ProcessEntryContents() - this calls Entry.ProcessContents() on each entry. The default implementatoin does nothing. This can be overriden to adjust the contents of an entry in some way. For example, it would be possible to create an entry containing a hash of the contents of some other entries. At this stage the offset and size of entries should not be adjusted unless absolutely necessary, since it requires a repack (going back to PackEntries()). -10.
