Packaging system

[Søren Hauberg]

Hi,
I haven't really worked on the package system in a while, because I 
didn't know what needed the work. Today I have however worked a bit on 
it. Now the system supports

*) Dependency checking.
*) Different installation prefix.
*) System-wide (if you're root) and local installations (if you're but a 
humble user) of packages.

I'm guessing the system still contains minor bugs (like all code), but I 
think it's just about done now.

I'll be happy to do some more heavy testing, write documentation, 
provide scripts to aid package writers/maintainers, etc., but I will not 
spend time on it unless there's a good chance of getting this included 
with Octave.

So I guess I need some feedback on what features are needed, etc.

As always you can get the system at http://hauberg.org/octave-package/ 
(direct download: http://hauberg.org/octave-package/package-0.1.tgz).

Thanks,
Søren
