 * @mainpage Kea Developer's Guide
 *
 * Welcome to Kea Developer's Guide. This documentation is addressed at
 * either existing or prospective Kea developers and contributors, and
 * provides information needed to extend and maintain Kea.

 * If you wish to write "hook" code - code that is loaded by Kea at
 * run-time and modifies its behavior,  you should read the section
 * @ref hooksdgDevelopersGuide.
 *
 * Kea maintenance information is divided into a number of sections
 * depending on focus. Information on DHCP-specific topics can be found
 * in the @ref dhcpMaintenanceGuide.  General topics, are discussed in
 * @ref miscellaneousTopics.
 *
 * If you are a user or system administrator, rather than software engineer,
 * you should read the
 * <a href="http://kea.isc.org/docs/kea-guide.html">Kea
 * Administrator Reference Manual</a> instead. If you are using a beta or
 * development version of Kea, the
 * <a href="http://git.kea.isc.org/~tester/kea/guide/kea-guide.html">
 * development version of the manual</a> is recommended.
 *
 * Regardless of your field of expertise, you are encouraged to visit the
 * <a href="http://kea.isc.org/">Kea webpage (http://kea.isc.org)</a>
