Well, if you're storing them as strings, then duh, you need the
helper utilities.  If you store them as comparable tuples, then it's
not a problem. :-/

  # library.VERSION = (3, 14, 15)
  if library.VERSION < (2, 3, 18):
    complain()

It does become harder to mark things as alpha/beta/pre/rc, but
something Enum-like might suffice for that in a fourth field of the
tuple.
