+00084    of `struct option' terminated by an element containing a name which is
+00085    zero.
+00086 
+00087    The field `has_arg' is:
+00088    no_argument          (or 0) if the option does not take an argument,
+00089    required_argument    (or 1) if the option requires an argument,
+00090    optional_argument    (or 2) if the option takes an optional argument.
+00091 
+00092    If the field `flag' is not NULL, it points to a variable that is set
+00093    to the value given in the field `val' when the option is found, but
+00094    left unchanged if the option is not found.
+00095 
+00096    To have a long-named option do something other than set an `int' to
+00097    a compiled-in constant, such as set a value from `optarg', set the
+00098    option's `flag' field to zero and its `val' field to a nonzero
+00099    value (the equivalent single-letter option character, if there is
+00100    one).  For long options that have a zero `flag' field, `getopt'
