There are a variety of Haskell libraries which are implementable
 through a common interface: self-describing parsers:
 .
  * A formlet is a self-describing parser.
  * A regular old text parser can be self-describing.
  * A command-line options parser is a self-describing parser.
  * A MUD command set is a self-describing parser.
  * A JSON API can be a self-describing parser.
 .
 This package provides a library for the Haskell programming language.
