+ Enable or disable use of a revision control system.
+
+ If you use svn, the `source` directory is assumed to be
+ a [[Subversion]] working copy.
+
+ If you use git, the `source` directory is assumed to be a clone of the
+ [[git]] repository.
+
+ If you use tla, the `source` directory is assumed to be a tla import.
+
+ If you use mercurial, the `source` directory is assumed to be the
+ [[mercurial]] repository.
+
+ In [[CGI]] mode, with a revision control system enabled pages edited via
+ the web will be committed. Also, the [[RecentChanges]] link will be placed
+ on pages.
+
+ svn is enabled by default.
+
+* --svnrepo /svn/wiki
+
+ Specify the location of the svn repository for the wiki. This is required
+ for using --notify with [[subversion]].
+
+* --svnpath trunk
+
+ Specify the path inside your svn reporistory where the wiki is located.
+ This defaults to trunk; change it if your wiki is at some other location
+ inside the repository.
