B<dh_installgsettings> [S<I<debhelper options>>] [B<--priority=<number>>]

B<dh_installgsettings> is a debhelper program that is responsible for installing
GSettings override files and generating appropriate dependencies on the
GSettings backend.

The dependency on the backend will be generated in B<${misc:Depends}>.

=item debian/I<package>.gsettings-override

Installed into usr/share/glib-2.0/schemas/10_I<package>.gschema.override in

=head1 OPTIONS

=over 4

=item B<--priority> I<priority>

Use I<priority> (which should be a 2-digit number) as the override
priority instead of 10. Higher values than ten can be used by 
derived distributions (20), blend distributions (50), or site-specific
packages (90).
