This doclet-independent package has a set of classes and
interfaces that are the building blocks for doclets. They
define the basic structure of doclets and make doclet
writing much easier because they provide the content generation
code to be shared among different doclets. Builders only provide
the structure and content of API documentation.
They will not provide any style markup.
This code is not part of an API.
It is implementation that is subject to change.
Do not use it as an API.
