+The BaseX Node client is asynchronous.  Most functions take an option
+callback function as last argument. The callback function will be 
+called when the results are available with two arguments.
+The first will contain any error infomation or null if there is no error
+the second will hold the result.
+The utility function `print` shows the syntax:
+ 
+		function print(err, reply) {
+			if (err) {
+				console.log("Error: " + err);
+			} else {
+				console.dir(reply);
+			}
+		}; 
+
+## Session
+var client=Session(host, port, username, password)
+	hostname (default="localhost")
+	port (default=1984)
+	username (default="admin")
+	password (default= "admin")
+
+ 
+## execute
+
+## create
+## add
+## replace
+## store
+## info
+## close
+
+## query
+
+## Debugging
+The basex module variable `debug_mode` can be set to true to 
+print diagnostic info to the console.
