-/**
- * Support class for local stories encoded in textual format, with a few rules:
- * <ul>
- * <li>The title must be on the first line</li>
- * <li>The author (preceded by nothing, "by " or "©") must be on the second
- * line, possibly with the publication date in parenthesis (i.e., "
- * <tt>By Unknown (3rd October 1998)</tt>")</li>
- * <li>Chapters must be declared with "<tt>Chapter x</tt>" or "
- * <tt>Chapter x: NAME OF THE CHAPTER</tt>", where "<tt>x</tt>" is the chapter
- * number</li>
- * <li>A description of the story must be given as chapter number 0</li>
- * <li>A cover may be present, with the same filename but a PNG, JPEG or JPG
- * extension</li>
- * </ul>
