title: PSR-2. When to capitalize directories?
body: <p>As I understood according to PSR-2 standard we should capitalize directory names which contain classes. But how to do if the directory also contains some other files, for example styles and scripts?</p>
  
  <p>Say I have a plugin directory, each plugin can contain templates and other stuff:</p>
  
  <pre><code>plugins
    PluginName // lowercase?
      PluginName.php // Contains base class "PluginName"
      templates
        home.tpl
      css
        css.css
      js
        js.js
    PluginName2
      ....
  </code></pre>
  
  <p>Is this structure correct?</p>
