+ * Control power management modes of outputs
+ *
+ * @section page_desc_wlr_output_power_management_unstable_v1 Description
+ *
+ * This protocol allows clients to control power management modes
+ * of outputs that are currently part of the compositor space. The
+ * intent is to allow special clients like desktop shells to power
+ * down outputs when the system is idle.
+ *
+ * To modify outputs not currently part of the compositor space see
+ * wlr-output-management.
+ *
+ * Warning! The protocol described in this file is experimental and
+ * backward incompatible changes may be made. Backward compatible changes
+ * may be added together with the corresponding interface version bump.
+ * Backward incompatible changes are done by bumping the version number in
+ * the protocol and interface names and resetting the interface version.
+ * Once the protocol is to be declared stable, the 'z' prefix and the
+ * version number in the protocol and interface names are removed and the
+ * interface version number is reset.
