PDF Document Inspector for Mac

From Cheap Impostor:

PDF Document Inspector is a browser of a PDF document's contents. If you're not doing something pretty down-and-dirty with PDF, I can't imagine how it would be useful to you. On the other hand, if you are working with the innermost bits of a PDF file (like I was with Cheap Impostor), I can't think of any other tool out there that would help you figure out what's going wrong.

I wrote PDF Document Inspector as a part of developing my shareware application, Cheap Impostor. PDF Document Inspector is merely a wrapper over the PJX library I used to parse the input documents in Cheap Impostor. I found it invaluable for debugging, and I thought it might be useful to the community at large.
