;; pyreadline from http://ipython.scipy.org/moin/PyReadline/Intro and
;; you should be good to go.
;; The shell also contains support for virtualenvs and other special
;; environment modification thanks to
;; `python-shell-process-environment' and `python-shell-exec-path'.
;; These two variables allows you to modify execution paths and
;; enviroment variables to make easy for you to setup virtualenv rules
;; or behaviors modifications when running shells. Here is an example
;; of how to make shell processes to be run using the /path/to/env/
;; virtualenv:
;; (setq python-shell-process-environment
;; (list
;; (format "PATH=%s" (mapconcat
;; 'identity
;; (reverse
;; (cons (getenv "PATH")
;; '("/path/to/env/bin/")))
;; ":"))
;; "VIRTUAL_ENV=/path/to/env/"))
;; (python-shell-exec-path . ("/path/to/env/bin/"))
;; Pdb tracking: when you execute a block of code that contains some
;; call to pdb (or ipdb) it will prompt the block of code and will
;; follow the execution of pdb marking the current line with an arrow.
