-- Module : Distribution.Simple
-- Copyright : Isaac Jones 2003-2005
--
-- Maintainer : Isaac Jones <[email protected]>
-- Stability : alpha
-- Portability : portable
--
-- Explanation: Simple build system; basically the interface for
-- Distribution.Simple.\* modules. When given the parsed command-line
-- args and package information, is able to perform basic commands
-- like configure, build, install, register, etc.
--
-- This module isn't called \"Simple\" because it's simple. Far from
-- it. It's called \"Simple\" because it does complicated things to
-- simple software.
