config-toml and associated packages

config-toml is a Haskell implementation of TOML 1.0.0, ideal for reading config files in an easily-human-readable, INI-like format. This repo additionally hosts a few other packages related to its development but unsuitable as subcomponents within that same (Hackage-visible) banner, such as benchmarks and matrix testing for the other Haskell TOML implementations; for the most part, simply carry on to the config-toml/ directory and operate within there, but if you are looking for those comparisons you'll find them in ecosystem-bench/.
