[ESS] Cheating ESS to recognize maxima as an ESS process

[Richard M. Heiberger]

There are two steps:

1. Tell the shell buffer running maxima how to receive commands from ESS.
   Do this with
   M-x ess-add-ess-process

2. Tell the buffer holding your maxima code how to send commands.
   Do this with
   M-x S-mode

Now start using C-c C-n and related commands.  You will be prompted for
an ESS process.   Answer shell.


Sending lines will now work.  The editing and font-lock will be according
to the rules appropriate for S.  Writing a maxima-mode for editing is a
different, and more difficult, task.
