-@subsection How do I run bash as a shell under NT Emacs?
+@subsection Is there a Cygwin port of GNU Emacs?
+
+Yes!  It uses the X11 (@file{http://cygwin.com/xfree/}) Windows
+interface.  From a remote login shell, this ``emacs -nw'' works fine.
+There is also a non-X11 version which just provides the text-only

+@subsection What about NT Emacs?

+If you want GNU Emacs with a native Microsoft Windows interface, but
+without X, then you must use the native Windows port, commonly known
+as ``NT Emacs''.  You get NT Emacs from any GNU mirror.  It is not
+available from Cygwin Setup.
