title: Notating Multiple Modules in the Same Package.json File
body: <p>I am trying to package up some modules that I have been working on. I have five modules, split in to five files. Four of them are the actual outward-facing modules that I want the user to be able to install. The other one is a support module that they all need to function correctly. They are all stored in the same directory. I want to be able to specify each as a separate module in the same directory. But as far as I can tell, one can only define a single module in <code>package.json</code>.</p>
  
  <p>Is there a way to specify multiple modules? If not, that means this must be a bad practice. How should I structure my module's exports to move it in to one main module?</p>
