The Lubinsky-S-tags should be removed and users should be pointed to
either ctags or some other tags program. ctags is better than other
tags programs (including the one that comes with emacs/xemacs). But,
tags can be generated with any tags program that supports --regex.
The regex for ctags is shown below. Here is copy of email that I sent
before...
Note, ctags can only support splus definitions that are on a single
line. It can not currently handle multiple line definitions like
foofoo <-
## The foofoo function ...
function ( ... )

Subject: ess-mode 5.1.18; tags
I noticed that some attempt at doing tags is included in ess
under ess-5.1.18/etc/other/Tags/Lubinsky-S-tags
The ctags/etags at:
The official Exuberant Ctags web site at:
http://ctags.sourceforge.net
can be coaxed into doing tags:
/etc/ctags.conf
================
--verbose=yes
--totals=yes
--recurse
--langmap=asm:
--langdef=Splus
--langmap=Splus:.s.S.R.r.q
--regex-Splus=/^[ \t]*([^ \t<]+)[ \t]*<-[ \t\n\r]*function/\1/
================
bash% etags
RECURSING into directory "."
OPENING base.s as S language file
...
When using xemacs, you would need to add the appropriate tag file to
tag-table-alist.
(setq-default tag-table-alist
(delete-if-not
#'(lambda (x) (and (cdr x) (file-exists-p (cdr x))))
`(("\\.e\\(l\\|macs\\)\\'" . ,(concat "XEMACS-" emacs-program-version "_TAGS"))
("\\.[RSs]\\'" . "S_TAGS"))))

Well, we also can run it as part of a "regenerate tags" style script,
or at least include a script that people can use.
Yep. You could also put a link to the tags sourceforge web site so
people can download etags.
