Re: gEDA-user: bom2 gnetlist

["Ed & Angie S." <edangies@xxxxxxxxx>]

Bert,

Thanks for your response.  I've been looking at the various back end files 
and some language tutorials.  I tried guile in interactive mode per the 
"gnetlist user guide" and displayed the packages and all-unique-nets 
variables for my schematics.  I'm learning a bit but it seems like I would 
need to know what variables are available and maybe what functions are 
provided by gnetlist to the backend routines.  I may be able to get most of 
what I need from the existing backend files but I was wondering if there is 
a reference for such things.  Or, does the real programmer go to the 
gnetlist source and figure it out.  I'm more of a hardware person but if 
that is how it's done then I'll get there.  If there is an easier way I'm 
all for that too.

Best Regards,
Ed Schurig
