Hi DJ,
Thanks. As usual, after I sent the email, I saw help in the tutorial  
in the next paragraph. Now when I execute:

$gsch2pcb -v project
..
..
.----------------------------------------
    Variables which may be changed in gafrc:
    ----------------------------------------
    gsch2pcb:pcb-m4-command:    "/usr/bin/m4"
    gsch2pcb:pcb-m4-dir:        "/usr/local/share/pcb/pcb/m4"
    gsch2pcb:pcb-m4-path:       ("$HOME/.pcb" ".")
    gsch2pcb:m4-files:          ""
..
..
..
The gsch2pcb:pcb-m4-dir: is not correct for my system. You wouldn't to  
happen to know the gafrc syntax for setting the pcb-m4-dir do you? I  
vaguely remember lisp.. it is something like
(setq gsch2pcb:pcb-m4-dir "/usr/local/share/pcb/m4")

and I will look into the pregenerated libraries, although I am sure I  
am going to immediately need to generate my own footprints, so I think  
I will need to use the m4 program.

Thanks,
-Chris
