The installation instructions are in the readme.txt file. When this is run from OrCAD when creating a netlist, you can select which attribute will be the PADS part name, and you can pass over any other attribute you want too. It still works on v17.2 files.
There is also a script to pass attributes from PADS back to OrCAD, but I have not used it.
I am not the author, but this has been working for over 6 years, so it's pretty reliable.
