-        The GNOME (<filename>gtk-icon-cache</filename>) class
+        The GIMP Toolkit icon cache (<filename>gtk-icon-cache</filename>) class
+        Generates the proper post-install and post-remove (postinst/postrm)
+        scriptlets for packages that use GTK+ and install icons.
+        These scriptlets call <filename>gtk-update-icon-cache</filename> to add
+        the fonts to GTK+'s icon cache.
+        Since the cache files are architecture-specific,
+        <filename>gtk-update-icon-cache</filename> is run using QEMU if the
+        postinst scriptlets need to be run on the build host during image
+        creation.
