Rules

OK, so what are the ``official rules'' for straightedge and compass constructions? For example, can marks be made on the straightedge? Can you hold the compass against the straightedge to use it as a measuring device for one particular length? If you have a circle drawn already, can you put a straightedge against it so that it just touches (is tangent to) the circle? Et cetera.
