+This file includes all functions needed to manage configuration
+profiles. It includes classes for the profiles itself and the master
+configuration (default profile, master password, etc.).<br>
+<br>
+There are also two global functions for general use: <span
+ style="font-style: italic;">setlanguage</span> and <span
+ style="font-style: italic;">metarefresh</span><br>
+<br>
+<h2>Meta refresh</h2>
+The global function <span
+ style="font-weight: bold; font-style: italic;">metaRefresh()</span>
+takes an URL as argument and prints all HTML code needed for a meta
+refresh to this URL.<br>
+<br>
+<h2>Language</h2>
+LAM uses <span style="font-style: italic;">gettext</span> to translate
+the HTML pages to the different languages. Therefore some preferences
+need to be set on every page load. This is done by <span
+ style="font-style: italic; font-weight: bold;">setlanguage()</span>.<br>
+The function should be called directly after starting the session.<br>
+<br>
+The list of possible languages is stored in <span
+ style="font-style: italic;">config/language</span>. It includes the
+locale name, the character encoding an the language name.<br>
+All languages use UTF-8 as encoding because LDAP also stores values in
+this format.<br>
+<br>
+<h2>Configuration profiles</h2>
+Each configuration profile is saved in a single file in <span
+ style="font-weight: bold;">config/</span>.<br>
+<br>
+There are two types of configuration options:<br>
+<ul>
+  <li>Static options (LDAP server settings, etc.)<br>
+  </li>
+  <li>Module options (UID/GID ranges)<br>
+  </li>
+</ul>
+All static options have a describing comment in the configuration file
+to make it easier for the user to modify the values. The dynamic
+options provided by the modules do not include a comment.<br>
+<br>
+<h2>Master configuration file</h2>
+LAM stores the default configuartion profile and a master password in <span
+ style="font-style: italic;">config/config.cfg</span>.<br>
+The master password is verified when the user wants to create/delete
+configuration profiles.<br>
