                     12:      This source tree contains a special subtree, ``tools'', which uses the
                     13:      host system to create a build toolchain for the target architecture.  The
                     14:      host system must have at least C and C++ compilers in order to create the
1.104   ! wiz        15:      toolchain (mmaakkee is not required); all other tools are created as part of
1.53      reed       16:      the NetBSD build process.  (See the environment variables section below
                     17:      if you need to override or manually select your compilers.)
