diff of binaries

[john.p.letourneau]

Hi, I was wondering if there was something floating out there in source
land to essentially do a diff -e on an executable file...aka binary.
Sorry I can't say why I need to do such a thing, but it sure helps in
versioning things. The programs are in excess of 1 meg so I need something
that takes less than a year to run! 8-) Any information is appreciated.
