etags tags: TAGS

# Right now this just builds TAGS in each subdirectory.  emacs19 has the
# ability to use several tags files at once, so there is probably no need
# to combine them into one big TAGS file (like CVS 1.3 does).  We could
# (if we felt like it) have this Makefile write a piece of elisp which
# the user could load to tell emacs19 where all the TAGS files we just
# built are.
