-/* Get definitions and prototypes for functions to process the
-   arguments in ARGV (ARGC of them, minus the program name) for
-   options given in OPTS.
-
-   Return the option character from OPTS just read.  Return -1 when
-   there are no more options.  For unrecognized options, or options
-   missing arguments, 'optopt' is set to the option letter, and '?' is
-   returned.
-
-   The OPTS string is a list of characters which are recognized option
-   letters, optionally followed by colons, specifying that that letter
-   takes an argument, to be placed in 'optarg'.
-
-   If a letter in OPTS is followed by two colons, its argument is
-   optional.  This behavior is specific to the GNU 'getopt'.
-
-   The argument '--' causes premature termination of argument
-   scanning, explicitly telling 'getopt' that there are no more
-   options.
-
-   If OPTS begins with '-', then non-option arguments are treated as
-   arguments to the option '\1'.  This behavior is specific to the GNU
-   'getopt'.  If OPTS begins with '+', or POSIXLY_CORRECT is set in
-   the environment, then do not permute arguments.  */
