This package is used for communication between emacs and Maya. For
example you can use it together with Shuji Narazaki's mel-mode to
send pieces of mel code to Maya and get the results back in emacs.

To use this, insert in your ~/.emacs file:
(add-hook
 'mel-mode-hook
 (lambda ()
   (require 'etom)
   (setq etom-default-host "localhost")
   (setq etom-default-port 2222)
   (local-set-key (kbd "C-c C-r") 'etom-send-region)
   (local-set-key (kbd "C-c C-c") 'etom-send-buffer)
   (local-set-key (kbd "C-c C-l") 'etom-send-buffer)
   (local-set-key (kbd "C-c C-z") 'etom-show-buffer)))


You should have an open commandPort in Maya. You can do this with:
commandPort -eo -n ":2222";

Have fun!
