Extension:ViewFiles

The ViewFiles extension allows users to view the contents of a limited set of files made available by the system administrator. A possible use for this extension would be to enable your users to see the current contents of your configuration files (e.g. LocalSettings.php and InitialiseSettings.php) or customized skin files so that they could better assist with troubleshooting and make recommendations for configuration changes. Don't forget, if you're going to use this to display files such as LocalSettings.php that contain sensitive data, you'll want to get that data out of webroot before exposing those files to the world.
