<h1>Module HowTo - Defining required extensions<br>
</h1>
<div style="text-align: left;"><br>
Your account module might require special PHP extensions. LAM can check
this for you and display an error message at the login page.<br>
<br>
</div>
<div style="text-align: left;">You will need to implement the function <span
style="font-weight: bold;">getRequiredExtensions()</span> or use <span

<br>
<span style="font-weight: bold; text-decoration: underline;">Example:</span><br
style="font-weight: bold; text-decoration: underline;">
<br>
The <span style="font-style: italic;">posixAccount</span> module needs
to generate password hashes. Therefore it needs the MHash extension.<br>
