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 a library for the Haskell programming language.
