# $NetBSD: curses.buildlink3.mk,v 1.22 2015/02/04 16:35:32 pho Exp $
#
# This Makefile fragment is meant to be included by packages that require
# any curses implementation instead of one particular one.  The available
# curses implementations are "curses" if built-in, "ncurses", and
# "pdcurses".
#
# If a package genuinely requires ncurses or pdcurses, then it should
# directly include the appropriate buildlink3.mk instead of this file in
# the package Makefile.
#
# === User-settable variables ===
#
# CURSES_DEFAULT
#	This value represents the type of curses we wish to use on the
#	system.  Setting this to "curses" means that the system curses
#	implementation is fine.
#
#	Possible: curses, ncurses, ncursesw, pdcurses
#	Default: (depends)
#
# === Variables set by this file ===
#
# CURSES_TYPE
#	The name of the selected curses implementation.
