mandoc is a suite of tools compiling mdoc, the roff macro language of choice
for BSD manual pages, and man, the predominant historical language for UNIX
manuals. It is small, ISO C, ISC-licensed, and quite fast. The main component
of the toolset is the mandoc utility program, based on the libmandoc validating
compiler, to format output for UTF-8 and ASCII UNIX terminals, HTML 5,
PostScript, and PDF.
