0016    ==================
0017    This plugin behaves like a main program.
0018    Invoke the plugin with something like this:
0019
0020    geoPluginRun -plugin DD4hep_PersistencyExample_read_cond \
0021                 -output <file-name>

0023    Test the writing of a bunch of standard conditions objects
0024    to a native ROOT file.
