Re: gEDA: symbol libraries and attributes

[Jonathan Hanson <hanson-at-NOSPAMphgrav_dot_phys_dot_lsu_dot_edu>]

Oh, awesome Carlos.  I'm an idiot, I should've know this sort of thing 
was in a rc file as an option, but I
never went looking for it.  Thanks a ton, that'll make my custom heavy 
library 10 times easier to use.

I'll be building a library of capacitors and resistors with all the 
standard values filled in, along with
some transistor symbols, if anyone is interested in that.  I don't know 
if submitting it to the official symbol
library is a good call, since my library won't jive with the light 
symbols philosophy.
