NSIS即NullsoftInstallSystem，一种制作安装程序的一个软件
搜索结果如下：
NSIS是“Nullsoft脚本安装系统”(NullsoftScriptableInstallationSystem)的缩写，它是一个免费的Win32安装、卸载系统，采用了简洁高效的脚本方式。它本来是一个由Nullsoft创建并用于作为Winamp及其插件发布的系统，但现已被上百个应用程序所应用，作为它们进行程序发布的工具。
NSIS创建的安装程序可以进行安装、卸载、设置系统设置、解压文件等等。几乎可以做所有事情。因为它基于脚本文件，所以你可以完全控制你的安装程序的每个部分。它的脚本语言支持变量、函数、字串处理，就像是一个普通的程序语言-但其仅设计用来创建安装程序。
