synopsis: A powerful and easy-to-use command-line option parser.
description:
    The @options@ package lets library and application developers easily work
    with command-line options.
    .
    The following example is a full program that can accept two options,
    @--message@ and @--quiet@:
    .
    @
    import Control.Applicative
    import Options
    .
    data MainOptions = MainOptions
    &#x20;   &#x7b; optMessage :: String
    &#x20;   , optQuiet :: Bool
    &#x20;   &#x7d;
    .
    instance 'Options' MainOptions where
    &#x20;   defineOptions = pure MainOptions
    &#x20;       \<*\> simpleOption \"message\" \"Hello world!\"
    &#x20;           \"A message to show the user.\"
    &#x20;       \<*\> simpleOption \"quiet\" False
    &#x20;           \"Whether to be quiet.\"
    .
    main :: IO ()
    main = runCommand $ \\opts args -> do
    &#x20;   if optQuiet opts
    &#x20;       then return ()
    &#x20;       else putStrLn (optMessage opts)
    @
    .
    >$ ./hello
    >Hello world!
    >$ ./hello --message='ciao mondo'
    >ciao mondo
    >$ ./hello --quiet
    >$
    .
    In addition, this library will automatically create documentation options
    such as @--help@ and @--help-all@:
    .
    >$ ./hello --help
    >Help Options:
    >  -h, --help
    >    Show option summary.
    >  --help-all
    >    Show all help options.
    >
    >Application Options:
    >  --message :: text
    >    A message to show the user.
    >    default: "Hello world!"
    >  --quiet :: bool
    >    Whether to be quiet.
    >    default: false
