The package-vt package

[Tags:bsd3, program]

This program is meant as a tool for suggesting version change of libraries. It tries to match official Package Versioning Policy.

See for details.

This version works by inspecting new/removed exported modules or entities. It doesn't currently check the types of exported elements.

Typical invocation:

 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
