:func:`runsnake` requires the program ``runsnake``. Due to non
trivial dependencies (python-wxgtk, ...), installing it within the
Sage distribution is unpractical. Hence, we recommend installing
it with the system wide Python. On Ubuntu 10.10, this can be done
with::
> sudo apt-get install python-profiler python-wxgtk2.8 python-setuptools
> sudo easy_install RunSnakeRun
See the ``runsnake`` website for instructions for other platforms.
:func:`runsnake` further assumes that the system wide Python is
installed in ``/usr/bin/python``.
