      NAME
           ul - do underlining

      SYNTAX
           ul [ -i ] [ -t terminal ] [ name ...  ]

      DESCRIPTION
           Ul reads the named files (or standard input if none are
           given) and translates occurrences of underscores to the
           sequence which indicates underlining for the terminal in
           use, as specified by the environment variable TERM.  The -t
           option overrides the terminal kind specified in the
           environment.

           Ul uses curses(3X) and terminfo(4) to determine the
           appropriate sequences for underlining.  If the terminal is
           incapable of underlining, but is capable of a standout mode
           then that is used instead.  If the terminal can overstrike,
           or handles underlining automatically, ul degenerates to
           cat(1).  If the terminal cannot underline, underlining is
           ignored.

           The -i option causes ul to indicate underlining onto by a
           separate line containing appropriate dashes `-'; this is
           useful when you want to look at the underlining which is
           present in an nroff output stream on a crt-terminal.

      BUGS
           Nroff usually outputs a series of backspaces and underlines
           intermixed with the text to indicate underlining.  No
           attempt is made to optimize the backward motion.
