Interesting Taps and Forks
A tap is Homebrew-speak for a Git repository containing additional formulae.
Homebrew has the capability to add (and remove) multiple taps to your local installation with the brew tap and brew untap commands; run man brew in your terminal for usage information.
Your taps are Git repositories located at $(brew --repository)/Library/Taps. As a normal user, you usually wonโt see homebrew/core here anymore and thatโs OK - normal usage is via the JSON API.
