      Composer is a tool for dependency management in PHP. It allows you to
      declare the dependent libraries your project needs and it will install
      them in your project for you.

notes:
    - Default options that are always appended in each execution are --no-ansi, --no-interaction and --no-progress if available.
    - We received reports about issues on macOS if composer was installed by Homebrew. Please use the official install method to avoid issues.
