1#	from: @(#)bsd.subdir.mk	5.9 (Berkeley) 2/1/91
2# $FreeBSD$
3#
4# The include file <bsd.subdir.mk> contains the default targets
5# for building subdirectories.
6#
7# For all of the directories listed in the variable SUBDIRS, the
8# specified directory will be visited and the target made. There is
9# also a default target which allows the command "make subdir" where
10# subdir is any directory listed in the variable SUBDIRS.
11#
12#
13# +++ variables +++
14#
15# DISTRIBUTION	Name of distribution. [base]
16#
17# SUBDIR	A list of subdirectories that should be built as well.
18#		Each of the targets will execute the same target in the
19#		subdirectories. SUBDIR.yes is automatically appended
20#		to this list.
21#
22# +++ targets +++
23#
24#	distribute:
25# 		This is a variant of install, which will
26# 		put the stuff into the right "distribution".
27#
28# 	See SUBDIR_TARGETS for list of targets that will recurse.
29#
30# 	Targets defined in STANDALONE_SUBDIR_TARGETS will always be ran
31# 	with SUBDIR_PARALLEL and will not respect .WAIT or SUBDIR_DEPEND_
32# 	values.
33#
34# 	SUBDIR_TARGETS and STANDALONE_SUBDIR_TARGETS can be appended to
35# 	via make.conf or src.conf.
