Gradle can be invoked in different ways:
* Through the [Gradle Wrapper](https://docs.gradle.org/8.8/userguide/gradle_wrapper.html)
  * It currently requires a JVM and will download the Gradle distribution if it is not already present.
* A Gradle version installed on the system
  * This starts the [Gradle Launcher](https://blog.gradle.org/how-gradle-works-1#local-gradle-distribution-in-cli), which itself requires a JVM

`doc/next/*stdlib/*minor`.
The files should be in the subdirectory for the package with the new
API, and should be named after the issue number of the API proposal.
For example, if the directory `6-stdlib/99-minor` is present,
then an `api/next` file with the line

    pkg net/http, function F #12345

should have a corresponding file named `doc/next/6-stdlib/99-minor/net/http/12345.md`.
