DESCRIPTION
The explain_execlp_or_die function is used to call the execlp(3) system call. On failure an explanation will be printed to stderr, obtained
from the explain_execlp(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_execlp_on_error function is used to call the execlp(3) system call. On failure an explanation will be printed to stderr,
obtained from the explain_execlp(3) function, but still returns to the caller.
RETURN VALUE
The explain_execlp_or_die function only returns on success, see execlp(3) for more information. On failure, prints an explanation and
exits, it does not return.
The explain_execlp_on_error function always returns the value return by the wrapped execlp(3) system call.
