ipython 0.12.1+dfsg-0ubuntu1.1 (amd64 binary) in ubuntu precise

 IPython can be used as a replacement for the standard Python shell,
 or it can be used as a complete working environment for scientific
 computing (like Matlab or Mathematica) when paired with the standard
 Python scientific and numerical tools. It supports dynamic object
 introspections, numbered input/output prompts, a macro system,
 session logging, session restoring, complete system shell access,
 verbose and colored traceback reports, auto-parentheses, auto-quoting,
 and is embeddable in other Python programs.

 This package contains the basic terminal shell. For the qt console
 install ipython-qtconsole and for the html notebook install
 ipython-notebook.
