+	------------------------------------------------
+	Description of the jsonEventLoop and JSON schema
+	------------------------------------------------
+
+Purpose: JSON-based asynchronous API for signal-cli.
+
+This mode is not intended to be used directly from the command line, but to 
+provide an easy use API for other scripting languages.
+
+signal-cli listens for JSON requests on stdin. Each JSON request must be
+a single valid JSON object (enclosed in {}), followed by LF. The JSON text
+itself hence must not contain linefeeds (only escaped as \n and no pretty
+printing enabled).
+
+When incoming messages are received from the signal back-end, they are
+in turned JSON encoded and sent out on stdout.
+
+Any error messages or debug information is sent out on stderr as expected.
+
+Start signal-cli with the jsonEventLoop command to start this mode of operation.
+
+
+JSON Schema Version 2 
+=====================
+
+
+JSON Requests are read line by line from STDIN in "jsonEventLoop" mode and the Reponses are
+sent to STDOUT.
+
+Generic Request attributes valid for ALL requests
+{
+	"reqType": "<request-type>",				// MANDATORY: Name of request type
+	"reqID": <integer or string>				// Optional: reqID that will be present in the 
+												// response message for async callers to use as transaction id
+												// (note: for brevity omitted in the examples below)
+}
+Generic Response attributes valid for ALL responses
+{
+	"respType": "<response-type>",				// Name of response type
+	"reqID": <object>,							// Request Identifier as present in the request object
+	"statusCode": <int>,						// Status of the response. 0=OK, >0 = Error code (see Status code list)
+	"errorMessage": <string>					// Text describing error state, only present if statusCode > 0
+}
+
+
+When the jsonEventLoop command is started, it begins with emitting an metadata response
+containing some vital information for the "client" application.
+
+Metadata Response (automatically issued on startup)
+{
+	"respType": "metadata",
+	"apiVer": 2,								// Version of the API signal-cli uses

+												// signal-cli when downloaded from the server
+}
