Hack core without incurring divine retribution on pre-adolescent feline kind.
This module is not for the faint of heart. You will need to use Runkit, and chances are good that this will involve checking out code from the PHP CVS and building it with PECL. And once you've got all of that running, this module gives you the tools to let you shoot yourself in the foot.
Developers: To use this module (assuming you have runkit and the module is installed), you will need to implement
hook_kitten_bling() in your module. Currently,
hook_kitten_bling is fired in
hook_boot, which means that you cannot use this module to override early bootstrapping in Drupal.
For maximum irresponsibility with minimal effort, you can get Runkit precomiled for MAMP here: http://technosophos.com/content/php-5-runkit-mamp-172
To use kitten, you must have Bad Judgement already.
