"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, like 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."
