Proposal for Generic Metadata and Settings Modularization

On my side I find that is the way to go.
In fact, needs a meta-desktop module allowing adding users needs.
Plus, apt allows a fine managing of dependencies so it seems not being 
too much hard to do.

> ubuntu-doc-generic - contains non distro specific documentations like 
> gnome2-manual, diveintopython, and mozilla default start page.
> ubuntu-desktop-generic - only contains the components for the desktop

> ubuntu-live-generic - use a chosen language as default, provides 
> freedom to remove languages.
> Modularization of settings.
> Package creation of the following.
> gnome-panel-help-ubuntu - will use the ubuntu-doc files that links to 
> "System > Help" submenu.
> gnome-panel-help-generic - does not use the ubuntu-doc files but 
> contains link to ubuntu-doc-generic, and launchpad generic help 
> sources page.
> Gconf defaults.

> The proposal is to define the gconf settings in seperate packages,

> - gconf-settings-generic
> A user must be able to choose a settings in place of the other, and 
> remove the unused settings without dependency problems.
