Huh????? We *have* /usr/bin/{ar,nm,aout,ld,as,size,strings,strip,...},
these are links to objformat, which is a redirector to the /usr/lib/
{aout,elf} backend.
So, "/usr/bin/nm" gets the system default (either /usr/libexec/aout/nm or
/usr/libexec/elf/nm depending on the user's or system preference), while "/
usr/bin/nm -elf" forces execution of /usr/libexec/elf/nm, and the same for
-aout.
