 The Borland tools are the only ones that will, with the correct command-line switches for each game, deterministically compile this source code to executables that are bit-perfect to ZUN's original ones. Hence, they are the only supported build tools during all of the reconstruction phase.
 
 To build, simply run `build.bat` and follow the instructions.
