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