.. _glossary: Glossary ======== .. glossary:: builder A class (inheriting from :class:`~sphinx.builder.Builder`) that takes parsed documents and performs an action on them. Normally, builders translate the documents to an output format, but it is also possible to use the builder builders that e.g. check for broken links in the documentation, or build coverage information. See :ref:`builders` for an overview over Sphinx' built-in builders. configuration directory The directory containing :file:`conf.py`. By default, this is the same as the :term:`source directory`, but can be set differently with the **-c** command-line option. description unit The basic building block of Sphinx documentation. Every "description directive" (e.g. :dir:`function` or :dir:`describe`) creates such a unit; and most units can be cross-referenced to. environment A structure where information about all documents under the root is saved, and used for cross-referencing. The environment is pickled after the parsing stage, so that successive runs only need to read and parse new and changed documents. source directory The directory which, including its subdirectories, contains all source files for one Sphinx project.
