¹ To delete a specific version, just go to the folder in the Cellar and rm -rf it; alternatively, drag it to the trash in Finder.

² Homebrew tries to guess the formula name and version. If it fails, you’ll have to make your own template. I suggest copying wget ’s.

³ Symlinking is automatically performed when installing formulae. It’s useful for DIY installation, or swapping out versions of a package that has multiple installs.

⁴ This is generally not needed. However, it can be useful if you are doing DIY installations.
