+Rendering math equation using TeX
+=================================
+
+You can use TeX to render all of your matplotlib text if the rc
+parameter text.usetex is set.  This works currently on the agg and ps
+backends, and requires that you have tex and the other dependencies
+described at http://matplotlib.org/users/usetex.html
+properly installed on your system.  The first time you run a script
+you will see a lot of output from tex and associated tools.  The next
+time, the run may be silent, as a lot of the information is cached.
+
+Notice how the the label for the y axis is provided using unicode!
