# Description:
#   
#   Omniidl Back-end which parses an IDL data structure provided by the frontend
#   and generates packet-idl-xxx.[ch] for compiling as a dissector in 
#   Wireshark IP protocol anlayser.
#
#  
#
#
# Strategy. 
#
# Crawl all the way down all branches until I hit  "Operation", "Enum", "Attribute",
# "Struct" and "Union" nodes.  Then store these nodes in lists.
#
# Pass these lists (via an object ref) to the src code
# generator (wireshark_gen) class and let it do the hard work ! 
#
#
# Dont forget structs can contain embedded structs etc .. so dont forget
# to peek inside and check :-)
