4# The include file <bsd.subdir.mk> contains the default targets
5# for building subdirectories. It has the same seven targets
6# as <bsd.prog.mk>:
7#	all, clean, cleandir, depend, install, lint, and tags.
8#
9# For all of the directories listed in the variable SUBDIRS, the
10# specified directory will be visited and the target made. There is
11# also a default target which allows the command "make subdir" where
12# subdir is any directory listed in the variable SUBDIRS.
13#
14#
15# +++ variables +++
16#
17# DISTRIBUTION	Name of distribution. [bin]
18#
19# SUBDIR	A list of subdirectories that should be built as well.
20#		Each of the targets will execute the same target in the
21#		subdirectories.
22#
23# SUBDIR_CHANGE A directory-tree that contains overrides for
24#               corresponding build subdirs.
25#		Each override is a file containing one subdirname per line:
26#                  'subdirlist'  is a pure override
27#		   'subdirdrop'  drops directories from the build
28#		   'subdiradd'   adds directories to the build

32#	distribute:
33# 		This is a variant of install, which will
34# 		put the stuff into the right "distribution".
