+#: Instantiate a Homebrew build environment. Uses our years-battle-hardened
+#: Homebrew build logic to help your `./configure && make && make install`
+#: or even your `gem install` succeed. Especially handy if you run Homebrew
+#: in an Xcode-only configuration since it adds tools like `make` to your `PATH`
