¹ Homebrew will attempt to automatically derive the formula name and version, if it fails, you’ll have to make your own template. I suggest copying wget’s.

² This is done automatically when you install formula. It is useful for DIY installation, or in cases where you want to swap out different versions of the same package that you have installed at the same time.

³ This is generally not needed. However, it can be useful if you are doing DIY installations.
