How to register a client script resource at the bottom of webpage to enhance loading time

Question

I really hate the way Extender controls, Asp.net script controls that emit javascript all at the top of the web page and just was rethinking of any other way to emit it at the bottom similar to what, ClientScriptManager.RegisterStartupScript. On looking into this post by DanWahlin i think it is possible but i would have to handle all dirty work of seeing of script is included twice and making sure all necessary scripts are included in order. So my question boils down to this

"I am developing custom controls, Extender controls and i want all my scripts emitted to be at bottom of webpage, What options do you suggest and Why"

Note: These scripts and also css are embedded as web resources

Answer 1

Actually speaking you can't with the current implementation of the ajax extender controls. So i managed to rely on client script dependency framework like script.js instead. I did achieve that i wanted.
