-Background
-----------
-Within Emacs, the port and its code are referred to using the term
-"Nextstep", despite the fact that no system or API has been released
-under this name in more than 10 years. Here's some background on why:
-
-NeXT, Inc. introduced the NeXTstep API with its computer and operating
-system in the late 1980's. Later on, in collaboration with Sun, this
-API was published as a specification called OpenStep. The GNUstep
-project started in the early 1990's to provide a free implementation
-of this API. Later on, Apple bought NeXT (some would say "NeXT bought
-Apple") and made OpenStep the basis of OS X, calling the API "Cocoa".
-Since then, Cocoa has evolved beyond the OpenStep specification, and
-GNUstep has followed it.
-
-Thus, calling this port "OpenStep" is not technically accurate, and in
-the absence of any other determinant, we are using the term
-"Nextstep", both because it signifies the original inspiration that
-created these APIs, and because all of the classes and functions still
-begin with the letters "NS".
-
-(See http://en.wikipedia.org/wiki/Nextstep)
-
-This Emacs port was first released in the early 1990's on the NeXT
-computer, and was successively updated to OpenStep, Rhapsody, OS X,
-and then finally GNUstep, tracking GNU emacs core releases in the
-meantime.

- support was also added (also sans recognition).

- due to a translation problem. (UTF-8 based on
- work by Otfried Cheong; mac-roman from
