title: Wordpress Plugin Install Using Composer and Custom Repo Path
body: <p>I'm building a wordpress site using Roots/Bedrock with Composer.  Everything has been working great so far, but I'm having a problem installing plugins from Github where the core plugin files are in a subdirectory.</p>
  
  <p>Here's an example:</p>
  
  <p>Plugin package entry</p>
  
  <pre><code>  {
    "type": "package",
    "package": {
      "name": "katzwebservices/Gravity-Forms-Salesforce",
      "type": "wordpress-plugin",
      "version": "3.0.6.1",
      "source": {
        "type": "git",
        "url": "git@github.com:katzwebservices/Gravity-Forms-Salesforce.git",
        "reference": "origin/master",
        "package-path": "trunk/"
        },
      "require" : { "composer/installers": "v1.0.12" },
      }
  </code></pre>
  
  <p>This installs the "Trunk" directory into the "Gravity-Forms-Salesforce" directory.</p>
  
  <p>If I move the files in "Trunk" to the "Gravity-Forms-Salesforce" directory, the plugin is recognized.</p>
  
  <p>Is there a way to install only the files in "Trunk" directly into "Gravity-Forms-Salesforce" directory through Composer?  The "package-path" option doesn't seem to do anything.</p>
  
  <p>Thanks!</p>
