+ * protobuf packet correctly. The information includes:
+ *   - The names of MESSAGE, ENUM, FIELD, ENUM_VALUE;
+ *   - The data type of FIELD which assuring the value of protobuf field of packet can be dissected correctly.
+ *
+ * At present, we use C Protocol Buffers Language Parser which generated by protobuf_lang_parser.lemon and protobuf_lang_scanner.l.
+ * Because wireshark is mainly implemented in plain ANSI C but the offical protobuf library is implemented in C++ language.
+ *
+ * One day, if C++ library is allowd, we can create a protobuf-helper.cpp file, that invoking offical protobuf C++ library directly,
+ * to replace protobuf-helper.c. The packet-protobuf.c can keep unchanged.
