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.
8#

10# +++ variables +++
11#
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.
15#
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
19#                   assumed to be strictly ordered.
