+# $NetBSD: readline.buildlink3.mk,v 1.1 2013/07/15 01:54:25 ryoon 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)
+#
+# === Variables set by this file ===
+#
+# READLINE_TYPE
+#	The name of the selected readline implementation, editline or
+#	readline.
