关于Ipython的安装

我安装网上的方法下载了ipython之后找不到他们所说的在python安装目录下的windows批处理文件ipython.bak，请问是怎么回事？我在Scripts目录下只能找到ipython_win_post_install.pyo、ipython_win_post_install.pyc、easy_install-2.7-script.pyo、easy_install-script.pyo、easy_install-2.7-script.pyc、easy_install-script.pyc 求前辈指教

Scripts/ipython.exe或者Scripts/ipython-qtconsole.exe（如果你装了pyqt的话）
