The AddComponentMenu attribute allows you to place a script anywhere in the "Component" menu, instead of just the "Component->Scripts" menu.

You use this to organize the Component menu better, this way improving workflow when adding scripts. Important notice: You need to restart.

// Javascript example
@script AddComponentMenu ("Transform/Follow Transform")
class FollowTransform extends MonoBehaviour {
}

// C# example:
[AddComponentMenu("Transform/Follow Transform")]
public class FollowTransform : MonoBehaviour
{
}
