I have a working prototype already (attached). It's a copy of the osmond 
backend. Please note that I don't know anything about scheme, so my code 
may look strange.

The output is one-line-per-record with fields separated by tab. First 
field is record type. Things are announced before details are given, e.g. 
before listing pin attributes the pin names of the element is listed.

I couldn't figure how to:

- get a list of attribute names attached to a net

- access attributes attached to a net, other than its netname

- get a list of attribute names attached to a pin

Could someone help with these so I can make the backend more generic?

Once this works, as I'm already knee-deep in scheme I will probably 
bite the bullet and write a few other similar backends, exporting to 
lihata, xml, indented text and json (in this order of priority).

TIA,

Tibor
