While Cardinal itself is licensed under GPLv3+, some modules/plugins used by it are not.
And since Cardinal builds the entire Rack and modules as a static library,
the more restrictive of the code licenses will apply to the final binary.
Bellow follows a list of all code licenses used in Cardinal and linked submodules.
| Name | License(s) | Additional notes |

| Carla | GPL-2.0-or-later | Used as plugin host within Cardinal |

Bellow follows a list of all licenses related to artwork and module panels, sorted by file name.
Licenses were retrieved from the official project's LICENSE, README or related files.
When * is used, it is meant as wildcard of all files, with potential exceptions mentioned afterwards.
When a license is uncertain, ??? is used.
Note: The "final" version of Cardinal MUST NOT be released with unclear licenses!
So all uncertainties need to be resolved ASAP.
