+# Keymaps table
+#
+# This table creates an association between a keycode file and a kernel
+# driver. It can be used to automatically override a keycode definition.
+#
+#
+# Format:
+#       driver - name of the driver provided via uevent - use * for any driver
+#       table -  RC keymap table, provided via uevent - use * for any table
+#       file - file name. If directory is not specified, it is first looked up
+#               in /storage/.config/rc_keymaps, then /usr/lib/udev/rc_keymaps
+#
+# For example:
+#
+# driver        table           file
+#
+# gpio-rc-recv  rc-streamzap    streamzap
+# gpio-rc-recv  *               justboom
+# *             rc-rc6-mce      rc6_mce_new
+# *             *               hauppauge_new
