# This Makerules file is only used by top-level Makefiles
# in machine-dependent source trees.
#
# SRCTREES must contain the pathnames of all more-speific source trees.
# The first pathname is assumed to be the directory containing configstart,
# and is where the configure script is produced.
#
# SUBDIRS must be set to the complete list of subdirectories
# which contain Makefiles to descend into.
# The directories can be listed in any order.
#
# FIRST_SUBDIRS can be a subset of those subdirectories
# which must be built before all other subdirectories,
# in the order specified in FIRST_SUBDIRS.
#
# Similarly, LAST_SUBDIRS can be a subset of the SUBDIRS
# which must be built after all others,
# in the specified order.
#
# Naturally, FIRST_SUBDIRS and LAST_SUBDIRS should not overlap.
