[Duncan Coutts]

Thu May 29 02:22:44 PDT 2008  Duncan Coutts <duncan at haskell.org>
  * Add notThisVersion :: Version -> VersionRange
  Opposite of ThisVersion, it means /= x.y but is actually implemented
  as > x.y || < x.y as we do not have not or not equal as primitives.

    M ./Distribution/Version.hs -1 +4
