What is new?
Version 1.2.0 (2012-02-06)
Md2Man::Documentmodule now handles paragraph() nodes and

tagged, and normal paragraphs. A Redcarpet markdown parser need
only include that module and implement those hook methods in order
to benefit from md2man’s extensions to markdown syntax
README: mention features; revise markdown; cleanup.
