[plug] using etags with emacs

[David Buddrige]

Hi all, 

I have two machines that I use.  machine 1 has the following version of 
etags: 

bash-2.04$ etags --version
Exuberant Ctags 5.0.1, Copyright (C) 1996-2001 Darren Hiebert
 Addresses: <darren at hiebert.com>, http://ctags.sourceforge.net
 Optional compiled features: +wildcards, +regex
bash-2.04$ 


Machine 2 has the following version of etags: 

[buddrid at mit243linux ]$ etags --version
etags (GNU Emacs 21.2)
Copyright (C) 1999 Free Software Foundation, Inc. and Ken Arnold
This program is distributed under the same terms as Emacs
[buddrid at mit243linux ]$ 


Using etags on machine 1 is fairly straight foreward.  I simply go to the 
root directory of the source-code I want to tag, and type: 

etags -R 

which recursively builds up a TAGS file for the current directory and all 
sub-directories.  (In this case -R stands for recursive). 

However, the -R switch on machine 2 (according to the man-page) stands for
 --no-regex 

I have been reading through the man page for machine 2's version of etags 
but have not been able to determine how to make it work over the entire 
source-code tree that I have.  The only way to *sort-of* make it work is to 
use the command:   find . | grep "\.[CH]$" to build up a list of all 
source-files and then pass that list of source files to the etags program; 
*however*, the TAGS file it generates takes me to the wrong symbols when I 
try to use it from within emacs - which makes it useless for all practical 
purposes. 

Has anyone used the etags command provided with emacs and knows how it 
works?  I've been messing around with the emacs version of the program 
on-and-off for a while now but haven't been able to make it do anything 
useful. 

thanks heaps guys 

David.
