+      GNU Zile, which is a lightweight Emacs clone.  Zile is short
+      for Zile Is Lossy Emacs.  Zile has been written to be as
+      similar as possible to Emacs; every Emacs user should feel at
+      home.
+
+      Zile has all of Emacs's basic editing features: it is 8-bit
+      clean (though it currently lacks Unicode support), and the
+      number of editing buffers and windows is only limited by
+      available memory and screen space respectively.  Registers,
+      minibuffer completion and auto fill are available.  Function
+      and variable names are identical with Emacs's (except those
+      containing the word "emacs", which instead contain the word
+      "zile"!).
+
+      However, all of this is packed into a program which typically
+      compiles to about 130Kb.
