optparse-helper (hackage): The optparse-applicative package, as well as optparse-simple, has some undesirable behavior by default, and is quite verbose. This package exists to work around those two.  For instance:  optparse-applicative does not show help on error by default.  optparse-applicative does not disambiguate commands. So, if you have a command my-executable foobar, but your user runs my-executable f, optparse-applicative will not disambiguate this by default.  For more specific documentation, see the module documentation for Options.Applicative.Helper.
