Implementing PreLoad.py

I need to set environment variables on my slave prior to the job starting. I found the PreLoad.py script in the docs and this appears to do what I want.
However, I’m not sure on how to implement it? Does it get appended to the deadlinecommand submission script? Therefore resulting in:

“DeadlineCommand.exe [Job Info File] [Plug-in Info File] [Scene File] [PreLoad.py]”

Or is it another plug-in that is initiated and if so how do I go about that?

All info is greatly appreciated.

Hello,
All you need to do is copy the PreLoad.py script into the appropriate plugin directory in your repository.
