        # A set of scripting engines that use the Babel transpiler.
        #
        # Engines:
        #
        # - `"babel"`, `"babel-file"` - A command.  This takes the contents
        #   of the resolved file, transpiles it, and outputs it into
        #   the output path, given by `#load_file_paths`.
        # - `"babel-inline"` - A block.  Similar to `"babel"`; however, it
        #   takes the block, uses {Parser::Node::Root#flatten} on it,
        #   transpiles the result, and adds that as an inline script.
        #
        # @note
        #   The libraries that these engines depend on are not required in
        #   by default; if any of these engines are used, the requisite
        #   libraries would have to be required by the `brandish.config.rb`
        #   file.
