There isn't as far as I know. That said, John Luciani has a nice perl
library for creating PCB footprints.

http://luciani.org/geda/pcb/pcb-perl-library.html

The gschem file-format documentation (in case you want it) is at:

http://www.geda.seul.org/wiki/geda:file_format_spec

There is something about the PCB format in the documentation which ships
with it. On my machine this is:

/usr/share/doc/pcb-common/pcb.pdf.gz

(You might need to copy that and use "gzip -d pcb.pdf.gz" to decompress
it, depending on your PDF viewer. GNOME's "Evince" which I use opens it
right from the compressed file with no problem.
