Olof,

you'll generally want symbols that match your footprints.  the symbols 
may be very specific, or very generic.  In any event, you want the pins 
on the symbol to coincide with the pins on the footprints.  pin 1 needs 
to match up with pin 1.

The symbols only need two attributes to go from gschem to pcb using 
gsch2pcb:  refdes= and footprint=.

you can use gattrib to quickly add footprints to the elements in your 
layout before running gsch2pcb.

you can see the script on Luciani's website to see how to force gsch2pcb 
to find a specific directory of footprints.

As for symbols, you can probably get what you need from the geda library 
included with the program.  you WILL have to check the pin-numbering 
though.  As a default each pin in a symbol should have:

pinnumber=#
pinseq=#
pinlabel=#	
pintype=<value>

usually pinnumber, pinseq, and pinlabel can all be the same, i.e. "1" 
for pin one on a chip or capacitor.

hope this helps.  there is file called the 'master attribute document' 
that's easy to find.

the gsch2pcb system seems really slow at first, but it will save you 
TONS of time down the road.

Phil
