[dragonfly.git] / share / mk / bsd.subdir.mk

# 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 +++
#
# SUBDIR	A list of subdirectories that should be built as well.
#		Each of the targets will execute the same target in the
#		subdirectories.
#
# SUBDIR_ORDERED A list of subdirectories which also must be included in
#		in SUBDIR which have ordering requirements.  If this
#		Make variable does not exist then all subdirectories are
#		assumed to be strictly ordered.
#
# +++ targets +++

#	clean, cleandepend, cleandir, depend, install, lint, maninstall,
#	manlint, obj, objlink, realinstall, regress, tags
