Mueval is a Haskell interpreter. It uses the GHC API to evaluate
arbitrary Haskell expressions.

Importantly, mueval takes many precautions to defang and avoid
"evil" code. It uses resource limits, whitelisted modules, special
Show instances for IO, threads, processes, changes of directory, and
so on to sandbox the Haskell code.

It is, in short, intended to be a standalone version of Lambdabot's
famous evaluation functionality. For examples and explanations, please
see the README file.

Mueval is POSIX-only.
