152 * The base framework handles all loading and module management.
155 * ISSO_NO_INPUT_SANITIZE - Disables the automatic input sanitizer
156 * ISSO_CHECK_POST_REFERER - Will check to make sure that on POSTed
157 * data, the referer matches the host
158 * ISSO_MT_START - Define the microtime() value at the top of your
159 * script and this will calculate the total execution
161 * SVN - Place SVN keywords (like $Id) to display the information on output
