+# OS/161 build environment: build a host-system program

+# Usage:
+#    TOP=../..
+#    .include "$(TOP)/mk/os161.config.mk"
+#    [defs go here]
+#    .include "$(TOP)/mk/os161.hostprog.mk"
+#    [any extra rules go here]
+#
+# Variables controlling this file:
+#
+# PROG				Name of program to generate.
+# SRCS				.c and .S files to compile.
+#
+# HOST_CFLAGS			Compile flags.
+# HOST_LDFLAGS			Link flags.
+# HOST_LIBS			Libraries to link with.
+#
+# HOSTBINDIR			Directory under $(OSTREE) to install into,
+#                               e.g. /hostbin. Should have a leading slash.
+#				If not set, the program goes in
+#				$(TOOLDIR)/hostbin instead.
+#
+# Note that individual program makefiles should only *append* to
+# HOST_CFLAGS, HOST_LDFLAGS, and HOST_LIBS, not assign them. Otherwise
+# stuff set by os161.config.mk will get lost and bad things will
+# happen.
