The cmdtheline package

[Tags:library, mit, test]

CmdTheLine aims to remove tedium from the definition of command-line programs, producing usage and help with little effort.

The inspiration was found in Daniel Bunzli's library.

CmdTheLine uses applicative functors to provide a declarative, compositional mechanism for defining command-line programs by lifting regular Haskell functions over argument parsers.
