<description summary="Remote lua interface for Mezzaluna">
This protocol allows clients to receive lua errors from mez and execute lua
on a running mez server with the lua mez api.
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.

The compositor sends this event to inform the client that it has a new
log entry for the client.
The text contains the lua log information the server generates when
executing lua code. The server does not hold logs from before the client
connect, and therefore you will only recieve log information from the
point that you start listening for them and on.
