+Detects the version of an Oracle Virtual Server Agent by fingerprinting
+responses to an HTTP GET request and an XML-RPC method call.
+
+Version 2.2 of Virtual Server Agent returns a distinctive string in response to an
+HTTP GET request. However versions 3.0 and 3.0.1 return a generic response that
+looks like any other BaseHTTP/SimpleXMLRPCServer. Versions 2.2 and 3.0 return a
+distinctive error message in response to a <code>system.listMethods</code>
+XML-RPC call, which however does not distinguish the two versions. Version 3.0.1
+returns a response to <code>system.listMethods</code> that is different from
+that of both version 2.2 and 3.0. Therefore we use this strategy: (1.) Send a
+GET request. If the version 2.2 string is returned, return "2.2". (2.) Send a
+<code>system.listMethods</code> method call. If an error is
+returned, return "3.0" or "3.0.1", depending on the specific format of the
+error.
