1 # from: @(#)bsd.subdir.mk 5.9 (Berkeley) 2/1/91
4 # The include file <bsd.subdir.mk> contains the default targets
5 # for building subdirectories.
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.
15 # DISTRIBUTION Name of distribution. [base]
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
25 # This is a variant of install, which will
26 # put the stuff into the right "distribution".
28 # See SUBDIR_TARGETS for list of targets that will recurse.
30 # Targets defined in STANDALONE_SUBDIR_TARGETS will always be ran
31 # with SUBDIR_PARALLEL and will not respect .WAIT or SUBDIR_DEPEND_
34 # SUBDIR_TARGETS and STANDALONE_SUBDIR_TARGETS can be appended to
35 # via make.conf or src.conf.
