   * This is a PHP command-line script to auto-grab the Metasploit's 14-DAYs pro trial key.
   * 
   * Really tired to submit the trial request to Metasploit manually to get the pro key every weeks just because of its unfriendly price ?
   * You have a new choice today !
   * Just run this script and wait a minute, it will generate a new pro trial key for you.
   * It's using Fake Name Generator and Fake Mail Generator to fetch the contact information to register, all are fake and disposable.
   * All the register processes are in automation, so enjoy it now !
