-Software installation
-=====================
-
-The following guide gets you a virtual environment with all the necessary
-packages installed.
-
-
-Linux
------
-
-We assume Ubuntu (12.04 Quantal Quetzal or later) or Debian Linux (7.0 Wheezy
-or later), but if you manage to install everything on a different flavour
-that's also fine.
-
-You can [download Ubuntu here](http://www.ubuntu.com/) and either install it
-directly on your machine, or run it inside
-[VirtualBox](https://www.virtualbox.org/).
-
-Python version >= 2.7.3 and < 3.0 is required. This is installed by default on
-Ubuntu and Debian Linux. Note that we use Python 2, *not* Python 3.
-
-We need some system packages to be installed. For the following command, you
-need sudo rights:
-
-    sudo apt-get install -y \
-      curl python-qt4 libfreetype6-dev libpng12-dev python-cairo \
-      python-gtk2 python-gtk2-dev git gfortran
-
-From here on, everything is local for the current user.
-
-Install [virtualenv](http://www.virtualenv.org/) and
-[virtualenvwrapper](http://virtualenvwrapper.readthedocs.org/) using
-[Virtualenv Burrito](https://github.com/brainsik/virtualenv-burrito):
-
-    curl -s https://raw.github.com/brainsik/virtualenv-burrito/master/virtualenv-burrito.sh | $SHELL
-    source ~/.venvburrito/startup.sh
-
-Automatically
-[link PyGTK/Pycairo/PyQt system packages](https://gist.github.com/martijnvermaat/6111396/)
-into our virtual environments:
-
-    curl -s https://gist.github.com/martijnvermaat/6111396/raw/postmkvirtualenv > ~/.virtualenvs/postmkvirtualenv
-
-Create a virtual environment (named `programming-course`, but you could choose
-any name here):
-
-    mkvirtualenv programming-course
-
-Install IPython:
-
-    pip install ipython
-
-Install some of the other package we'll use:
-
-    pip install pyzmq tornado jinja2 pygments sphinx markdown nose
-    pip install numpy
-    pip install matplotlib
-    pip install biopython
-
-Define a default matplotlib backend:
-
-    mkdir -p ~/.matplotlib
-    echo "backend : GTKCairo" >> ~/.matplotlib/matplotlibrc
-

-
-    ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"
-    brew doctor
-    xcodebuild -license   # accept license
-
-Add user `bin`, and local Python to your `$PATH`:
-
-    echo 'export PATH="~/bin:/usr/local/share/python:/usr/local/bin:$PATH"' > .bash_profile
-    . .bash_profile
-
-We need some system packages:
-
-    brew install python --with-brewed-openssl
-    brew install gfortran
-
-Install [virtualenv](http://www.virtualenv.org/) and
-[virtualenvwrapper](http://virtualenvwrapper.readthedocs.org/) using

-any name here):
-
-    mkvirtualenv programming-course
-
-Install IPython (version 1.0):
-
-    pip install -e git+https://github.com/ipython/ipython#egg=ipython
-    # or after its 1.0 release: pip install ipython
-
-Install some of the other package we'll use:
