Anybody get the "drivers" feature working?

As described, CodeIgniter's drivers feature is very useful, but although the code was changed from version 2 to version 3, the documentation remained the same, and it doesn't work.

The documentation apparently didn't work for version 2 either, and a developer called Kevin Phillips had a good tutorial here: http://www.kevinphillips.co.nz/news/code...-tutorial/

Unfortunately, that tutorial no longer works either. Does anyone have updated documentation?

Hey, don't work without a PHP debugger. Several free IDEs have this features built in. Two are NetBeans and CodeLobster. Without a debugger, it's like you're driving with a blindfold on -- you are going to crash!
