Contains the base classes that make up a doclet. Doclets that reuse the functionality provided by the toolkit should have the following characteristics:

- The main driver class should extend {@link com.sun.tools.doclets.internal.toolkit.AbstractDoclet}.
- The doclet configuration class should extend {@link com.sun.tools.doclets.internal.toolkit.Configuration}.
- The doclet should have a writer factory that implements {@link com.sun.tools.doclets.internal.toolkit.WriterFactory}. This class constructs writers that write doclet specific output.
- The doclet should have a taglet writer that extends {@link com.sun.tools.doclets.internal.toolkit.taglets.TagletWriter}. This writer determines how to output each given tag.
