[Haskell-cafe] Listing native package requirements based on cabal information

[Alexander V Vershilov]

I personally not sure about the one right solution, as there are a plenty
of different approaches and rules that are applied
system wide, and heavily depend on the underlying package system. Of cause
implementation of the new nice features like running
arbitrary script, but I personally don't know of many good examples that
can make life much easier without introducing
additional problems.

I'll try to follow up this thread and ready to share our experience and
solutions.
