title: PHP auto_prepend_file alternative in NodeJS
body: <p>In my NodeJS environment, I want to include a file that will contain some personal helper functions. </p>
  
  <p>Basically I want the same behavior as PHP <a href="http://php.net/manual/en/ini.core.php#ini.auto-prepend-file" rel="nofollow">auto_prepend_file</a></p>
  
  <p>It should be included automatically both in projects as well as NodeJS CLI. Ideally it shouldn't require <code>require</code> statement. It should just create some global variables for functions that are available everywhere.</p>
