documentation is a documentation generator for API documentation. It uses a code scanner and supports structured documentation, so it follows in the tradition of tools like JavaDoc, Natural Docs, and JSDoc. There are other camps of documentation generation, like literate documentation, which is less structured and more focused on understanding internal code structure.
