dynamic fla creation

Hi all i have a question for you is it posible to create a layer for your fla file using actionscript or any other type of language? currently i have be given a project that requires the developemt of a fla file and provides a complete template for users to work with.

I have been to such sties as actionscript.org and www.tutorialized.com which have giving me much of the infromation required for developing both php,javascript,html,css and actionscript but none of these sites contain any information on creating layers via a scripted method. So i was wondering if it is posible or weather i am trying to do something that is not.


any sugestions on how to go about developing this functinality would be greatly apressiated.

cheers scott
