 STATUS  
      This document is a work-in-progress.  As such, the information described  
      here may not match the reality of the build system as of this writing.  
      Once this document is completely in sync with reality, this paragraph  
      will be removed.  
   
      Discrepancies between this documentation and the current reality of  
      implementation are noted specially, as with the note below:  
   
      Note: This document applies only to platforms which use the new toolchain  
      as indicated by the default setting of TOOLCHAIN_MISSING in <bsd.own.mk>.  
      Platforms which have not yet been switched to the new toolchain should  
      continue building traditionally, using the notes specified in the file  
      UPDATING.

            Note: A couple of host toolchain components are not yet available  
            in the tools directory.  Also, some tools use non-POSIX, non-ANSI C  
            extensions and need to be standardized.  As a result, cross-compil-  
            ing from systems other than NetBSD is not currently supported.

                      Note that the mac68k port still uses an older method of

                      level directories for the machine type and source.
   
                      For most machine types, the CD-ROM will be bootable, and
                      will automatically run the sysinst(8) menu-based installa-
