# $NetBSD: terminfo.buildlink3.mk,v 1.8 2019/09/02 02:23:02 rillig Exp $
#
# This Makefile fragment is meant to be included by packages that require
# any terminfo implementation instead of one particular one.  The available
# terminfo implementations are "terminfo" 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:
#
# TERMINFO_DEFAULT
#	This value represents the type of terminfo we wish to use on the
#	system.  Setting this to "terminfo" means that the system terminfo
#	implementation is fine.
#
#	Possible: terminfo, ncurses, pdcurses
#	Default: (depends)
#
# System-defined variables:
#
# TERMINFO_TYPE
#	The name of the selected terminfo implementation.
