From a system-installed copy of the toolchain, packages all the required bits
into a .zip file.
It assumes default install locations for tools, in particular:
- C:\Program Files (x86)\Microsoft Visual Studio 12.0\...
- C:\Program Files (x86)\Windows Kits\10\...
1. Start from a fresh Win7 VM image.
2. Install VS Pro. Deselect everything except MFC.
3. Install Windows 10 SDK. Select only the Windows SDK and Debugging Tools for
Windows.
4. Run this script, which will build a <sha1>.zip.
Express is not yet supported by this script, but patches welcome (it's not too
useful as the resulting zip can't be redistributed, and most will presumably
have a Pro license anyway).
