Thanks Steve for writing this, and I'll read it more carefully when my

I was actually a math major before I discovered computer science, and I

You _can_ just extend a JSON file without loading it, but it will not be
"fun".
Say the JSON file contains a top-level array. The final significant
character in it would be a ']'. So, you can read just a reasonably-sized
block from the end of the file, find the location of the final ']',

It depends largely on whether you want to (and have sufficient permissions)
to install for all users or just yourself.
If, on *nix, you're installing site-wide (for all users), typically you'd
