synopsis:            Adds and Eq instance for Parsec's ParseError if needed
description:
  .
  A library to help with compatibility against Parsec versions. Adds an
  instance of `Eq` to the `ParseError` data type, if it's missing from the
  version of Parsec that you're compiling against.
  .
  To test Parsec's parsing, it's very useful to have an Eq instance for
  ParseError. This is included in Parsec versions >= 3.1.9, but you need
  to define it yourself in previous versions.
  .
  This simple library conditionally adds an Eq instance for ParseError
  only if the Parsec version being used is < 3.1.9. To use it, just add
  parseerror-eq to your cabal dependencies, and in the module where you want
  to compare ParseErrors,
  .
  > import Text.ParseErrorEq ()
  .
  The ParseError Eq instance will be imported if it is necessary, otherwise
  the ParseErrorEq module is empty, so nothing will happen. This ensures that
  your code that needs the ParseError Eq instance will work regardless of the
  Parsec version that it is compiled against.
