Package: debhelper Version: 5.0.35 Severity: wishlist Tags: patch The following patch will add functionality to debhelper to easily create a .postinst and .postrm to handle the GTK icon cache. It uses /usr/bin/gtk-update-icon-cache (of libgtk2.0-bin, if available) to manage an mmap()able file, which makes icon look up faster and shortens the amount of used memory for GTK processes by ~300k. XFCE and GNOME will benefit of this.
The implementation of GTK's icon cache wants to have a changed mtime in the directory above of the one where icons were added. As this doesn't happen automatically, using dh_iconcache makes this easier for package maintainers. Have a nice day, Daniel

+=head1 SYNOPSIS
+
+B<dh_iconcache> [S<I<debhelper options>>] [B<-p<package>>]
+
+=head1 DESCRIPTION
+
+dh_iconcache is a debhelper program that updates the GTK icon cache.
+This is necessary, if packages install icons into /usr/share/icons/B<package>.
+Currently this program does not handle installation of icons, though
+may do so at a later date. It takes care of adding maintainer script
+fragments to call F<gtk-update-icon-cache>.
