=head1 SYNOPSIS

B<dh_icons> [S<I<debhelper options>>] [B<-p<package>>]

=head1 DESCRIPTION

dh_icons is a debhelper program that updates Freedesktop icon caches
when needed, using the gtk-update-icon-cache program provided by GTK+2.0.
Currently this program does not handle installation of the files, though it
may do so at a later date. It takes care of adding maintainer script
fragments to call F<gtk-update-icon-cache>.
