 Installing Cython
 =================
 
-Many scientific Python distributions, such as the Enthought Python
-Distribution [EPD]_, Python(x,y) [Pythonxy]_, and Sage [Sage]_, bundle
-Cython and no setup is needed. Note however that if your distribution
-ships a version of Cython which is too old you can still use the
-instructions below to update Cython. Everything in this tutorial
-should work with Cython 0.11.2 and newer, unless a footnote says
-otherwise.
