<h3>Checking PHP extensions</h3>
<p class="hint">The following modules/extensions are <em>required</em> to run RoundCube:</p>
<?php

<h3>Checking available databases</h3>
<p class="hint">Check which of the supported extensions are installed. At least one of them is required.</p>

<h3>Check for required 3rd party libs</h3>
<p class="hint">This also checks if the include path is set correctly.</p>
