1# The include file <bsd.subdir.mk> contains the default targets
2# for building subdirectories.
3#
4# For all of the directories listed in the variable SUBDIRS, the
5# specified directory will be visited and the target made. There is
6# also a default target which allows the command "make subdir" where
7# subdir is any directory listed in the variable SUBDIRS.
8#
9#
10# +++ variables +++
11#
12# DISTRIBUTION	Name of distribution. [base]
13#
14# SUBDIR	A list of subdirectories that should be built as well.
15#		Each of the targets will execute the same target in the
16#		subdirectories. SUBDIR.yes and SUBDIR.yes.yes are
17#		automatically appended to this list.
18#
19# +++ targets +++
20#
21#	distribute:
22# 		This is a variant of install, which will
23# 		put the stuff into the right "distribution".
24#
25# 	See SUBDIR_TARGETS for list of targets that will recurse.
26#
27# 	Targets defined in STANDALONE_SUBDIR_TARGETS will always be ran
28# 	with SUBDIR_PARALLEL and will not respect .WAIT or SUBDIR_DEPEND_
29# 	values.
30#
31# 	SUBDIR_TARGETS and STANDALONE_SUBDIR_TARGETS can be appended to
32# 	via make.conf or src.conf.
