+D-BUS Configuration API v0.1
+----------------------------
+
+The X server will register the bus name org.x.config.displayN, and the 
+object /org/x/config/N, where N is the display number.
+
+Currently only hotplugging of input devices is supported.
+
+org.x.config.input:
+    org.x.config.input.add:
+        Takes an argument of key/value option pairs in arrays, e.g.:
+         [ss][ss][ss][ss]
+        is the signature for four options.  These options will be passed
+        to the input driver as with any others.
+        Option names beginning with _ are not allowed; they are reserved
+        for internal use.
+
+        Returns one int32, which is an X Status, as defined in X.h.  If
+        everything is successful, Success will be returned.  BadMatch will
+        be returned if the options given do not match any device.  BadValue
+        is returned for a malformed message.
+
+        Notably, BadAlloc is never returned: the server internally signals
+        to D-BUS that the attempt failed for lack of memory.
+
+        The return does not notify the client of which devices were created
+        or modified as a result of this request: clients are encouraged to
+        listen for the XInput DevicePresenceNotify event to monitor changes
+        in the device list.
+
+    org.x.config.input.remove:
+        Takes one int32 argument, which is the device ID to remove, i.e.:
+         i
+        is the signature.
+        Same return values as org.x.config.input.add.
