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

[Steve Meier <smeier-at-NOSPAMalchemyresearch_dot_com>]

more like:

> backnet -f pads_net -n in.net -m pads_eco -e empty.eco -g pads -o
out.net

Where 

pads_net is the script for importing the pad style netlist

in.net is the actual pads style netlist

pads_eco is the script for processing a pads eco file and usin it to
modify the libgeda structures. In this case we are feeding it an empty
eco file so there will be no changes.

empty.eco is the empty eco file

pads is the script for taking the libgeda data structure and generating
a pads style netlist

out.net is the output pads netlist

then out.net == reverse(in.net)
