How i would like to use Composer Install Commands with CloudControl

cloudcontrol_composer_install.php

<?php
namespace APPNAME\Composer;

use Composer\Script\Event;

class Install
{


    private static $appName = 'APPNAME';
    private static $depoymentName = 'DEPLOYMENTNAME';
    private static $newrelicApiKey = 'ENTER YOUR NEW RELIC API KEY';
    private static $cloudcontrolUser = 'ENTER YOUR cloudcontrol Username';


    public static function preInstall(Event $event) {
        // provides access to the current ComposerIOConsoleIO
        // stream for terminal input/output
        $io = $event->getIO();
        $io->write("Installing ".self::$appname);
        $io->write("Deployment ".self::$depoymentName);

    }
    public static function preUpdate(Event $event) {
        // provides access to the current ComposerIOConsoleIO
        // stream for terminal input/output
        $io = $event->getIO();
        $io->write("Updating ".self::$appname);
        $io->write("Deployment ".self::$depoymentName);
    }
    public static function postInstall(Event $event) {
        // provides access to the current Composer instance
        $composer = $event->getComposer();
        // run any post install tasks here

        $io = $event->getIO();

        if ( $_SERVER['PAAS_VENDOR'] == 'cloudControl' ) {
            $ch = curl_init();


            if ($event->isDevMode()){
                $deployment = "dev";
            }else {
                $deployment = "default";
            }

            $description = "Automatic deployment info";

            $data ="deployment[app_name]=".self::$appName.'/'.self::$depoymentName.
                "&deployment[description]=".$description.
                "&deployment[user]=".self::$cloudcontrolUser;

            curl_setopt($ch, CURLOPT_URL, 'https://rpm.newrelic.com/deployments.xml');
            curl_setopt($ch,CURLOPT_HTTPHEADER,array('x-api-key:'.self::$newrelicApiKey));
            curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
            curl_setopt($ch, CURLOPT_POST ,1);
            curl_exec($ch);
            curl_close($ch);

        }


        $io->write("Installed ".self::$appName);
    }

    public static function postPackageInstall(Event $event) {
        $installedPackage = $event->getComposer()->getPackage();
        // any tasks to run after the package is installed?
    }
}

And the sample composer.json can be found here
