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 appeneded
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 ALL_SUBDIR_TARGETS for list of targets that will recurse.
29# 	Custom targets can be added to SUBDIR_TARGETS in src.conf.
