      build.sh:  
        build         Build the system as per ``make build''.  This option im-
                      plies the obj and tools operations.
   
        distribution  Build a full distribution as per ``make distribution''.
                      This option implies the build operation.
   
        release       Build a full release as per ``make release''.  This option
                      implies the distribution operation.
   
        makewrapper   Create the nbmake-MACHINE wrapper.  This operation is auto-
                      matically performed for any of the other operations.
   
        obj           Perform ``make obj''.
   
        tools         Build and install the host tools from src/tools.
   
        kernel=kconf  Build a new kernel.  The kconf argument is the name of a
                      configuration file suitable for use by config(8).  If kconf
                      does not contain any `/' characters, the configuration file
                      is expected to be found in the KERNCONFDIR directory, which
                      is typically sys/arch/MACHINE/conf.  The new kernel will be
                      built in a subdirectory of KERNOBJDIR, which is typically
                      sys/arch/MACHINE/compile or an associated object directory.
                      In order to ensure that the kernel is built using up-to-
                      date tools, it is strongly recommended that the tools be
                      rebuilt (using the tools operation).
   
        install=idir  Install the contents of DESTDIR to idir, using ``make
                      installworld''.

                not contain any `/' characters, the configuration file is ex-  
                pected to be found in the KERNCONFDIR directory, which is typi-  
                cally sys/arch/MACHINE/conf.  The new kernel will be built in a  
                subdirectory of KERNOBJDIR, which is typically  
                sys/arch/MACHINE/compile or an associated object directory.  In  
                order to ensure that the kernel is built using up-to-date  
                tools, it is strongly recommended that the tools be rebuilt  
                (using the -t option) in a separate invocation of build.sh pri-  
                or to using the -k option, or that the -t and -k options be
