+.Nm cc
+.Op Ar flags
+.Ar files
+.Fl lcurses ltermcap
+.Op Ar libraries
+.Sh 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
+.Fn refresh
+tells the routines to make the current screen look like the new one.
+In order to initialize the routines, the routine
+.Fn initscr
+must be called before any of the other routines that deal with windows and
+screens are used.  The routine
+.Fn endwin
+should be called before exiting.
