/*
 * The NSText class is now an abstract class.  When you allocate an
 * instance of NSText, an instance of NSTextView is always allocated
 * instead.
 *
 * But you can still subclass NSText to implement your own text
 * editing class not derived from NSTextView.  NSText declares general
 * methods that a text editing object should have; it has some helper
 * methods which are simple wrappers around the real basic editing
 * methods.  The real editing methods are not implemented in NSText,
 * which is why it is abstract. To make a working subclass, you need to
 * implement these methods, marked as "PRIMITIVE" below.
 *
 * The working subclass could potentially be implemented in absolutely
 * *any* way you want.  I have been told that some versions of Emacs can
 * be embedded as an X subwindow inside alien widgets and windows - so
 * yes, potentially if you are able to figure out how to embed Emacs
 * inside the GNUstep NSView tree, you can write a subclass of NSText
 * which just uses Emacs. */
