Today, we're excited to announce that we are open-sourcing Atom under the MIT License.

Much of Atom's functionality is provided by packages, and every Atom package has been open source since the day we launched the beta. Today, we're open sourcing the rest of Atom, which includes the core application, Atom's package manager, and Atom's Chromium-based desktop application framework, Atom Shell.

好赞！！而且除了编辑器本身，Atom shell 是不同于 node-webkit 的东西，这个本身就很值得研究了。。而且 atom shell 的主要开发者是个中国人，真是孤陋寡闻了 https://github.com/zcbenz

这下再也不用 hack 到它的代码里去看了，好爽。。

（PS：现在 Atom 好像已经支持 linux 和 windows 了，不过应该要自己编译： https://github.com/atom/atom#building）
