 Visual Studio 2017 (2019 should also work, but I haven't tested it)
 
 ## Building
-For an uncompressed build using Visual Studio: open `demo.sln`, switch to the `Release|x86` configuration, and build/run the `demo` project.
-For a basic compressed build: run `build.bat` (with no arguments).
-To shrink the executable further (e.g. for release): run `build.bat` *again* with the argument `improve`. Warning: this could take a while!
-To reproduce an already-released build: place the corresponding repro file in the project root directory and run `build repro <repro_file_name>`.
