26# Kernel tags:
27# Tags files are built in the top-level directory for each architecture,
28# with a makefile listing the architecture-dependent files, etc.  The list
29# of common files is in ./Make.tags.inc.  Links to the correct tags file
30# are placed in each source directory.  We need to have links to tags files
31# from the generic directories that are relative to the machine type, even
32# via remote mounts; therefore we use symlinks to $SYSTAGS, which points at
33# ${SYSDIR}/arch/${MACHINE}/tags.
34
35# Note: only a couple of architectures are currently working right. Add more
36# to ARCH as you fix them. Use the i386 as a model.

46# being, in the face of a constantly varying source tree, that this will be
