How to generate an index of a PDF file showing basic information?

Question:Given an existing PDF document, I would like to tack on an index to the end of the file to show the pages, on which key words show up. It would be best if I don't have to give a list of words to look for and the list of words is automatically generated. However, if a list of words must be given, I can work with it. I'm looking to do this either through a C# library or a command line tool. It needs to run as part of another command line app.Is there anything out there that is capable of this? Is there any solution on VeryPDF?
