ruby-on-rails - 什么是 Rails3 应用程序构建器？

Question

根据 Rails 的使用情况:

$ rails new --help
Usage:
  rails new APP_PATH [options]

Options:
  -b, [--builder=BUILDER]        # Path to a application builder (can be a filesystem path or URL)
      [--old-style-hash]         # Force using old style hash (:foo => 'bar') on Ruby >= 1.9
      [--skip-gemfile]           # Don't create a Gemfile

这个“应用程序构建器”指的是什么？它与应用程序模板(-m 选项)相比如何？

Descriptions in API Doc

The application builder allows you to override elements of the application generator without being forced to reverse the operations of the default generator.

简而言之，您可以在创建新的 Rails 应用之前定义默认的依赖项集。
