+// CSecurity - class on the client side for handling security handshaking.  A
+// derived class for a particular security type overrides the processMsg()
+// method.  processMsg() is called first when the security type has been
+// decided on, and will keep being called whenever there is data to read from
+// the server until either it returns false, indicating authentication/security
+// failure, or it returns with done set to true, to indicate success.
+//
+// Note that the first time processMsg() is called, there is no guarantee that
+// there is any data to read from the CConnection's InStream, but subsequent
+// calls guarantee there is at least one byte which can be read without
+// blocking.
+//
+// description is a string describing the level of encryption applied to the
+// session, or null if no encryption will be used.
