1# The include file <bsd.subdir.mk> contains the default targets
2# for building subdirectories.
3#
4# For all of the directories listed in the variable SUBDIRS, the
5# specified directory will be visited and the target made. There is
6# also a default target which allows the command "make subdir" where
7# subdir is any directory listed in the variable SUBDIRS.

12# SUBDIR A list of subdirectories that should be built as well.
13# Each of the targets will execute the same target in the
14# subdirectories.

16# SUBDIR_ORDERED A list of subdirectories which also must be included in
17# in SUBDIR which have ordering requirements. If this
18# Make variable does not exist then all subdirectories are
