+        The GIMP Toolkit input method modules
+        (<filename>gtk-immodules-cache</filename>) class
+        generates the proper post-install and post-remove (postinst/postrm)
+        scriptlets for packages that install GTK+ input method modules for
+        virtual keyboards.
+        These scriptlets call <filename>gtk-update-icon-cache</filename> to add
+        the input method modules to the 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.
