dh_gconf - generate GConf schema registration scripts

=head1 SYNOPSIS

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

=head1 DESCRIPTION

dh_gconf is a debhelper program that is responsible for registering
GConf schemas.

It automatically generates the postinst and prerm fragments needed
to register and unregister the schemas in usr/share/gconf/schemas, using
gconf-schemas.

If a file named debian/package.gconf-defaults exists, then it is
installed into usr/share/gconf/defaults/10_package in the package build
directory, with "package" replaced by the package name. Some postinst and
postrm fragments will be generated to launch update-gconf-defaults.

If a file named debian/package.gconf-mandatory exists, then it is
installed into usr/share/gconf/mandatory/10_package in the package build
directory, with "package" replaced by the package name, and similar
postinst and postrm fragments will be generated.

The gconf-schemas and update-gconf-defaults scripts are provided by the
gconf2 package. An appropriate dependency will be generated in
${misc:Depends}.

=head1 OPTIONS

=over 4

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

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