+#	Configuration variables (default values are below):
+#
+#	S	must be set to the top of the 'sys' tree.
+#	ZDST	may be set to the location of the directory where library
+#		objects are to be built.  Defaults to ${.OBJDIR}/lib/z.
+#	Z_AS	may be set to 'obj' to build a object from the library's
+#		object files.  (Otherwise, a library will be built.)
+#		Defaults to 'library'.
+#	ZMISCMAKEFLAGS
+#		Miscellaneous flags to be passed to the library's Makefile when
+#		building.  See library's Makefile for more details about
+#		supported flags and their default values.
