/**
* Wave Framework <http://www.waveframework.com>
* Cleaner Script for the Server
*
* This is a maintenance script template. It works similarly to Cleaner tool, but is intended
* to be called by the server in order to automatically clean the filesystem folders. The only
* difference is that the log is shown only if the server itself makes the request and the
* 'cutoff' value cannot be sent with the request by default. Developer should change this
* script accordingly to make it suitable for use in whatever system it is implemented on.

/**
* CONFIGURATION
*
* You can write additional configuration and adjustments here to make the maintenance
* script work the way you want. By default it accepts values exactly like Cleaner tool
* does and the only value that is hardcoded is the timestamp value in order to protect
* the server from potential misuse of the script.
*/
// This is the value for how new files will the Cleaner script keep. If the last-modified
// timestamp on the file is older than this value, then the file gets deleted. The default
// value for cutoff is 2592000 seconds (30 days)
$cutoff=$_SERVER['REQUEST_TIME']-2592000;
// This is the mode that is used, it is a comma-separated list of what '/filesystem/' folders
// to clean. Here is a list of all possible modes: output, images, resources, custom, tags,
// sessions, messenger, errors, logs, tmp, limiter, tokens, backups, updates, data, userdata,
// keys, static,

/**
* EXECUTION
*
* The below code does not need tweaking unless you wish to add or modify the functionality
* of the Cleaner script. This script will print out a log, but only if the request is made
* from the servers own IP.
