Marked Man (mm) is a little program I wrote to view Markdown files like UNIX man pages. (Because who wants to leave their terminal just to open a file?)
It uses Pandoc to convert between Markdown and the
groff format. As a happy side-effect, this program can read basically anything as a man page: HTML, LaTeX, Word files (seriously), ePub, etc. Anything that Pandoc can read, Marked Man can handle.
