mandoc (UNIX manpage viewer)

mandoc is a suite of tools containing mandoc, the roff macro package
of choice for BSD manual pages, and man, the predominant historical
package for UNIX manuals.  It is small, ISO C, ISC-licensed, and quite
fast.

The tool set features mandoc, based on the libmandoc validating
compiler, to format output for UNIX terminals (with support for
wide-character locales), XHTML, HTML, PostScript, and PDF. It also
includes preconv, for recoding multibyte manuals; demandoc, for
emitting only text parts of manuals; mandocdb, for indexing manuals;
and apropos, whatis, and man.cgi (via catman) for semantic search of
manual content.

There is an environment variable called REPLACE_MAN, that if set to a
non-empty string, will instruct the slackbuild script to replace the
stock man package (you should remove(pkg) it first, though).

After installing, make sure to (re)create the mandoc specific "whatis"
database(s) in your manpath(s), eg.:
# mandocdb /usr/man /usr/local/man
... or, if you've chosen to replace man, then:
# makewhatis /usr/man /usr/local/man
