  22 # Kernel tags:
  23 # Tags files are built in the top-level directory for each architecture,
  24 # with a makefile listing the architecture-dependent files, etc.  The list
  25 # of common files is in ./Make.tags.inc.  Links to the correct tags file
  26 # are placed in each source directory.  We need to have links to tags files
  27 # from the generic directories that are relative to the machine type, even
  28 # via remote mounts; therefore we use symlinks to $SYSTAGS, which points at
  29 # ${SYSDIR}/arch/${MACHINE}/tags.

  31 # Note: only a couple of architectures are currently working right. Add more
  32 # to ARCH as you fix them. Use the i386 as a model.
