Before this change, external commands, whether official or not, cannot use the `env:` DSL for `Homebrew::CLI::Parser` without adding their environment variable to `Homebrew::EnvConfig`. Instead, if the method is not defined, check the environment variable directly. This allows `env:` to be used as expected and allows simplifying some (new) code in e.g. `brew bundle`.
Library
This directory contains all the code run by the official brew command in Homebrew and all formulae (package descriptions) in taps (repositories containing formulae) in Taps subdirectories.
