About LaTeX/TeX modes

[Angelo Graziosi]

I notice that when in .tex documents one puts the statement 

\PassOptionsToPackage{...}{...}

before the 

\documentclass{...}

Emacs renders the buffers in TeX mode instead of LaTeX mode. This results a bit 
annoying because documents that do not need the '\PassOptionsToPackage' 
statement are classified as LaTeX-mode the other as TeX-mode and in tabbar one 
has each time to switch between these two groups.

I am wondering if the fact I use  AUCTeX from Elpa is the cause of this..

Ciao,
 Angelo.
