 It provides an easy way to define command-line parsers. Most users
 will want to use the System.Console.CmdArgs.Implicit module, whose
 documentation contains an example.
 .
 System.Console.CmdArgs.Explicit provides a way to write command-line
 parsers for both single mode programs (most programs) and multiple
 mode programs (e.g. darcs or cabal). Parsers are defined by
 constructing a data structure.
 .
 System.Console.CmdArgs.Implicit provides a way to concisely define
 command-line parsers, up to three times shorter than getopt. These
 parsers are translated into the Explicit data type.
 .
 System.Console.CmdArgs.GetOpt provides a wrapper allowing
 compatiblity with existing getopt parsers, mapping to the Explicit
 data type.
 .
 This package provides the documentation for a library for the Haskell
 programming language.
