More details on catalog files and "-a" parameter

[jaymichaud]

The README.md and the product help ("-h") show this brief description of the "-a" parameter:

-a <catalog_folder> Catalog folder for all catalog files. All files in this folder will be treated as catalog file for Win10 S mode.

I have not been able to find any additional information about this option. Every forum post I have found just says not to use it, but I cannot find any description of when one should use it.

Would you please provide additional content in the README.md and product help—either inline or as a link or links to other documentation—about how this option is intended to be used? This could include any or all of the following:

• Which scenarios require catalog files?
• Which scenarios optionally could use catalog files?
• How does one obtain or create the catalog files?
