Create new composition and apply a name Adobe cs5 script

I need to extend the "smart import" script. I want to create a new composition.

then add each imported "element" to the composition as a track. one track p开发者_开发知识库er image\sequence that's imported.

So what I need to know is how to create a composition through script, and how to add a file sequence to it through scripting.

myComp = app.project.item(1);
myComp.layers.add (app.project.item(2));

I resolved it by using the script above. this assumes your composition is the only objects when starting. then I import, and add the second item (this is my imported object) to the composition.
