public final class SlideShowDumper
extends java.lang.Object

This class provides a way to "peek" inside a powerpoint file. It will print out all the types it find, and for those it know aren't atoms, what they contain To figure out what things are, and if they are atoms or not, used the list in hslf.record.RecordTypes To peek inside PPDrawings, which hold Escher drawings, we use the DDF package from POI (but we can fake it by using the Escher listings from hslf.record.RecordTypes also)
