+# 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".
