034 * {@link EnableAutoConfiguration Auto-configuration} for Spring Data's Neo4j
035 * Repositories.
036 * <p>
037 * Activates when there is no bean of type {@link Neo4jRepositoryFactoryBean} configured
038 * in the context, the Spring Data Neo4j {@link Neo4jRepository} type is on the classpath,
039 * the Neo4j client driver API is on the classpath, and there is no other configured
040 * {@link Neo4jRepository}.
041 * <p>
042 * Once in effect, the auto-configuration is the equivalent of enabling Neo4j repositories
043 * using the {@link EnableNeo4jRepositories} annotation.
