/* Describe the long-named options requested by the application.
|

The LONG_OPTIONS argument to getopt_long or getopt_long_only is a vector
|
||||
of 'struct option' terminated by an element containing a name which is
|
||||
zero.
|
||||
|
||||
The field 'has_arg' is:
|
||||
no_argument (or 0) if the option does not take an argument,
|
||||
required_argument (or 1) if the option requires an argument,
|
||||
optional_argument (or 2) if the option takes an optional argument.
|
||||
|
||||
If the field 'flag' is not NULL, 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. */

The OPTS string is a list of characters which are recognized option

letters, optionally followed by colons, specifying that that letter

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
