-- | Simple Makefile parser
--   
--   This package provides a few <tt>Attoparser</tt> parsers and
--   convenience functions for parsing Makefiles. The datatypes used for
--   describing Makefiles are located in <a>Data.Makefile</a>. The parsers
--   and parsing functions are located in <a>Data.Makefile.Parse</a>. To
--   parse a Makefile in the current folder, simply run
--   <a>parseMakefile</a>. To parse a Makefile located at <tt>path</tt>,
--   run <a>parseAsMakefile</a> <tt>path</tt>.
