-- A general API for representation and manipulation of versions.
--
-- Versioning schemes are many and varied, so the version
-- representation provided by this library is intended to be a
-- compromise between complete generality, where almost no common
-- functionality could reasonably be provided, and fixing a particular
-- versioning scheme, which would probably be too restrictive.
--
-- So the approach taken here is to provide a representation which
-- subsumes many of the versioning schemes commonly in use, and we
-- provide implementations of 'Eq', 'Ord' and conversion to\/from 'String'
-- which will be appropriate for some applications, but not all.
