New release is coming soon. Down to a very small number of issues.
1) How does octave pick up that a new package is present after someone installs a octave-forge package via apt-get? I looked at the .deb file for octave-mapping as a simple example and didn't see a postinst script. But if I just simply put all the files in the normal locations, they don't get auto read into the path and the octave_packages file is not updated on the next launch. So, how does octave recognize that someone has installed the octave-mapping .deb file?
2) What is the lowest level function that gets called whenever any form of a plot is generated with gnuplot? Looking to do something after drawing is finished for any figure. Also, is there a way to have no plot displayed to the screen?
