Hello,

I am putting together a PDF archive of our corporate newsletters. I'd 
like to iterate though a directory of PDFs, read their metadata (title, 
description, etc.) and use this info to dynamically generate a RHTML 
index page. There are several Ruby PDF libraries out there but they seem 
inclined towards creating PDFs instead of reading them. Any 
recommendations on a library to read PDF metadata?

It would be neat to not only read metadata but also to pull the PDF's 
first page's thumbnail out as an image. This would allow dynamic 
creation of an index page that looks like this:

Any thoughts?

Thanks,
Ben
