  Supported:

    If you need a supported, but not enabled transpiler ('${chalk.red(
      figures.cross
    )}' below), just install
    it in the same folder dependency-cruiser is installed. E.g. 'npm i livescript'
    will enable livescript support if it's installed in your project folder.

  Transpilers:

${formatTranspilers()}
  Extensions:

${formatExtensions(main.allExtensions)}
