Makefile

#
# 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.
#
