OK.  Sounds good, though I don't know what the details might look
like.  What are we likely to want to do for 1.6.0?

Good points.  Should the version be handled by the name, or should we
make the libraries more self-describing -- i.e. each has a "version"
function that reports its info.  (Probably not, but I figured while
we're discussing the topic we ought to consider all the options.)

Where does dynamic-link look?
