when certain .mk files include other .mk files. This will remove the need for multiple include protection in some other makefiles around the tree (and helps some elf conditionals).

# The include file <bsd.subdir.mk> contains the default targets
|
|
# for building subdirectories.
|
|
#
|
|
# For all of the directories listed in the variable SUBDIRS, the
|
|
# specified directory will be visited and the target made. There is
|
|
# also a default target which allows the command "make subdir" where
|
|
# subdir is any directory listed in the variable SUBDIRS.

# DISTRIBUTION Name of distribution. [bin]
|

#
|
|
# SUBDIR A list of subdirectories that should be built as well.
|

# Each of the targets will execute the same target in the

# subdirectories.

# SUBDIR_CHANGE A directory-tree that contains overrides for

# corresponding build subdirs.

# Each override is a file containing one subdirname per line:

# 'subdirlist' is a pure override
|
|
# 'subdirdrop' drops directories from the build
|

# 'subdiradd' adds directories to the build
