    # by setting WINELOADER to point to the original binary. Additionally, the locations
    # of the 32-bit and 64-bit binaries must differ only by the presence of "64" at the
    # end, due to the logic Wine uses to find the other binary (see get_alternate_loader
    # in dlls/kernel32/process.c). Therefore we do not use wrapProgram which would move
    # the binaries to ".wine-wrapped" and ".wine64-wrapped", but use makeWrapper directly,
    # and move the binaries to ".wine" and ".wine64".
