No ELF specific loader has been written so I would go ahead and write one in python and check it into $(trunk)/examples/python as loadelf.py. I am not sure if you can add a python command as a child of an existing command, but you can call it "load-elf". There are a few open source ELF parsers in python, and I have one if you need it so that you don't have to write one from scratch.

Thanks for your comments. I was thinking of adding a normal command in C++ instead of python. Do you think that is not the right way to go about it?

Thanks,
Abid
