       ronment.   The  terminfo(4) file corresponding to is read to determine the appropriate sequences for underlining.  If the terminal is inca-
       pable of underlining, but is capable of a standout mode, the standout mode is used instead.  If the terminal  can  overstrike,  or  handles
       underlining automatically, degenerates to If the terminal cannot underline, underlining is ignored.
