+@node VC-Aware Project Backend
+This backend is part of Emacs and is enabled by default.  (Other
+backends may need installation of add-on packages and their proper
+configuration.)
+
+It determines the contents of the project based on the VCS repository's
+configuration (if any), excluding the ``ignored'' files from the output.
+
+It has some performance optimizations for listing the files with some of
+the popular VCS systems (currently Git and Mercurial).

+@defopt project-vc-ignores
+Using this variable you can add more ignore patterns to the project, to
