1 - Setting the environment variables to use a specific software package
The software to analyze GLAST data is pretty complex. It involves several (similar but with subtle differences)

of working with a not properly set package (i.e. wrong libraries) are not negligible.
In this section you can find a set of scripts and a root macro that help setting the environment variables
in a more or less systematic and controlled way.
