# Interstate '76 - build & install all three launchers. Idempotent; run after any
# stub source change. Requires: Xcode CLT (swiftc), the Interstate 76 - Software (DxWnd).app wrapper
# already set up (see README).
#
#   1. Interstate 76 - Software (DxWnd).app          - THE game (DxWnd big-window mode, dxwnd.exe /R:1)
#   2. Interstate 76 - Glide-dgVoodoo-DXVK-Metal.app            - dgVoodoo Glide mode (bright 3dfx color, 2x res;
#                                  one-time pipeline break-in - see README)
#   3. Interstate 76 - DxWnd Settings.app    - DxWnd GUI for tweaking the profile
