Basic script repository?

Hello,

Is there a basic script repository somewhere? Has someone culminated all the basic every day functions and generously shared them to the world?

I ask because although Unity scripting offers very deep access to all users, for many cases a level designer is just going to need a small set of simple scripts. E.g. Play sound on hitting a trigger:

function OnTriggerEnter() {
    audio.Play();
}

Sorry if this is a supersimple question, but again, my google skills fail me.
