As Stefan already mentioned:

	/Applications/Emacs.app/Contents/MacOS/Emacs -nw

works as well! Use it with a shell alias or a shell function.

The other option is to check (compare) the emacs major version  
number. Apple's version of GNU Emacs without any windowing support is  
of version 21, the Carbon Emacsen are since some time of version 22:

	(cond ((< 21 emacs-major-version)
	    (progn
	      (message "This GNU Emacs is greater no. 21")
	      (some thing)
	    )
	      (some thing else, if needed)
	)

There are more conditionals.


Could be on Leopard, the coming Mac OS X 10.5, Apple's version of GNU  
Emacs will be 22. Then you could use emacs-minor-version.

There is also the symbol window-system. Without a windowing system  
it's nil, otherwise one of mac, ns, x11, or ? (don't know) for MS.

There's something the technicians need to learn from the artists. If  
it isn't aesthetically pleasing, it's probably wrong.
