    _\bU_\bl 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 -\b-t\bt
    option overrides the terminal kind specified in the environ-
    ment.  The file /_\be_\bt_\bc/_\bt_\be_\br_\bm_\bc_\ba_\bp 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, _\bu_\bl degenerates to
    _\bc_\ba_\bt(1).  If the terminal cannot underline, underlining is
    ignored.

    The -\b-i\bi option causes _\bu_\bl 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 _\bn_\br_\bo_\bf_\bf output stream on a crt-terminal.

    _\bN_\br_\bo_\bf_\bf usually outputs a series of backspaces and underlines
    intermixed with the text to indicate underlining.  No
    attempt is made to optimize the backward motion.
