Each experiments develops its appropriate versioning system according to the guidelines
in the Massi File Specifications.
Below, the versioning systems of the various experiments are explained. This information
is extracted automatically from the Massi files. On the bottom of the page a table
lists the versions of the current Massi files for each fill number in each experiment.
Massi file versioning is available as of 2017.
