       idl2eth - CORBA IDL to Ethereal Plugin Generator

       idl2eth filename

       idl2eth is a program that takes a user specified CORBA IDL file and generates "C" source
       code for an Ethereal "plugin".

       This resulting file can be compiled as an Ethereal plugin, and used to monitor GIOP/IIOP
       traffic that is using this IDL.

       idl2eth is actually a shell script wrapper for two Python programs.

       These programs are:

	   ethereal_be.py  - Contains the main IDL Visitor Class

	   ethereal_gen.py - Contains the Source Code Generator Class

	   idl2eth supports heuristic dissection of GIOP/IIOP traffic, and some experimental code
	   for explicit dissection, based on Object Key <-> Repository Id mapping.  However, code
	   for heuristic based plugins is generated by default, and users should consider this
	   the preferred method unless you have some namespace collisions.

       Currently there are no options. idl2eth can be invoked as follows.

       1.  To write the C code to stdout.

	   idl2eth  <your_file.idl>

	   eg: idl2eth echo.idl

       2. To write to a file, just redirect the output.

	   idl2eth echo.idl > packet-test.c

       idl2eth will look for ethereal_be.py and ethereal_gen.py in $PYTHONPATH/site-packages/ and
       if not found, will try the current directory ./

       The -p option passed to omniidl (inside idl2eth) indicates where ethereal_be.py and ethe-
       real_gen.py will be searched.  This may need tweaking if you place these files somewhere

       If it complains about being unable to find some modules (eg tempfile.py), you may want to
       check if PYTHONPATH is set correctly.

       eg:  PYTHONPATH=/usr/lib/python1.5/


       idl2eth (including ethereal_be.py and ethereal_gen.py) are part of the Ethereal distribu-
       tion.  The latest version of Ethereal can be found at http://www.ethereal.com.

       idl2eth uses omniidl, and IDL parser, and can be found at

       Some of the more important things to do are:

       o Improve Explicit dissection code.
       o Improve command line options.
       o Improve decode algorithm when we have operation name collision.
