# This file is a simple shell script wrapper for the IDL to
|
|
# Wireshark dissector code.
|
|
#
|
|
# ie: wireshark_be.py and wireshark_gen.py
|
|
#
|
|
# This file is used to generate "Wireshark" dissectors from IDL descriptions.
|
|
# The output language generated is "C". It will generate code to use the
|
|
# GIOP/IIOP get_CDR_XXX API.
|
|
#
|
|
# Please see packet-giop.h in Wireshark distro for API description.
