+ BUILDFILE
+                Use a different build file name than the platform default
+                ("Makefile" on Unixly platforms, "makefile" on native Windows,
+                "descrip.mms" on OpenVMS).  This requires that there is a
+                corresponding build file template.  See Configurations/README
+                for further information.
