+# Variables controlling this file:
+#
+# PROG				Name of program to generate.
+# SRCS				.c and .S files to compile.
+#
+# CFLAGS			Compile flags.
+# LDFLAGS			Link flags.
+# LIBS				Libraries to link with.
+# LIBDEPS			Full paths of LIBS for depending on.
+#
+# BINDIR			Directory under $(OSTREE) to install into,
+#                               e.g. /bin. Should have a leading slash.
+#
+# Note that individual program makefiles should only *append* to
+# CFLAGS, LDFLAGS, LIBS, and LIBDEPS, not assign them. Otherwise stuff
+# set by os161.config.mk will get lost and bad things will happen.
