Class SlideShowDumper

java.lang.Object
org.apache.poi.hslf.dev.SlideShowDumper
public final class SlideShowDumper extends Object
This class provides a way to "peek" inside a powerpoint file. It will print out all the types it finds, and for those it knows 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)
