Is it possible to use yii ar outside?

Hi, all

I recentlly find that yii ar is so great.I wonder if i can use it outside yii framework.precisely, can i use it in CI(codeigniter)?

If anyone has once done this before?

Thanks,qiang.Sorry for my laziness to not read the yii document.

I will try it out later~~~
