synopsis:      A small compatibility shim for the transformers library
description:
  This package includes backported versions of types that were added to
  @transformers@ in @transformers-0.5@ for users who need strict
  @transformers-0.5@ compatibility, but also need those types.
  .
  Those users should be able to just depend on @transformers >= 0.5@ and
  @transformers-compat >= 0.7.3@.
  .
  Note: missing methods are not supplied, but this at least permits the types to be used.

flag five
  default: False
  manual: False
  description: Use transformers 0.5 up until (but not including) 0.5.3. This will be selected by cabal picking the appropriate version.

flag five-three
  default: True
  manual: False
  description: Use transformers 0.5.3. This will be selected by cabal picking the appropriate version.

flag mtl
  default: True
  manual: True
  description: -f-mtl Disables support for mtl for transformers 0.2 and 0.3. That is an unsupported configuration, and results in missing instances for `ExceptT`.

flag generic-deriving
  default: True
  manual: True
  description: -f-generic-deriving prevents generic-deriving from being built as a dependency.
               This disables certain aspects of generics for older versions of GHC. In particular,
               Generic(1) instances will not be backported prior to GHC 7.2, and generic operations
               over unlifted types will not be backported prior to GHC 8.0. This is an unsupported
               configuration.
