+       to  manage only part of the screen.  The bottom portion of
+       the screen, which is of adjustable size, is left uncolored
+       to  display the results from shell commands.  The top por-
+       tion of the screen colors filenames using  a  scheme  like
+       the  "color  ls" programs.  Attempting to manage the back-
+       ground color of the screen for this application would give
+       unsatisfactory  results  for  a  variety of reasons.  This
+       extension was devised after noting that color  xterm  (and
+       similar  programs)  provides a background color which does
+       not necessarily correspond to  any  of  the  ANSI  colors.
+       While  a special terminfo entry could be constructed using
+       nine colors, there was no mechanism provided within curses

+       different  problem:  support  for applications which would
+       use  environment  variables  and  other  configuration  to
+       bypass  curses'  notion  of the terminal's default colors,
+       setting specific values.
