[JohnD]

All, 

An initial release of the octave raspi package has been made and is
available from the website [1]

The raspi package is intended to provide Octave with the basic functionally
similar to the Matlab raspberrypi package.
It uses pigpio on the Raspberry Pi for communication, and is not intended to
be compatible with the low level communication of the Matlab package.
