<?php
// How to remove the piwik/ directory if it does not work in FTP?
// 1) Download and upload this file to your webserver
// 2) Put this file in the folder that contains the piwik/ directory (above the piwik/ directory)
//    For example if the piwik/ folder is at http://your-site/piwik/ you put the file in http://your-site/uninstall-delete-piwik-directory.php
// 3) Go with your browser to http://your-site/uninstall-delete-piwik-directory.php
// 4) The folder http://your-site/piwik/ should now be deleted!
// We hope you enjoyed Piwik. If you have any feedback why you stopped using Piwik, 
// please let us know at hello@piwik.org - we are interested by your experience
