ajaxtoolkit scripts

Hi,

I'm using asp.net ajax toolkit in my application but it seems to be adding too many javascript/css files using script/web resources.

I want to combine all those scripts in one file, my own custom scripts and the generated ones as well.

Is there any way to do that in asp.net 4.0, i know there is a feature of toolkit scriptmanager control to bundle the scripts, but the point is how do i know which scripts i need to add to it and how do i make sure that they dont keep embeded by asp.net...

is there anyway to do it?

thanks
