### ``--version`` (Or ``-v``)
If you run MCPI-Reborn with ``--version`` it will print its version to ``stdout``.
### ``--print-available-feature-flags`` (Client Mode Only)
If you run MCPI-Reborn with ``--print-available-feature-flags``, it will print the available feature flags to ``stdout`` and then immediately exit.
### Client Mode Only
#### ``--print-available-feature-flags``
This print the available feature flags (and their default values) to ``stdout`` and then immediately exit.
The feature flags are printed in the following format:
```

### ``--default`` (Client Mode Only)
If you run MCPI-Reborn with ``--default``, it will skip the startup configuration dialogs and just use the default values.
#### ``--default``
This will skip the startup configuration dialogs and just use the default values. This will use the cached configuration unless ``--no-cache`` is used.
### ``--only-generate`` (Server Mode Only)
If you run MCPI-Reborn with ``--only-generate``, it will immediately exit once world generation has completed. This is mainly used for automatically testing MCPI-Reborn.
### ``--benchmark`` (Client Mode Only)
If you run MCPI-Reborn with ``--benchmark``, it will enter a simple benchmark mode. This means automatically loading a newly generated world, then rotating the camera for a period of time. When it has finished, it will then exit and print the average FPS while the world was loaded. In this mode, all user input is blocked. However you can still modify rendering settings by changing feature flags.
#### ``--benchmark``
This will make MCPI-Reborn enter a simple benchmark mode. This means automatically loading a newly generated world, then rotating the camera for a period of time. When it has finished, it will then exit and print the average FPS while the world was loaded. In this mode, all user input is blocked. However you can still modify rendering settings by changing feature flags.
The world used will always be re-created on start and uses a hard-coded seed.
### ``--no-cache`` (Client Mode Only)
If you run MCPI-Reborn with ``--no-cache``, it will skip loading and saving the cached launcher configuration.
#### ``--no-cache``
This will skip loading and saving the cached launcher configuration.
#### ``--wipe-cache``
This will wipe the cached launcher configuration.
### Server Mode Only
#### ``--only-generate``
This will make MCPI-Reborn immediately exit once world generation has completed. This is mainly used for automatically testing MCPI-Reborn.
