Detailed Description

Test multi-threaded xAOD::FileMetaData writing

Read default test AOD and configure to write output stream with
xAOD::FileMetaData object. Set up to process 4 concurrent events. Inspect the
produced file for xAOD::FileMetaData metadata items.

    Typical usage example
        python -m xAODMetaDataCnv.TestWriteFileMetaDataAOD |tee log
