Putting on my Emacs Apostle hat, I find in my work with my colleagues 
that they have difficulties in running etags.  For a complex project, a 
command such as this:

	find /project/root -name '*.[ch]' | xargs -n 2000 etags

let alone the complications with additional file-name extensions like 
.cpp etc., is typically beyond many users' knowledge.  Since they don't 
know what the command is, they can't put it into their Makefiles, 
either.  Non-Unix platforms introduce an additional complication into 
this (no `find' installed etc.)

So perhaps it could be a good idea to have an Emacs command that would 
accept a few inputs, like the top-level directory and whether to recurse 
into its subdirectories, and will then run etags as appropriate.
