-@subsubsection Registering a File for Version Control
-
-@kindex C-x v i
-@findex vc-register
- You can put any file under version control by simply visiting it, and
-then typing @w{@kbd{C-x v i}} (@code{vc-register}).
-
-@table @kbd
-@item C-x v i
-Register the visited file for version control.
-@end table
-
- To register the file, Emacs must choose which version control system
-to use for it. If the file's directory already contains files
-registered in a version control system, Emacs uses that system. If
-there is more than one system in use for a directory, Emacs uses the
-one that appears first in @code{vc-handled-backends}
-@iftex
-(@pxref{Customizing VC,,,emacs-xtra, Specialized Emacs Features}).
-@end iftex
-@ifnottex
-(@pxref{Customizing VC}).
-@end ifnottex
-On the other hand, if there are no files already registered, Emacs uses
-the first system from @code{vc-handled-backends} that could register
-the file (for example, you cannot register a file under CVS if its
-directory is not already part of a CVS tree); with the default value
-of @code{vc-handled-backends}, this means that Emacs uses RCS in this
-situation.
-
- If locking is in use, @kbd{C-x v i} leaves the file unlocked and
-read-only. Type @kbd{C-x v v} if you wish to start editing it. After
-registering a file with CVS, you must subsequently commit the initial
-revision by typing @kbd{C-x v v}. Until you do that, the revision ID
-appears as @samp{@@@@} in the mode line.
-
-@vindex vc-default-init-revision
-@cindex initial revision ID to register
- The default initial revision ID for a newly registered file
-varies by what VCS you are using; normally it will be 1.1 on VCSes
-that use dot-pair revision IDs and 1 on VCSes that use monotonic IDs.
-You can specify a different default by setting the variable
-@code{vc-default-init-revision}, or you can give @kbd{C-x v i} a
-numeric argument; then it reads the initial revision ID for this
-particular file using the minibuffer.
-
-@vindex vc-initial-comment
- If @code{vc-initial-comment} is non-@code{nil}, @kbd{C-x v i} reads an
-initial comment to describe the purpose of this source file. Reading
-the initial comment works like reading a log entry (@pxref{Log Buffer}).
