Error on the example format

[DoubleNight]

As example, the command should be like: $ ./bin/hash-files -f '["package.json"]' -a sha256

But it would throw an error said Option "files" has a value that cannot be converted to an Object/Array: [package.json].

It should be $ ./bin/hash-files -f '[\"package.json\"]' -a sha256 instead.
