+There is an easy way and an hard way to read CLASS outputs. The easy one is via the Graphical User Interface CLASSGui (see section~\ref{part:GUI}). This is an user friendly approach but as it is graphical it comes with its limitations. The hard way allows to access anything in your scenario evolution. This last approach requieres to write a specific .cxx file in which you can access any information you want by using the objects and methods of CLASS libraries. A detailed example of this approach can be found in \$CLASS\_PATH/example/ReadOuput.cxx. You are encouraged to read carefully the comments in this file to learn how to access the data you want.
