# $NetBSD: readline.buildlink3.mk,v 1.6 2019/09/02 02:23:02 rillig Exp $
#
# This Makefile fragment is meant to be included by packages that require
# any readline implementation instead of one particular one. The available
# readline/editline implementations are "editline" and "readline".
#
# If a package genuinely requires editline or readline, then it should
# directly include the appropriate buildlink3.mk instead of this file in
# the package Makefile.
#
# User-settable variables:
#
# READLINE_DEFAULT
# This value represents the type of readline we wish to use on the
# system. Setting this to "editline" means that the system libedit
# implementation is fine or pkgsrc "editline" should be used.
#
# Possible: editline readline
# Default: (depends)
#
# System-defined variables:
#
# READLINE_TYPE
# The name of the selected readline implementation, editline or
# readline.
