Well you can if you follow the same steps that the script uses to create
a flat file.  You just can't run elf2flt on an elf file and expect it to
work,  it is not that simple.  You need to link the elf file in the
correct way and call elf2flt with the correct parameters based on the
kind of elf file and flat file you are producing.

The script will show you how to do this and I think there is some doc in
the elf2flt source that gives a simplified description.

What sort of dev environment are you using that makes using the script
so hard ?
