我们国产语言木兰

……出门看火伴，火伴皆惊忙：同行十二年，不知木兰是素贞。

没错，我们国产语言木兰上线发布了，真好！

你看这完美的图标！

再看这美妙的手感！

我准备为之惊呼！

等下，这个图标……

这不是Pyinstaller打包完的图标吗？！

我们掏出PyInstaller Extractor（https://github.com/NeoTim/PyInstallerExtractor，https://sourceforge.net/projects/pyinstallerextractor/）。

进行解包……

$ python pyinstxtractor.py ulang-0.2.2.exe

不愧是敢用Pyinstaller的语言

你好歹也加个图标啊！

让我们看看ulang.runtime.env节选
