In addition to the helpful answers that others have given, the PCB file
format is described in the PCB manual
(http://pcb.geda-project.org/pcb-cvs/pcb.html).

It's not required for laying out boards in my (limited) experience, but
I've found that making footprints for sockets and connectors etc. is
much more reliable using Emacs to edit and PCB to look at the
results. There are a couple of gotchas in the format related to
historical changes in the default units over PCB's history, so I
recommend tweaking existing an existing footprint: it's a lot easier to
work out what's going on!
