LICENSE

SPDX-License-Identifier: AGPL-3.0-or-later OR BUSL-1.1

reng is dual-licensed under the AGPL 3.0 (or any later version) and Business Source License 1.1 (with no Additional Use Grant). Refer to the corresponding LICENSE files for the full parameters of either license:

Dual licensing means that you can use the code under the terms of either license.

For example, if you are using this to test your rules functions and you do not want to be bound by the terms of the AGPL license (and thus be forced to release the source code of your rules), you can license the reng code under the BUSL 1.1 license.

On the other hand, if you wish to use reng in an internal-use only or open source service, then you can license reng under the terms of the AGPL 3.0 (or later) license. You can not use reng in this manner under the BUSL 1.1 license since it does not allow any additional use grant for production usage.

Refer to the License FAQ for more information.
