the graphical entities themselves. A 
fully IEC compliant CAD does more than have a library adhering to the canonical 
graphical entities. The standars actually define line widths, symbol sizes, line 
spacing and whatnot. I am not an expert in this. Actually, I admit being 
completely ignorant about this. What I know is that SPAC by SDProget conforms to 
the standards, or at least it claims to do so. Because of this, it is currently 
easier to produce conforming documentation with SPAC than with gschem.

Actually, from my point of view this requirement is more important than the 
perfect imitation of IEC graphics, so long as the symbol is easily recognized.

Well, gentlemen, if there is any additional input I can provide to help the 
project, just drop me a line.

Alex
