Re: gEDA-dev: gnetlist as one way path?

Lossless... well close...

right now if i put in a netlist that has in the following order

net1 u1-1 u2-1
net2 u1-2 u2-2
net3 u1-3 u2-3

I get the following output and I have to run a do nothing middle script 

net3 u1-3 u2-3
net2 u1-2 u2-2
net1 u1-1 u2-1

I think this could be considered lossless but reversed.

As always this work is derived from gpl code and as such if any one
wants it let me know i will pass it on under the gpl.

As a warning it only builds against my modified libgeda.
