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.

14#
15# DISTRIBUTION	Name of distribution. [bin]
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.
20#
21# SUBDIR_CHANGE A directory-tree that contains overrides for
22#               corresponding build subdirs.
23#		Each override is a file containing one subdirname per line:
24#                  'subdirlist'  is a pure override
25#		   'subdirdrop'  drops directories from the build
26#		   'subdiradd'   adds directories to the build
