 * The RpfFrameEntry is a description of a RPF frame file that can be
 * used to quickly gain status about the frame. It is mainly created
 * by the table of contents handler (RpfTocHandler), and passed, in an
 * array of brothers in a RpfTocEntry, to the cache handler. The cache
 * handler will use the RpfTocEntry to figure out which frames are
 * needed to get the subframes it wants, and the RpfFrameEntry
 * supplies information to assist in loading that frame file.
