This console front-controller file is the gateway to your application
through the command line.  It is responsible for intercepting requests, and
handing them off to the `Dispatcher` for processing.

Determine if we're in an application context by moving up the directory tree
looking for a `config` directory with a `bootstrap.php` file in it.  If no
application context is found, just boot up the core framework.

{{{

$params = getopt("", array("app::"));
$working = $params ? array_pop($params) : getcwd();
$app = null;

}}}

If we're not running inside an application (i.e. a self-bootstrapping library), bootstrap the
core automatically with the default settings.

{{{

$bootstrap = function() use ($working) {
	define('LITHIUM_LIBRARY_PATH', dirname(dirname(__DIR__)));
	define('LITHIUM_APP_PATH', $working);

	if (!include LITHIUM_LIBRARY_PATH . '/lithium/core/Libraries.php') {
		$message  = "Lithium core could not be found.  Check the value of LITHIUM_LIBRARY_PATH in ";
		$message .= __FILE__ . ".  It should point to the directory containing your ";
		$message .= "/libraries directory.";
		throw new ErrorException($message);
	}

	lithium\core\Libraries::add('lithium');
	lithium\core\Libraries::add(basename($working), array(
		'default' => true,
		'path' => $working,
		'resources' => sys_get_temp_dir()
	));
};

}}}

The following will dispatch the request and exit with the status code as
provided by the `Response` object returned from `run()`.

The following will instantiate a new `Request` object and pass it off to the
`Dispatcher` class.  By default, the `Request` will automatically aggregate
all the server / environment settings, and request content (i.e. options and
arguments passed to the command) information.

The `Request` is then used by the `Dispatcher` (in conjunction with the
`Router`) to determine the correct command to dispatch to. The response
information is then encapsulated in a `Response` object, which is returned
from the command to the `Dispatcher`.

The `Response` object will contain information about the status code which
is used as the exit code when ending the execution of this script and
returned to the callee.

{{{

$run = function() {
	return lithium\console\Dispatcher::run(new lithium\console\Request())->status;
};

}}}

Look to see if there's a bootstrap file. If there is, this is either a Lithium application or
plugin.

{{{

if (file_exists("{$working}/config/bootstrap.php")) {
	$app = $working;
} elseif (file_exists("{$working}/app/config/bootstrap.php")) {
	$app = "{$working}/app";
}

}}}

Attempt to bootstrap the application and execute the request. On failure, use the default
bootstrap.

{{{

if ($app) {
	foreach (array("bootstrap.php", "bootstrap/libraries.php") as $file) {
		if (!file_exists($path = "{$app}/config/{$file}")) {
			continue;
		}
		if (preg_match("/^define\([\"']LITHIUM_LIBRARY_PATH[\"']/m", file_get_contents($path))) {
			include "{$app}/config/bootstrap.php";
			exit($run());
		}
	}
}

}}}

We're not running inside a Lithium application. Use the default bootstrap and execute the
request.

{{{

$bootstrap();
$app ? include "{$app}/config/bootstrap.php" : null;
exit($run());

}}}
