Compile Godot for Windows easily

build_windows.bat

:: This script must be run from a Windows machine with
:: Visual Studio 2015, Python 2.7 and SCons installed at their
:: default locations. 7-Zip also needs to be installed (to compress editor binaries).

:: NOTE: You need Pywin32 to be installed to use multi-threaded compilation.
:: You may need to set "threads" to 1 for the first build, even if you have it installed.

:: Place this script at the root of your Godot Git clone.
:: CC0 1.0 Universal

:: set threads=%NUMBER_OF_PROCESSORS%
set threads=1
