Sdk location for vanilla intellij

Hi,

I am creating scripts to set up Intellij IDEA instance for developers. I can install, run given project, manage plugins, etc.

I face a problem: I can't find where or how I can install sdk for Intellij platfrm (SDK used in project). Currently user that don't have previous settings have to do it manually.

Do you have any idea how I can do it programically?

I am using Intellij 13.1.1 Comunity Edition.
