There isn't one: for some weird reason, GNU Grep maintainers decided
to produce only one executable program, named `grep' (`grep.exe' on
DOS and Windows), and have `egrep' and `fgrep' as Unix shell scripts.
Let the fleas of a thousand camels infest the armpits of those who
change old-standing Unix traditions of having 3 programs in the Grep
package!
