Comment 1 for bug 1548848

Hi Christian,

are you aware of my experimental netlister branch?

   http://thread.gmane.org/gmane.comp.cad.geda.user/47097/

   A subsheet symbol can have one ore more "subst=NAME=VALUE" attributes.
   Inside the subschematic, any occurrence of "$(NAME)" is replaced with
   "VALUE". This only works for attribute retrieval from packages; in
   particular, it isn't possible to change slotting or subsheet source
   files this way.

Since I didn't receive much feedback about it (the discussion almost
instantly drifted off in another direction), I didn't spend more time on
the feature and didn't merge it into master. If you are interested in it,
I'd appreciate if you could give the code a test.
