# Very basic demonstration of handling archives, based on the description
# in PSD.doc/tutorial.ms.
#
# This test aims at covering the code, not at being an introduction to
# archive handling. That's why it is more complicated and detailed than
# strictly necessary.

ARCHIVE=	libprog.a
FILES=		archive.mk modmisc.mk varmisc.mk

MAKE_CMD=	${.MAKE} -f ${MAKEFILE}
RUN?=		@set -eu;

.if ${.PARSEDIR:tA} != ${.CURDIR:tA}
	@cd ${MAKEFILE:H} && cp ${FILES} [at]*.mk ${.CURDIR}
.endif
# The following targets create and remove files.  The filesystem cache in
# dir.c would probably not handle this correctly, therefore each of the
# targets is run in its separate sub-make.
