+  "The major mode used in VC directory buffers.  It works like Dired,
+but lists only files under version control, with the current VC state of 
+each file being indicated in the place of the file's link count, owner, 
+group and size.  Subdirectories are also listed, and you may insert them 
+into the buffer as desired, as in Dired.
+  All Dired commands operate normally, with the exception of `v', which
+is redefined as the version control prefix, so that you can type 
+`vl', `v=' etc. to invoke `vc-print-log', `vc-diff', and the like on
+the file named in the current Dired buffer line.  `vv' invokes
+`vc-next-action' on this file, or on all files currently marked.
+There is a special command, `*l', to mark all files currently locked.
