/* Unlike standard Unix `getopt', functions like `getopt_long'
49
let the user intersperse the options with the other arguments.

/* This version of `getopt' appears to the caller like standard Unix `getopt'
45
but it behaves differently for the user, since it allows the user
46
to intersperse the options with the other arguments.

As `getopt_long' works, it permutes the elements of ARGV so that,
52
49
when it is done, all the options precede everything else. Thus

55
52
Using `getopt' or setting the environment variable POSIXLY_CORRECT
56
53
disables permutation.
57
Then the application's behavior is completely standard.

GNU application programs can use a third alternative mode in which
60
57
they can distinguish the relative order of options and other arguments. */
