The `make generate-summary` target produces a handy tabular summary of all of the modules in a JDK build into `$BUILD/images/gengraphs/module-summary.html`. Several JDK modules (e.g., `java.desktop` and `jdk.internal.vm.compiler`) include many providers for a particular service, and the providers are all listed in a single line, resulting in a very wide HTML page that’s difficult to read even on a large screen.
