"""Send a server-generated SocketIO message.
This function sends a simple SocketIO message to one or more connected
clients. The message can be a string or a JSON blob. This is a simpler
version of ``emit()``, which should be preferred. This function can be
used outside of a SocketIO event context, so it is appropriate to use
when the server is the originator of an event.
:param message: The message to send, either a string or a JSON blob.
:param json: ``True`` if ``message`` is a JSON blob, ``False``
otherwise.
:param namespace: The namespace under which the message is to be sent.
Defaults to the global namespace.
:param room: Send the message only to the users in the given room. If
this parameter is not included, the message is sent to
all connected users.
:param skip_sid: The session id of a client to ignore when broadcasting
or addressing a room. This is typically set to the
originator of the message, so that everyone except
that client receive the message.
:param callback: If given, this function will be called to acknowledge
that the client has received the message. The
arguments that will be passed to the function are
those provided by the client. Callback functions can
only be used when addressing an individual client.
