;; Here is a complete example of the settings you would use for
;; iPython 0.11:

;; (setq
;;  python-shell-interpreter "ipython"
;;  python-shell-interpreter-args ""
;;  python-shell-prompt-regexp "In \\[[0-9]+\\]: "
;;  python-shell-prompt-output-regexp "Out\\[[0-9]+\\]: "
;;  python-shell-completion-setup-code
;;    "from IPython.core.completerlib import module_completion"
;;  python-shell-completion-module-string-code
;;    "';'.join(module_completion('''%s'''))\n"
;;  python-shell-completion-string-code
;;    "';'.join(get_ipython().Completer.all_completions('''%s'''))\n")

;; For iPython 0.10 everything would be the same except for
;; `python-shell-completion-string-code' and
;; `python-shell-completion-module-string-code':

;; (setq python-shell-completion-string-code
;;       "';'.join(__IP.complete('''%s'''))\n"
;;       python-shell-completion-module-string-code "")

;; Unfortunately running iPython on Windows needs some more tweaking.
;; The way you must set `python-shell-interpreter' and
;; `python-shell-interpreter-args' is as follows:

;; (setq
;;  python-shell-interpreter "C:\\Python27\\python.exe"
;;  python-shell-interpreter-args
;;  "-i C:\\Python27\\Scripts\\ipython-script.py")

;; That will spawn the iPython process correctly (Of course you need
;; to modify the paths according to your system).

;; Please note that the default completion system depends on the
;; readline module, so if you are using some Operating System that
;; bundles Python without it (like Windows) just install the
;; pyreadline from http://ipython.scipy.org/moin/PyReadline/Intro and
;; you should be good to go.
