title: How to install, verify and update all Octave packages at once?
body: <p>Today I have installed Octave 3.8 with GUI on my Windows 7 machine. Is there a command that will install all the available Octave packages ? Then I would also like to see a list of all the installed packages, and update them at times. So is there a command that checks for updates of all the installed packages ? Thank you.</p>
