1. Extend table at top of https://docs.oracle.com/en/java/javase/20/jshell/scripts.htm Chapter 7 "Scripts" with a new row:

TOOLING | Defines JShell methods accessing JDK Tools like `javac`, `javadoc`, and `javap` using their command-line interface.

2. Add a new subsection for `TOOLING` script

See JDK-8315230

Since version 21 the JShell tool for interactive exploration of Java code has been enhanced with a new predefined script, `TOOLING`.

The `TOOLING` script provides direct access to the JDK's command line tools, such as `javac`, `javadoc`, and `javap`, from within JShell. Similar to the existing predefined `DEFAULT` and `PRINTING` scripts, the `TOOLING` script can be loaded when JShell starts by running: `jshell TOOLING`. Alternatively, it can be loaded within a JShell session by using: `/open TOOLING`.

With the `TOOLING` script loaded, observable tool services implementing the `java.util.spi.ToolProvider` interface can be run by passing a name and an array of arguments to the `run(String name, String... args)` method. Call `tools()` to print a sorted list of names for all runnable tools. For example:

```text
jshell> tools()

jar
javac
javadoc
javap
jdeps
jlink
jmod
jpackage

jshell> run("javac", "--version")
```

For well-known JDK tools, the `TOOLING` script also defines convenient methods, such as `javac(String... args) { run("javac", args); }`, delegating to the `run` method. This shortens the last call of the previous example to:

```text
jshell> javac("--version")
```

In addition, the `javap` tool that disassembles class files is also represented by a `javap` method that takes a class literal. JShell users can have the `javap` tool disassemble and print an overview of a existing or newly created type without leaving the session:

```text
jshell> javap(java.lang.Runnable.class)

jshell> interface Empty {}
jshell> javap(Empty.class)
```
