Built jars for Forgelin are mixed-license:

• Forgelin (io.drakon.forgelin) is under the MIT License (see GitHub)
• Kotlin (kotlin) is under the Apache 2 License (see the Jetbrains Kotlin website)

Only the MIT License applies to using Forgelin code in repackaged projects - the Apache 2 component is dependant on whether Kotlin is packed in the Jar.
