/**
 * Initializes log record capture, in addition to merely printing it.
 * This allows you to call {@link #getRecords} and/or {@link #getMessages} later.
 * @param maximum the maximum number of records to keep (any further will be discarded)
 * @return this rule, for convenience

        final Formatter f = new SimpleFormatter(); // placeholder instance for what should have been a static method perhaps
