     Subversion Source
     -----------------
 
-    Subversion source detects classical trunk/branches/tags layouts.
-    By default, the supplied "svn://repo/path/" source URL is
-    converted as a single branch. If "svn://repo/path/trunk" exists it
-    replaces the default branch. If "svn://repo/path/branches" exists,
-    its subdirectories are listed as possible branches. If
-    "svn://repo/path/tags" exists, it is looked for tags referencing
-    converted branches. Default "trunk", "branches" and "tags" values
-    can be overridden with following options. Set them to paths
-    relative to the source URL, or leave them blank to disable auto
-    detection.
