Just define a pnm-file and then add specialized methods on
three generic functions: initialize-io, deinitialize-io and
write-event.  look at the files src/sco.lisp, src/clm.lisp
and src/cmn.lisp for how its done.

id be curious to read about the pnm format if you would
send me a url to a description.
