Metadata service
Metadata service for self-descriptive n-tuples
From README.md:
The metadata service adds information about n-tuple production into the resulting n-tuple. These information include job options and application name and version. They are named 'info' and saved inside the n-tuple.
The service can be included in the option file in the following way: ApplicationMgr().ExtSvc += [ "MetaDataSvc" ]
The info object can be opened and read with GaudiSvc/src/MetaDataSvc/readMetaData.C script. .x readMetaData.C The script requires a new version of ROOT.
