{-| Import this module in your code to access the entire library's
    functionality:

> import Control.Error

    This module exports the entire library as well as useful exports from other
    standard error-handling libraries:

    * "Control.Error.Safe": Generalizes the @safe@ library, including 'Either',
      'EitherT', and 'MonadPlus' variations on total functions

    * "Control.Error.Script": Support for simple scripts that catch all errors
      and transform them to 'String's

    * "Control.Error.Util": Utility functions and conversions between common
      error-handling types

    * @Control.Monad.Trans.Either@: The 'EitherT' monad transformer

    * @Control.Monad.Trans.Maybe@: The 'MaybeT' monad transformer

    * @Data.Either@: 'Either' utility functions

    * "Data.EitherR": throw and catch functions, and their corresponding
      \"success\" monads

    * @Data.Maybe@: 'Maybe' utility functions

    * @Safe@: Total versions of partial Prelude functions

    This module does not re-export partial functions from other libraries.
