...VIB is Ideal in environments where you have multiple users logging into a UNIX system and you wish to keep track of whom is modifying files.
For example, VIB could be 'aliased' in all new user shell accounts, so that when they edit a file using "vi", a log entry will be generated, and a backup copy of the file with their username will also be notated.
The goal of VIB is to assist with tracking who modified what file, when on a UNIX/Linux systsm.
