modes not doing much

[YAD]

So far I've used Ruby mode and HTML mode.
No colors, no auto-indent on <rtrn>.

So what are the modes doing?  Vim and even the
Firefox source viewer have syntax-based colors.
Isn't Emacs supposed to do that too?

Also, Lisp .cl files and Python .py files are coming up in
Fundamental mode, while OCaml .ml files come up in Lisp mode.
What the heck is going on? :(
