module jdk.javadoc
Defines the implementation of the system documentation tool and its command-line equivalent, javadoc.

## javadoc

This module provides the equivalent of command-line access to javadoc via the `ToolProvider` and `Tool` service provider interfaces (SPIs), and more flexible access via the `DocumentationTool` SPI.

Instances of the tools can be obtained by calling `ToolProvider.findFirst` or the service loader with the name `"javadoc"`.
