// The installer on the command line, for scripts, SSH sessions and machines
// without the first-run UI:
//   SpeedBreaker --install <image|folder> [--dest <dir>]   copy and verify (default dest: GetUserPath()/game)
//   SpeedBreaker --verify <image|folder>                   hash-check every file without copying
//   SpeedBreaker --find-images [folder...]                 list disc images in the usual places (or these)
//   SpeedBreaker --where                                   print where the game install was found, and the data folders
//   SpeedBreaker --portable on|off                         copy the data and the game into SpeedBreaker's folder and keep
//                                                          them there (portable mode), or back (install/portable_switch.h)
// Ctrl-C cancels an install cleanly (the partial copy is removed).
