gEDA-user: How to create my own parts?

[David Logan <djlogan2@xxxxxxxxxxx>]

Good morning. Is there an example of creating a ngspice'able symbol 
somewhere? I'm reviewing the documents, but never having set up a 
symbol, nor making anything ngspice compatible, I'm finding the 
documentation confusing.

I would like to set up symbols to match the various parts I am starting 
to accumulate. Diodes, transistors, transformers, that sort of thing. 
I'd also like to be able to run ngspice without having to edit my 
circuit file each time.

Any places to look?

Thanks,
David Logan
