off topic. .PDF manipulator

[callmark1]

Yikes. I find myself in need of a program that will manipulate about 3 dozen
PDF files in simple ways, such as changing the color of certain elements.
Don't have time to do the learning curve for Acrobat. Also the cost of
Acrobat is prohibitve since I will likely never need it again. Any
suggestions?

Thank you in advance

I don't think you can manipulate a PDF without Acrobat. Maybe something like
www.primopdf.com???
Ghostscript and GSView might be a solution.
