    This is a log4j 2 configuration file.

    It is highly recommended to keep the original "debug.log" as is, to make sure enough data is captured in case
    of errors in a format that neo4j developers can work with.

    All configuration values can be queried with the lookup prefix "config:". You can, for example, resolve
    the path to your neo4j home directory with ${config:dbms.directories.neo4j_home}.

    Please consult https://logging.apache.org/log4j/2.x/manual/configuration.html for instructions and
    available configuration options.
