<interface name="zriver_control_v1" version="1">
<description summary="run compositor commands">
This interface allows clients to run compositor commands and receive a
success/failure response with output or a failure message respectively.
Each command is built up in a series of add_argument requests and
executed with a run_command request. The first argument is the command
to be run.
A complete list of commands should be made available in the man page of
the compositor.
</description>
<request name="destroy" type="destructor">
<description summary="destroy the river_control object">
This request indicates that the client will not use the
river_control object any more. Objects that have been created
through this instance are not affected.

Arguments are stored by the server in the order they were sent until
the run_command request is made.
