Readme

Haskell supports exception hierarchies, but they require quite a bit of boilerplate to declare. This package leverages Template Haskell to automate declaration of large exception hierarchies.

This package requires GHC 7.6, as a bug in GHC 7.4 prevents expansion of Template Haskell splices using 'deriving Typeable'.
