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:

Additionally, to use the Python script in the documentation, you'll need to yum install python-matplotlib.
