     ___________________________________________________________________________

   Someone prodded me into drawing up a timeline of the Emacs family tree. Let 
me
   know if you have any additions/corrections.

   This isn't intended to be a complete list of everything that has ever called
   itself Emacs -- as Craig Finseth's periodic posting of [3]emacs 
implementations
   shows, that would be much larger than this.

   However, I think this is fairly accurate for the GNU/Lucid/X Emacs part of 
the
   world, and their important predecessors. (An explanation of how and why the 
FSF
   Emacs / Lucid Emacs split came about is [4]over here.)

   For more detail about the early days, please see Bernie Greenberg's paper,
   [5]Multics Emacs: The History, Design and Implementation.

   There probably ought to be something about MULE and NEmacs in here, but I 
wasn't
   able to find any dates or numbers for those.

   I've drawn lines only where code is shared, not merely ideas.
