 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.
