175    The LONG_OPTIONS argument to getopt_long or getopt_long_only is a vector
176    of `struct option' terminated by an element containing a name which is
177    zero.
178 
179    The field `has_arg' is:
180    no_argument          (or 0) if the option does not take an argument,

182    optional_argument    (or 2) if the option takes an optional argument.

185    to the value given in the field `val' when the option is found, but
186    left unchanged if the option is not found.
187 
188    To have a long-named option do something other than set an `int' to
189    a compiled-in constant, such as set a value from `optarg', set the
190    option's `flag' field to zero and its `val' field to a nonzero
191    value (the equivalent single-letter option character, if there is
192    one).  For long options that have a zero `flag' field, `getopt'
193    returns the contents of the `val' field.  */

222    missing arguments, `optopt' is set to the option letter, and '?' is
223    returned.
224 
225    The OPTS string is a list of characters which are recognized option
226    letters, optionally followed by colons, specifying that that letter
227    takes an argument, to be placed in `optarg'.
228 
229    If a letter in OPTS is followed by two colons, its argument is
230    optional.  This behavior is specific to the GNU `getopt'.
231

233    scanning, explicitly telling `getopt' that there are no more
234    options.
235 
236    If OPTS begins with `-', then non-option arguments are treated as
237    arguments to the option '\1'.  This behavior is specific to the GNU
238    `getopt'.  If OPTS begins with `+', or POSIXLY_CORRECT is set in
239    the environment, then do not permute arguments.  */
