Yii app and 3rd party in same webroot: rename index.php?

Newbie here.

Is it possible for Yii to share the same webroot with another script?

The only conflict is index.php

Is there a way to tell Yii I have renamed the web entry script ? Or is there a different method? Or am I crazy ?

The 3rd party scripts use web rewrites heavily, and index.php is hard-coded all over the place. So it would have to be Yii that has the flexibility to change the name of index.php

Thank you

Piece of cake. Rename index.php to anything you want. Awesome.

Somebody shoot me if I have fallen into a trap ;)
