This section briefly describes the peculiarities of using Emacs built with
the GNUstep libraries on GNU/Linux or other operating systems, or on Mac OS X
with native window system support. For Mac OS X, Emacs can be built either
without window system support, with X11, or with the Cocoa interface. This
section only applies to the Cocoa build. Emacs 23 does not support Mac OS
Classic.

built either without window system support, with X11, or with the
Cocoa interface; this section only applies to the Cocoa build. Emacs
does not support earlier versions of Mac OS.
Emacs, when built on Mac OS X, uses the Cocoa application interface. For
various historical and technical reasons, Emacs uses the term @samp{Nextstep}
internally, instead of ``Cocoa'' or ``Mac OS X''; for instance, most of the
commands and variables described in the following sections begin with
@samp{ns-}, which is short for @samp{Nextstep}. NeXTstep was an application
interface released by NeXT Inc during the 1980s, of which Cocoa is a direct
descendant. Apart from Cocoa, there is another NeXTstep-style system:
GNUstep, which is free software. As of this writing, the GNUstep support is
alpha status (@pxref{GNUstep Support}), but we hope to improve it in the
future.
