Manual pages, also called man pages, are a well supported, popular way to document software in Unix, BSD, and GNU/Linux operating systems. A text formatter program is required to process the intrinsic formats of man pages into other formats suitable for viewing. GNU/Linux systems typically use groff and some BSD systems, like OpenBSD for example, use mandoc suite of programs as a text formatter. To view man pages in Windows, however, you still need a formatting program. Hence we have decided to build for Windows the main programs of mandoc suite and put together the binaries for download with a short explanation on usage and building from sources.
