^^^^^ This is the most important one. 

Why does global -u not do an incremental tags? I gave an example in my
first post.

Is this understandable?

The main problem is that "global -u" does NOT do an incremental update
for files already tagged using gtags -f gatgs-files. It tags ALL files
in that directory.

The problem is, for example, that I keep certain gnus files in my
.emacs.d. I generate a small GTAGS using "gtags -f gtags.files" BUT when
I save a .el file the onsave for emacs-lisp calls "global -u" which tags
ALL files in .emacs.d. Is this clearer?

How do I tell global only to tag *.el and *.org for example from the config 
file?

The emacs extensions doesnt allow selection of a $phpvariable. Have you
tried it? I am talking from within emacs.
