Re: [9fans] mbits manpage

[geoff]

mbits(6) existed in Tenth Edition Unix but I can't find any evidence
that it was ever part of Plan 9.  The actual macros,
/sys/lib/tmac/tmac.bits, do exist in Plan 9, but they assume the
existence of a postprocessor named /usr/lib/btroff.  mpictures(6) is
probably the closest modern analogue of mbits, and is suggested as an
alternative in mbits(6).
