> The avro-tools command line should have at least one way to test
> reading/writing with an evolved schema. This would be useful for testing
> schema evolution and reproducing errors or bug reports from the command line.
> A good candidate would be to add a {{--reader-schema}} option to the
> {{tojson}} tool (where the writer schema comes from the data file).
> Alternatively, the {{fragtojson}} already takes the writer schema and we
> could add {{--reader-schema-file}}.
