Simply put, destructuring in Clojure is a way extract values from a datastructure and bind them to symbols, without having to explicitly traverse the datstructure. It allows for elegant and concise Clojure code.

| Warning: "config" scripts exist outside your system or Homebrew directories. | |
| `./configure` scripts often look for *-config scripts to determine if | |
| software packages are installed, and what additional flags to use when | |
| compiling and linking. | |
| Having additional scripts in your path can confuse software installed via | |
| Homebrew if the config script overrides a system or Homebrew provided | |
| script of the same name. We found the following "config" scripts: | |
