Hi Glenn,


I have a few questions about your patch series:

- You introduce "sim" (for simulation) and "ab" (for PCB) as predefined 
contexts but state that user-defined contexts could be used, as well. 
What kind of user-defined context would make sense with this system?

- In what kind of situation would you want to use the "bypass" action?

- In what kind of situation would you want to use an external script, and 
what kind of modification would it do on the netlist?

- What is the "order" parameter used for?

- What does the patch to "s_slot.c" / the code in "sab.c" do?

What is your incentive to do this?

This would be

   #include "libgeda_priv.h"

for libgeda code and

   #include "gschem.h"

for gschem code.

Also, I missed one thing before:  All C source files must have

   #include <config.h>

as their first include since other headers may define different things 
depending on macros define here.
