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. see http://www.haskell.org/ for more information on haskell.
