     Directives are functions that users of your plug-in can use in their build file in order to configure your plug-in. These can be any kind of Kotlin function but in the interest of preserving a clean syntax in the build file, it's recommended to use the type safe builder pattern, <a href="https://kotlinlang.org/docs/reference/type-safe-builders.html">as described here</a>.
