#
# 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 deviates from the tutorial style of
# several other tests.

ARCHIVE=	libprog.a
FILES=		archive.mk archive-suffix.mk modmisc.mk ternary.mk varmisc.mk
