This will ask you a bunch of questions, and then write a package.json for you.
It attempts to make reasonable guesses about what you want things to be set to,
and then writes a package.json file with the options youve selected.
If you already have a package.json file, itll read that first, and default to
the options in there.
It is strictly additive, so it does not delete options from your package.json
without a really good reason to do so.
If you invoke it with -f, --force, -y, or --yes, it will use only
defaults and not prompt you for any options.
