In case you didn't know: if you really need some GNU tool, you can do `brew install coreutils` (assuming you use Homebrew).

The installed binaries will have their names prefixed with `g`; e.g. `gdate` instead of `date`.

If something you want isn't part of coreutils, you can often install it directly; e.g. `brew install gawk` or the weirdly-named `brew install gnu-sed` (which names its installed binary `gsed`... go figure.)

I know this; but can I teach every potential user of my scripts this same fact through documentation I have to maintain? What if: I write the code so that documenting it is easier?
