12.7.5.1: Registering a File for Version Control

You can put any file under version control by simply visiting it, and then typing C-x v i (vc-register).

To register the file, Emacs must choose which version control system to use for it. You can specify your choice explicitly by setting vc-default-back-end to RCS, CVS or SCCS. Otherwise, if there is a subdirectory named `RCS', `SCCS', or `CVS', Emacs uses the corresponding version control system. In the absence of any specification, the default choice is RCS if RCS is installed, otherwise SCCS.

If locking is in use, C-x v i leaves the file unlocked and read-only. Type C-x C-q if you wish to start editing it. After registering a file with CVS, you must subsequently commit the initial version by typing C-x C-q.

The initial version number for a newly registered file is 1.1, by default. You can specify a different default by setting the variable vc-default-init-version, or you can give C-x v i a numeric argument; then it reads the initial version number for this particular file using the minibuffer.

If vc-initial-comment is non-nil, 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 (see Log Buffer).
