NAME
     curses - screen functions with optimal cursor motion

SYNTAX
     cc [ flags ] files -lcurses -ltermcap [ libraries ]

DESCRIPTION
     These routines give the user a method of updating screens with
     reasonable optimization.  They keep an image of the current
     screen, and the user sets up an image of a new one.  Then the
     refresh subroutine tells the routines to make the current screen
     look like the new one.  To initialize the routines, the routine
     initscr must be called before any of the other routines that deal
     with windows and screens are used.  The routine endwin should be
     called before exiting.
