Great software, thank you.
Mangles multi-page documents if more than one rotation is needed to orient pages correctly. Only useful if one can do what is needed with a single 90-degree left or right rotation.
Thank you for the software! A friend just asked me to concatenate some pdfs for her and I was about to start my own code for that, decided to check sourceforge and found this great, simple and easy to install piece of code!!!!
