Sphinx provides utility classes and functions to develop extensions.
These base classes are useful to allow your extensions to obtain Sphinx components (e.g. :class:`.Config`, :class:`.BuildEnvironment` and so on) easily.
Note
The subclasses of them might not work with bare docutils because they are strongly coupled with Sphinx.
