The great thing about standards is that there are so many to choose
from. The POSIX getopt() standard *does* require that options appear
before arguments:

        naming-schemes# uname
        NetBSD
        naming-schemes# ls /root -al
        ls: -al: No such file or directory
        /root:
        [Listing of files under /root]

but the gnu getopt implementation does not have that requirement:

        drug-lord% uname
        Linux
        drug-lord% ls /root -al
        total 64

Unless you set POSIXLY_CORRECT:

        drug-lord% setenv POSIXLY_CORRECT
        drug-lord% ls /root -al
        ls: -al: No such file or directory
