This program is meant as a tool for suggesting version change of libraries. It tries to match official Package Versioning Policy.
See http://www.haskell.org/haskellwiki/Package_versioning_policy for details.
This version works by inspecting new/removed exported modules or entities. It doesn't currently check the types of exported elements.
package-vt module-ver-1.hs module-ver-2.hs
If you unpack modules with
cabal unpack you can use the following form:
# unpack modules cabal unpack package-1 cabal unpack package-2 package-vt module-1/module.cabal module-2/module.cabal
