Bert,
Are you saying that any attribute defined in this "attribs" file shows 
up in the add attribute dialog list of attributes?

If so, that is a good way of adding custom attributes.
I did a system search for attribs* and got one hit:
/usr/local/doc/geda-gaf-1.8.2/examples/gTAG/attribs
I looked at it and has a series of attribute names, but I am not sure 
how that applies. I will have to do some research in the docs to see how 
I can use this.

Thanks.
Girvin
