I don't think we should worry too much about the semantics of the
different parts of the version number like that, I don't think we have
any algorithm for deciding which part of the version number to bump
when other than marketing-type reasons.

Usually when you have letters in a version number you don't put a dot
before then, so one would write 0.4cvs rather than 0.4.cvs for
instance. But we could break that convention if it would be helpful.

That's a useful chart but I really hope we don't really end up doing
that much branching. Also, I think we shouldn't have a "cvs" version
number at the tip of any branches that we don't expect to do further
development on. For instance, in the case of this 0.2 branch below, I
would expect the branch to be dead once 0.3 is released. Finally, the
chart below appears to imply some correlation between the branching
structure and the user-visible version numbers. I certainly hope we
are not committing to something like that.
