                     24:        the various "files" files.  Bug fixes to config(8) are
                     25:        required in order for this to work properly.  Make sure
                     26:        to build and install in usr.sbin/config before attempting
                     27:        to build a new kernel.

                     35:        see pre-generated .txt and .html versions) describes the build
                     36:        procedure in great detail.  BUILDING, and the USE_NEW_TOOLCHAIN
                     37:        build process, are intended in the long run to replace this

                     40:        Users building a USE_NEW_TOOLCHAIN system should read the
                     41:        BUILDING document for caveats.  Generally, BUILDING supersedes
                     42:        UPDATING for these systems, as tool updating is taken care of

                     48:        prevented this was corrected.
                     49:
