Question on shared-mime-info adoption

[Luca Dionisi]

Hi all,

How much does Gnome adhere to the shared-mime-info spec?
In particular, is this spec used in Nautilus in order to find the
icon to use for a particular file?

I'm building my own system with the Linux From Scratch book,
and I'm asking this beacuse of the presence of a package in
gnome (GNOME MIME Data-2.4.2) that installs 2 dirs in
/usr/share:
 application-registry
            contains the application mime database.
 mime-info
            contains the mime description database.

Any information will be appreciated

Thanks a lot.

Luca
