additional pkg functionality - update command

[Thomas Yengst]

I'm new to Octave, but have 10 years of Matlab experience. I would like to see 
functionality in the pkg command to check whether each installed package is the 
most up to date. 'pkg list' nicely shows what is installed. Has anyone thought 
of adding the capability to do something akin to 'pkg update' whereby the 
current installed version is compared with the latest on octave-forge

? If not and people think it's a worthy functionality, I guess I'm volunteering 
to develop it.

cheers,
Tom
