mandoc


installing source instead of preformatted manpages
reversing a trend going on for 25 years, to cope with *roff slowness

works like a compiler, has a lint mode
shows errors clearly, manpage authors love it

parses mdoc and man

no preprocessors (like tbl) needed

outputs ascii, html/css, xhtml, postscript, pdf
all without external dependencies
including utf8, locales - can handle japanese manpages
