> * ReadP style parser over ByteString input
> * Drop-in replacement for Text.ParserCombinators.ReadP
> * Fast
> * Good memory usage

Great work, Gracjan. I hope to try it out soon. I think this is the
first of the many bytestring parser projects started to actually get
released onto Hackage! Well done!
