  HISTORY
       The tbl utility, a preprocessor for troff, was originally written by M.
       E. Lesk at Bell Labs in 1975.  The GNU reimplementation of tbl, part of
       the groff package, was released in 1990 by James Clark.  A standalone tbl
       implementation was written by Kristaps Dzonsons in 2010.  This formed the
!      basis of the implementation that is part of the mandoc(1) utility.
