Does "make sure you have this first" mean "install this if it's not present"
or "raise an exception if it's not present"? AFAICT PEP 376 does not
consider extras at all, and so does not have any standard way to store which
extras a distribution was installed with. So what's the standard way of
testing if "extra is available"?
