9#  This file is a simple shell script wrapper for the IDL to
10#  Wireshark dissector code.
11#
12#  ie: wireshark_be.py and wireshark_gen.py
13#
14#  This file is used to generate "Wireshark" dissectors from IDL descriptions.
15#  The output language generated is "C". It will generate code to use the
16#  GIOP/IIOP get_CDR_XXX API.
17#
18#  Please see packet-giop.h in Wireshark distro for API description.
19#  Wireshark is available at https://www.wireshark.org/
