#
# 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.
#
#
# +++ variables +++
#
# DISTRIBUTION	Name of distribution. [base]
#
# 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".
#
#	afterinstall, all, all-man, beforeinstall, checkdpadd,
