# from: @(#)bsd.subdir.mk 5.9 (Berkeley) 2/1/91
# $FreeBSD$
#
# The include file <bsd.subdir.mk> contains the default targets
# for building subdirectories.
#
# For all of the directories listed in the variable SUBDIRS, the
# specified directory will be visited and the target made. There is
# also a default target which allows the command "make subdir" where
# subdir is any directory listed in the variable SUBDIRS.
#
#
# +++ variables +++
#
# DISTRIBUTION Name of distribution. [base]
#
# SUBDIR A list of subdirectories that should be built as well.
# Each of the targets will execute the same target in the
# subdirectories. SUBDIR.yes is automatically appeneded
# to this list.
#
# +++ targets +++
#
# distribute:
# This is a variant of install, which will
# put the stuff into the right "distribution".
#
# See SUBDIR_TARGETS for list of targets that will recurse.
#
# Targets defined in STANDALONE_SUBDIR_TARGETS will always be ran
# with SUBDIR_PARALLEL and will not respect .WAIT or SUBDIR_DEPEND_
# values.
#
# SUBDIR_TARGETS and STANDALONE_SUBDIR_TARGETS can be appended to
# via make.conf or src.conf.
