title: Require tree in asset pipeline
body: <p>I have a folder in my asset pipeline called typefaces. It works without any additions to <code>application.rb</code>. </p>
  
  <p>In the directory I have different typeface types, like .eof, .ttf, etc in folders, like this</p>
  
  <pre><code>Assets
      Typefaces
          Eof
             ...files
          Ttf
             ...files
  </code></pre>
  
  <p>Unless the typefaces are in Assets/typefaces they don't become part of asset pipeline. Asset pipeline doesn't go into the subdirectories. </p>
  
  <p>How would I have asset pipeline look beyond assets/typefaces into assets/typefaces/eof, assets/typefaces/ttf etc?</p>
