/* Describe the long-named options requested by the application.
   _GETOPT_LONG_OPTIONS is a vector of `struct option' terminated by an
   element containing a name which is zero.

   The field `has_arg' is:
   0 if the option does not take an argument,
   1 if the option requires an argument,
   2 if the option takes an optional argument.

   If the field `flag' is nonzero, it points to a variable that is set
   to the value given in the field `val' when the option is found, but
   left unchanged if the option is not found.

   To have a long-named option do something other than set an `int' to
   a compiled-in constant, such as set a value from `optarg', set the
   option's `flag' field to zero and its `val' field to a nonzero
   value (the equivalent single-letter option character, if there is
   one).  For long options that have a zero `flag' field, `getopt'
   returns the contents of the `val' field.  */
