,----[ C-h v version-control RET ]
| version-control is a variable defined in `files.el'.
| Its value is nil
|
| Documentation:
| *Control use of version numbers for backup files.
| t means make numeric backup versions unconditionally.
| nil means make them for files that have some already.
| `never' means do not make them.
|
| You can customize this variable.
