Source Code
;; Defined in /usr/src/emacs/lisp/textmodes/tex-mode.el.gz
;; `tex-mode' plays two roles: it's the parent of several sub-modes
;; but it's also the function that chooses between those submodes.
;; To tell the difference between those two cases where the function
;; might be called, we check `delay-mode-hooks'.

(define-derived-mode tex-mode text-mode "generic-TeX"
"Major mode for editing files of input for TeX, LaTeX, or SliTeX.
This is the shared parent mode of several submodes.
Tries to determine (by looking at the beginning of the file) whether
this file is for plain TeX, LaTeX, or SliTeX and calls `plain-tex-mode',
`latex-mode', or `slitex-mode', accordingly. If it cannot be determined,
such as if there are no commands in the file, the value of `tex-default-mode'
says which mode to use."
