--   λtext is a general-purpose templating utility for text files.
--   
--   Turn plaintext files into lambdas - function application then becomes
--   concatenation.
--   
--   Please see the <a>github page</a> for more details.
--   
--   All credits go to Martin Grabmueller's <a>AlgorithmW</a> package for
--   the type inference algorithm used in λtext.
