How can I modify executable metadata through the command line?

Question

How can I modify these fields on an executable? I've found a few questions here on how to get these fields but none on how to set them. In addition, I need to be able to do this through a batch file or command line or something, as it will be part of an automated process.

Specifically, I need to change the "File description", "Product name", and "Copyright" fields.

If it helps, the file is an executable of a game built through Unity, and I have access to the source. I couldn't find any way to set these fields through Unity.

I am on Windows 7.
