=head1 NAME
dh_icons - Update caches of Freedesktop icons
=cut

=head1 SYNOPSIS
B<dh_icons> [S<I<debhelper options>>] [B<-n>]
=head1 DESCRIPTION
B<dh_icons> is a debhelper program that updates caches of Freedesktop icons
when needed, using the B<update-icon-caches> program provided by GTK+2.12.
Currently this program does not handle installation of the files, though it
may do so at a later date, so should be run after icons are installed in
the package build directories.
It takes care of adding maintainer script fragments to call
B<update-icon-caches> for icon directories. (This is not done for gnome and
hicolor icons, as those are handled by triggers.)
These commands are inserted into the maintainer scripts by L<dh_installdeb(1)>.
=head1 OPTIONS
=over 4
=item B<-n>, B<--noscripts>
Do not modify maintainer scripts.
