+Command line scripts for Visual Studio compilation without IDE
+==============================================================
+
+Here are a few command lines for reference :
+
+### Build with Visual Studio 2013 for msvcr120.dll
+
+Running the following command will build both the `Release Win32` and `Release x64` versions:
+```batch
+build.VS2013.cmd
+```
+The result of each build will be in the corresponding `bin\Release\{ARCH}\` folder.
+
+If you want to only need one architecture:
+- Win32: `build.generic.cmd VS2013 Win32 Release v120`
+- x64: `build.generic.cmd VS2013 x64 Release v120`
+
+If you want a Debug build:
+- Win32: `build.generic.cmd VS2013 Win32 Debug v120`
+- x64: `build.generic.cmd VS2013 x64 Debug v120`
+
+### Build with Visual Studio 2015 for msvcr140.dll
+
+Running the following command will build both the `Release Win32` and `Release x64` versions:
+```batch
+build.VS2015.cmd
+```
+The result of each build will be in the corresponding `bin\Release\{ARCH}\` folder.
+
+If you want to only need one architecture:
+- Win32: `build.generic.cmd VS2015 Win32 Release v140`
+- x64: `build.generic.cmd VS2015 x64 Release v140`
+
+If you want a Debug build:
+- Win32: `build.generic.cmd VS2015 Win32 Debug v140`
+- x64: `build.generic.cmd VS2015 x64 Debug v140`
+
+### Build with Visual Studio 2015 for msvcr120.dll
+
+This capability is offered through `build.generic.cmd` using proper arguments:
+
+**For Win32**
+```batch
+build.generic.cmd VS2015 Win32 Release v120
+```
+The result of the build will be in the `bin\Release\Win32\` folder.
+
+**For x64**
+```batch
+build.generic.cmd VS2015 x64 Release v120
+```
+The result of the build will be in the `bin\Release\x64\` folder.
+
+If you want Debug builds, replace `Release` with `Debug`.
+
+### Build with Visual Studio 2017
+
+`build.VS2017.cmd`, contributed by [@HaydnTrigg](https://github.com/HaydnTrigg),
+will build both the `Release Win32` and `Release x64` versions
+of the first VS2017 variant it finds, in this priority order :
+Enterprise > Professional > Community
+
+Alternatively, it's possible to target a specific version,
+using appropriate script, such as `build.VS2017Enterprise.cmd` for example.
