      build.sh:  
        build         Build the system as per ``make build''.  This option
                      implies the obj and tools operations.

        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.

        tools         Build and install the host tools from src/tools.
   
        install=idir  Install the contents of DESTDIR to idir, using ``make
                      installworld''.
   
        kernel=kconf  Build a new kernel.  The kconf argument is the name of a
                      configuration file suitable for use by config(1).  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).
   
        releasekernel=kconf
                      Install a gzip(1)ed copy of the kernel built by
                      kernel=kconf into RELEASEDIR/MACHINE/binary/kernel, usually
                      as netbsd-kconf.gz, although the ``netbsd'' prefix is
                      determined from the ``config'' directives in kconf.
   
        sets          Perform ``make sets''.
