Important changes in Mausezahn in Fedora: The binary executable for Mausezahn is available in Fedora as /usr/bin/mausezahn as opposed to /usr/bin/mz. This is done in keeping with the Fedora packaging guidelines with regards to problems that can occur in namespace with short names like "mz". For more reference see here: http://fedoraproject.org/wiki/PackageMaintainers/Packaging_Tricks#Use_of_common_namespace Additionally, to use the Python script in the documentation, you'll need to yum install python-matplotlib.
