      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 occurances 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.  The file /etc/termcap is read 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.

      AUTHOR
           Mark Horton wrote ul.  The -i option was originally a option of  the
           editor ex(1), then an iul command.

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