Hi Nicklas,

including additional attributes in the netlist requires that
1. the netlist format in question has a way of representing extra 
attributes and
2. the netlist backend supports including extra attributes in the 
generated netlist.

The tEDAx netlist format supports "tags" on a components[0] which can be 
used for extra attributes, and the tEDAx backend in gEDA/gaf implements 
this.  By default, only the footprints= attribute is included in this way, 
but the list can easily be changed (see line 73 in gnet_tedax.py[1]). 
For example, if you wanted to include the customattr= attribute in the 
netlist, you would change the line

-        for attr_name in ['footprints']:

to

+        for attr_name in ['footprints', 'customattr']:
