+Thrift Protocol Structure

+--------------------------------------------------------------------
+
+This document describes the structure of the Thrift protocol
+without specifying the encoding. Thus, the order of elements
+could in some cases be rearranged depending upon the TProtocol
+implementation, but this document specifies the minimum required
+structure. There are some "dumb" terminals like STRING and INT
+that take the place of an actual encoding specification.
+
+They key point to notice is that ALL messages are just one wrapped
+<struct>. Depending upon the message type, the <struct> can be
+interpreted as the argument list to a function, the return value
+of a function, or an exception.
