Matching tools to xnu

How do I determine which version of the various tools to checkout in order to build a version of the kernel? For example, I'm running 10.1.5 - which has xnu 201.42.3. I can checkout xnu with tag Apple-201-42-3, but how does this relate to the tags on bootstrap_cmds for example?
