        $limit = $argv[2]??50;
    }else{
        $req = unserialize(base64_decode($argv[1]));
        $target = $req["target"];
        $limit = $req["max"]??50;
    }
}
$craw = new EmailCrawl($target, $limit);
$response = $craw->craw()->getResponse();

$crawOptions = array(

    'max' => 50,
);
$crawRequest = base64_encode(serialize($crawOptions));
$crawScript =  __DIR__ . "/craw.php";
$crawLogs =  __DIR__ . "/craw_logs.log";
shell_exec(PHP_SHELL_EXECUTION_PATH . " " . $crawScript . " " . $crawRequest ." 'alert' >> " . $crawLogs . " 2>&1");
