   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/
