Substack writers, you and PT

Wouldn't it make sense to have it an extension? Just spontainously (without reading any instructions) I don't understand how to use "ls" and "cat" so I guess I'm missing something. It's been officially revised down to 6.8, but that's still a lot. Hope the residents of Kumamoto Prefecture stay safe and are able to edit local files. This is a fantastic preservation effort. It would be interesting to see if that is possible with this.
