+
+=head1 SYNOPSIS
+
+B<dh_icons> [S<I<debhelper options>>] [B<-n>]
+
+=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>.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-n>, B<--noscripts>
+
+Do not modify maintainer scripts.
