File Setup.jsx v3
Copyright (C) 2017, 2018 Johan Rydberg. All Rights Reserved.

A Photoshop Script to automate the file setup described in
"Commercial Retouching Workflow with Sef McCullough" from RGG EDU.

It expects you to have paths set up for your parts. If one of the paths is
called "SILO" then that will be used as group mask for all other masks.

The layer that is active when you invoke the script will be the one
used as base.

How to use:

Install it under Presets/Scripts in your Photoshop CC folder, and then
run it from File>Scripts menu (it should be listed there. don't forget
to restart Photoshop).

Or, you can use File>Scripts>Browse... and pick this file.

Notes:

  If you have a path named something like "GUIDE foo", only a guide
  will be created for the path.
