r2010: * dh_icons: New program to update Freedesktop icon caches. Thanks

  to Josselin Mouette, Ross Burton, Jordi Mallach, and Loïc Minier.
  Closes: #329460
* Note that as a transitional measure, dh_icons will currently only update
  existing caches, and not create and new caches. Once everything is
  updating the icon caches, this will be changed. See #329460 for the full
  plan.

+=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
+

+Do not modify maintainer scripts.
