     NAME
          ul - do underlining

     SYNOPSIS
          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.  Ul also
          translates overstruck characters to bold, where appropriate.
          The -t option overrides the terminal kind specified in the
          environment.  Ul uses information from the terminfo database
          to determine the appropriate sequences for underlining and
          emboldening.  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.


     EXAMPLES
          $ ul file01

          This command reads the file "file01" and translates
          occurances of underscores to the sequence which indicates
          underlining for the terminal in use.  If the terminal does
          not support underlining, ul displays the file just as cat
          would.

     BUGS
          For users of the Documenter's Toolkit software:  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.
