                      3: This file is intended to be a brief introduction to the build
                      4: process and a reference on what to do if something doesn't work.

                     16:        see pre-generated .txt and .html versions) describes the build
                     17:        procedure in great detail.  BUILDING, and the USE_NEW_TOOLCHAIN
                     18:        build process, are intended in the long run to replace this
                     19:        manual update log.

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

                     29:        prevented this was corrected.
