OCaml IDE

Looking for an IDE for OCaml on Mac.

(Obviously, I was not the first, see, e.g., here).

• Emacs (Aquaemacs)
• Download Tuareg
• Config Aquaemacs (see)
1. place both tuareg.el and camldebug.el somewhere in
   

   ~/Library/Preferences/Aquamacs Emacs/

2. Add to ~/Library/Preferences/Aquamacs Emacs/Preferences.el (from append-tuareg.el): 
   (setq auto-mode-alist (cons '("\\.ml\\w?" . tuareg-mode) auto-mode-alist))
   (autoload 'tuareg-mode "tuareg" "Major mode for editing Caml code" t)
   (autoload 'camldebug "camldebug" "Run the Caml debugger" t)

3. Append custom-tuaerg.el at the end of (the modified)
   ~/Library/Preferences/Aquamacs Emacs/Preferences.el
   

• Camelia (for students going from scheme to ocaml)
• Eclispe (a few plugins)
