.SH DESCRIPTION
The \fBuse_default_colors\fP and \fBassume_default_colors\fP
functions are extensions to the curses library.

For example, there are several implementations of the \fBls\fP program
which use colors to denote different file types or permissions.

.SH RETURN VALUE

This is a full-screen application which uses curses 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 portion of the screen colors filenames using a scheme like the
-"color ls" programs.
+\*(``color ls\*('' programs.
Attempting to manage the background color of the screen for this application
would give unsatisfactory results for a variety of reasons.
This extension was devised after
environment variables and other configuration to bypass curses'
notion of the terminal's default colors, setting specific values.
.SH PORTABILITY
-These routines are specific to ncurses.
+These routines are specific to \fI\%ncurses\fP.
They were not supported on
Version 7, BSD or System V implementations.
It is recommended that
any code depending on them be conditioned using NCURSES_VERSION.
