/**
* \mainpage KDE I/O Slave for the locate command
*
* \section intro_sec What is tdeio-locate?
* tdeio-locate is a KDE I/O Slave for the locate command.
* <p>This means that you can use tdeio-locate by simply typing in konquerors
* address box. You can e.g. type "locate:index.html" to find all files that
* contain "index.html" in their name.
* <p>There's even more: You can use tdeio-locate in all TDE applications, that
* accept URLs.
* <p>To find out more about tdeio-locate and to look for new versions, you
* should take a look at
* <a href="http://arminstraub.de/browse.php?page=programs_kiolocate">
* arminstraub.de</a>.
*
*
* \todo Implement locater:help.
*
* \todo If a directory matches then don't add its childs.\ At least make
* this configurable.
*
* \todo Use different icons for collapsed directories and make this
* configurable.
*
* \todo After updating the settings show a success html message instead
* of a blank page.
*
* \todo Check if locate's databases are outdated and warn about that.
*
* \todo Provide a means of updating the locate database (configurable
* of course).
