Mandoc, which is what the BSDs and some other systems use for formatting manpages, has very good HTML output. In fact, the program used to be named “mdocml” because it was written to be a mdoc‐to‐HTML converter. Unfortunately the -man macros (as opposed to the modern -mdoc macros) aren’t that good for conversion to other formats like HTML, because they’re by nature presentation‐focused. All major troff implementations support the -mdoc macros, though, and -mdoc is much better suited. It’s what I write all my manpages in these days (and it’s a drop‐in replacement—replace foo.1 written in -man with foo.1 written in -mdoc and groff, man, etc will handle it instantly). I also like to convert manpages from -man to -mdoc, or write new pages for programs that don’t have one. It gets a little exhausting to convert long pages like the one you linked, though. Here’s some documentation on the format of -mdoc pages: http://mdocml.bsd.lv/man/mdoc.7.html http://mdocml.bsd.lv/man/mdoc.7.html
