A general library for representation and manipulation of versions.
This version of the module is forked from base, preserving the versionTags field of the Version type that will be removed in GHC 7.12 (cf. https://ghc.haskell.org/trac/ghc/ticket/2496).
Documents 'Read' instance parsing.
Parses empty strings in 'Read' instance.
This also has the consequence of allowing a Version to be consisted solely of 'versionTags'.
Implements 'IsString' Version instance.
- Adds base conversion functions.
