This tool can be used to brute discover GET and POST parameters
Often when you are busting a directory for common files, you can identify scripts (for example test.php) that look like they need to be passed an unknown parameter. This hopefully can help find them.
The -off flag allows you to specify an offset (helps with dynamic pages) so for example, if you were getting alternating response sizes of 4444 and 4448, set the offset to 5 and it will only show the stuff outside the norm
