Yeah, I think Bill's reply was really meant for Jason directly, but no
problem.  AFAIK there's a thick layer of drivers between a RasPi
application program and the GPIO pins.  The code I've actually seen has
used cat or echo to write text to magic files (under /dev , I think?)
for the purpose of opening access to pins and sending and receiving bits
on them.  There's a lot there I still need to learn.
