 * @page page_wlr_output_power_management_unstable_v1 The wlr_output_power_management_unstable_v1 protocol
 * 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.
