PSR4 auto load without composer
<p>I have one package in a project which is autoloaded using composer and composer.json entry is as follows : </p>

<pre><code> "autoload": {
      "psr-4": {
        "CompanyName\\PackageName\\": "packages/package-folder/src/"
    }
  }
</code></pre>

<p>Now I am copying this over to another project which is not using composer. How can I autoload this same package there ?</p>
