When I enter "pkg describe -verbose image" I obtain a long list of functions, some of which actually don't exist. They are:
imfinfo

What has happened to these functions - were they once in the package but have been removed in the latest release? And if so, is there any way I can obtain them?
Opps, that is in fact a bug in the "pkg describe -verbose" command. The packages INDEX can perfectly well have function names in it that don't exist. That was a deliberate choice so that it might be used to note equivalent functions of matlab that Octave doesn't have, and in particular note this in the function reference on the website. For example see the roifill and roifilt2 functions on
http://octave.sourceforge.net/doc/image.html
Now the "pkg describe -verbose" command just uses this INDEX file as well and prints out the contents. If the INDEX file was automatically created by the "pkg install" command this is not a problem. However, hand written ones like that for the image package aren't. Not sure of the best solution for this, but note that the function reference section of the octave-forge website is a better source for the type of information you are looking for.
Cheers
