Because the D0DAD event catalogs and d0dad files are binary data,
a formatted dump utility has been written. The command
$ d0dad /mode=dump file_name
will print an ascii summary of the file file_name. Here
file_name is the name of either an event catalog or a d0dad file.
In addition to the /event and /run options as
described above, this command also accepts
the /event option without any event number.
In this case, the summary listing is changed to include information for every
event in the catalog or d0dad file.
