title: In IntelliJ IDEA, is the project itself also a module?
body: <p>IntelliJ IDEA Community Edition 14</p>
  
  <p>When I right-click the Project Name (effectively the Workspace in other IDE's), in the menu are a few references to it being a module ("<code>remove module ___</code>", "<code>make module ___</code>", "<code>compile module ___</code>", where <code>___</code> is the project name.</p>
  
  <p><strong>QUESTION 1:</strong> So is an IDEA project conceptually <em>also</em> a module, or have I configured this incorrectly?</p>
  
  <p>To be clear, I've also noticed that the folder hierarchy for the project (named "WorkspaceI") looks like this (trailing \ indicates a folder):</p>
  
  <pre><code>F:\DEVEL\WorkspaceI\.idea\
  F:\DEVEL\WorkspaceI\ALife\
  F:\DEVEL\WorkspaceI\out\
  F:\DEVEL\WorkspaceI\src\
  F:\DEVEL\WorkspaceI\TGM_Common\
  F:\DEVEL\WorkspaceI\WorkspaceI.iml
  </code></pre>
  
  <p><code>ALife</code> and <code>TGM_Common</code> are modules.  I understand how <code>out\</code> was configured to hold all the module's class files.</p>
  
  <p><strong>QUESTION 2:</strong> But what is the <code>src</code> folder for?  Some sort of source hierarchy common to all modules?  That's what module dependencies are for.</p>
