Thanx.

Btw, it was you who TL;DR'd. One part of my story was right about trying 
to extract attributes and netlist stuff with gnetlist That was the 
part that took incredibly long due to scheme. In turn this experience made 
me not even consider using it again for the other task which was coord 
extraction.

So next time I have something similar to solve, I will first ask you for 
the scheme code and only if that fails I do the dirty sch-parsing awk 
fewliner.
