These PLIST files have been autogenerated by mk/haskell.mk using
HS_UPDATE_PLIST=yes during a bulk build. They will help to track changes
to the packages. The Haskell packages didn't have PLIST files because
their paths contained package hashes. These hashes are now determined by
mk/haskell.mk, which makes it easy to generate easy to read PLIST files.
optparse-applicative is a haskell library for parsing options on the
command line, providing a powerful applicative interface for composing
these options.
optparse-applicative takes care of reading and validating the
arguments passed to the command line, handling and reporting errors,
generating a usage line, a comprehensive help screen, and enabling
context-sensitive bash completions.
