/**
 * The user doclet must implement this interface, as described in the
 * <a href="package-summary.html#package.description">package description</a>.
 * Each implementation of a Doclet must provide a public no-argument constructor
 * to be used by tools to instantiate the doclet. The tool infrastructure will
 * interact with classes implementing this interface as follows:
 * <ol>
 * <li> The tool will create an instance of a doclet using the no-arg constructor
 *  of the doclet class.
 * <li> Next, the tool calls the {@link #init init} method with an appropriate locale
 *  and reporter.
 * <li> Afterwards, the tool calls {@link #getSupportedOptions getSupportedOptions},
 * and {@link #getSupportedSourceVersion getSupportedSourceVersion}.
 * These methods are only called once.
 * <li> As appropriate, the tool calls the {@link #run run} method on the doclet
 * object, giving it a DocletEnvironment object, from which the doclet can determine
 * the elements to be included in the documentation.
 * </ol>
 * <p>
 * If a doclet object is created and used without the above protocol being followed,
 * then the doclet's behavior is not defined by this interface specification.
 * <p> To start the doclet, pass {@code -doclet} followed by the fully-qualified
 * name of the entry point class (i.e. the implementation of this interface) on
 * the javadoc tool command line.
