# $NetBSD: depsrc-usebefore.mk,v 1.8 2022/04/18 14:38:24 rillig Exp $
#
# Tests for the special source .USEBEFORE in dependency declarations,
# which allows to prepend common commands to other targets.
#
# If a target depends on several .USE or .USEBEFORE targets, the commands get
# appended in declaration order.  For .USE targets, this is the expected
# order, for .USEBEFORE targets the order is somewhat reversed.
#
# See also:
#	.USE
#	depsrc-use.mk

# Before make.h 1.280 from 2021-12-28, a .USEBEFORE target was accidentally
# regarded as a candidate for the main target.  On the other hand, a .USE
# target was not.
