I'm not one either, but I've been meaning to ask: why is etags in Emacs?
It does a generic job that isn't specific to Emacs, and other programs
that do this exist.

https://github.com/fishman/ctags seems active and has an Emacs developer
(Masatake YAMATO) as a contributor.

The question was asked before:
http://lists.gnu.org/archive/html/emacs-devel/2007-01/msg00075.html

It's my (superficial) impression that etags hasn't progressed much since
then. The majority of the changes seem to have been generic code-cleanup
stuff.

Is it that etags recognizes Emacs-specific C code that ctags does not?

My only motivation for asking is that it's good to reduce the number of
things that need to be maintained in Emacs, where possible.
