deps 文件和 bin/vendors 脚本用于 Symfony 2.0.x，而 Symfony 2.1.x 已切换到 Composer.bin/vendors 脚本只是一个存根，因为在 Symfony 2.0.0 发布时 Composer 还没有准备好用于生产.

The deps file and bin/vendors script are used in Symfony 2.0.x, while Symfony 2.1.x has switched to Composer. The bin/vendors script was just a stub because Composer was not ready for production when Symfony 2.0.0 was released.
