Detecting attachments in PDF

[Sriram R]

Hello,

Subj: Validation to check if a PDF has attachments. 

I have a pdf with attachments inside. (I have attached the same to issue as well).

Using pdf-reader gem, how can i do the following: 
1. Detect if a pdf has attachments
2. If it has, how to find the details of the attachments.

If pdf-reader cannot perform this action, may i know any other gem/library which can get this information.
