+// Description:
+// MbufGobbler selector. Used by the Tier Manager to select the access point below
+//  (management plane)
+//
+//
+//  This is a 3-plane comms layer implementation example, which has been customised to be a test layer which gobbles and releases ESOCK MBUFs.
+//  The MBuf gobbling functionality can be disabled by undefining the macro SYMBIAN_COMMSFW_MBUF_GOBBLER which is specified in mbufgobblerproviders.mmp.
+//  When SYMBIAN_COMMSFW_MBUF_GOBBLER is undefined, the source code specified by mbufgobblerproviders.mmp becomes a pass through layer i.e. it passes the data
+//  through to the layer above or below without altering it. This makes it useful as a starting point for implementing your own layers / providers;
+//  useful documentation on how to customise your own passthrough layer can be found in ..\docs\MbufGobblerLayer.doc
+//
