\Cli\Helpers\Script and \Cli\Helpers\DocumentedScript

Utility class to write scripts as objects.

#!/usr/bin/env php
require_once dirname(__FILE__) . '/path/to/vendor/autoload.php';

use Cli\Helpers\DocumentedScript;
use Cli\Helpers\Parameter;

$script = new DocumentedScript();
    ->setDescription('Test script for Cli\Helpers\DocumentedScript')
    ->setCopyright('Copyright (c) Alexandre Mercier 2014')
    ->addParameter(new Parameter('H', 'host'    , '')              , 'Host.')
    ->addParameter(new Parameter('u', 'username', Parameter::VALUE_REQUIRED), 'User name.')
    ->addParameter(new Parameter('p', 'password', Parameter::VALUE_REQUIRED), 'Password.')
    ->addParameter(new Parameter('v', 'verbose' , Parameter::VALUE_NO_VALUE), 'Enable verbosity.')
    ->setProgram(function ($options, $arguments) {

While Script doesn't have any pre-configured switch, DocumentedScript has --h, --help and -V, --version. This provides an automaic handling of this two switches.
