+# Toplevel makefile for OS/161.
+#
+#
+# Main rules:
+#    all (default):  depend and compile system; install into staging area
+#    rebuild:        likewise, but start with a clean slate.
+#    fullrebuild:    likewise, but start with a very clean slate.
+#
+# What all does, in order:
+#    tools:          depend and compile the tools used in build.
+#    includes:       install header files.
+#    build:          depend and compile the system.
+#
+# Other targets:
+#    depend:         just update make dependency information.
+#    tags:           generate/regenerate "tags" files.
+#    install:        install into $(OSTREE).
+#    clean:          remove generated files.
+#    distclean:      remove all generated files.
