Standalone compiler, libraries and scripts
These tools allow you to build C++ libraries and applications targeting Windows desktop.
They are the same that you get with Visual Studio 2015 but they come in a scriptable standalone installer that only lays down the tools you need to build C++ projects.
Python: Install non-pure Python packages or compile a Cython or Pyrex file.
Node.js: Use native add-ons in Node.js with node-gyp.
Rust: Build Rust for Windows for use with the MSVC ABI.
