gEDA-user: pcb -> shell command

[Tom Schouten]

hello,

i started using gEDA tools last week to design a small PIC board. 
it looks like a nice suite! finding out gschem uses guile, and 
PCB files are as good as compatible with scheme 'read' made me smile :)

i was wondering though if it is possible to use PCB to directly invoke 
external shell comands, without using them to read or write stuff. basicly 
what i want is to invoke 'make' from PCB, and subsequentally reading in some 
files. i didn't find anything about this in my first read of the PCB doc.

cheers
tom
