mandown converts markdown formatted manuals into the troff(1) based format that is used by man(1) on most systems.
Man pages are useful, but often neglected by modern software developers. This may be because man pages need to be written in a typesetting language seldom used by most developers (outside of man), or it may be that the software being written is written in a language that can be used on non-UNIX systems and the effort of writing extra documentation for a subset of users isn't perceived as worth the effort.
Writing the documentation in markdown addresses both of these problems. Modern software developers are already likely familiar with it, and it's consumable without any special software on non-UNIX systems.
By default, mandown will take any markdown file passed to it, try to parse it,
normalize the sections/whitespace, and print it to the screen in a format
similar to running man <cmd>. With the -t option, it will print it as troff
macros instead of human-readable format.
See mandown.1.md for an example.
