Usage:
  check_generated_ports.sh [mission-dir] [--port_base=N] [--keep-targets]

Options:
  --port_base=N   Base MOOSDB port for generated target checks.
                  pShare ports use N+200. Default: 9100.
  --keep-targets  Preserve generated targ_* files after the check.
  -h, --help      Show this help.
