[AUCTeX] AUCTeX indentation does not work

[Gibson Kurt]

I am new to AUCTeX and after several hours of research cannot get it  
to indent paragraphs on my system.  It is worthless if it will not  
indent for me.  What purpose does it serve if it will not even allow  
someone to indent code manually?  TAB does not even work so I could  
not even use it to indent manually.

All of the documentation on the web says that AUCTeX automatically  
indents LaTeX source.  Not only is that false, I cannot even get it  
to allow me to do it manually.

It does not even inherit the formatting or level of the prior  
section, etc.

I want it to indent something.  TAB will not indent anything.   
Changing the variable LaTeX-indent-line and LaTeX-indent-level seems  
to have no effect.  "M-x auto-fill-buffer" has no effect.

I have a mac with emacs 22.3 installed.  I cannot even find  
documentation to determine whether or not AUCTeX is even running.   
When I open a LaTeX document the minibuffer banner line says  
"[(PDFLaTeX/F Fill)]".  No mention of auctex.

The following is in the .emacs file:

(add-to-list 'load-path (expand-file-name "/sw/share/emacs22/site- 
lisp/auctex"))

;;; invoke the AUCTeX package (LaTeX support)
(require 'tex-site)
(setq TeX-auto-save t)
(setq TeX-parse-self t)
(setq-default TeX-master nil)
(load "auctex.el" nil t t)
(load "preview-latex.el" nil t t)

;;; customize AUCTeX
; enable auto fill mode for all docs
(add-hook 'LaTeX-mode-hook 'auto-fill-mode)


I verified that the load path contains AUCTeX files.

Thanks for any comments.
