#
# The include file <bsd.subdir.mk> contains the default targets
# for building subdirectories. It has the same seven targets
# as <bsd.prog.mk>:
#	all, clean, cleandir, depend, install, lint, and tags.
#
# 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.
#
#
# +++ variables +++
#
# 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.
#
# +++ targets +++
#
#	distribute:
# 		This is a variant of install, which will
# 		put the stuff into the right "distribution".
#
#	afterdistribute, afterinstall, all, beforeinstall, checkdpadd,
#	clean, cleandepend, cleandir, depend, install, lint, maninstall,
#	obj, objlink, realinstall, tags
