2. The ability to tr ack changes pr omotes accountability and makesit easier to find the r ight per son to solve problems in the

mater ials maintained.3. A list of exact changes made can be generated quickly and

easily, making it easier to advise user s of the infor mation on how it has changed f r om ver sion to ver sion.

4. It is easy to 'roll back' to an earlier version of the infor mation,if a ser ious mistake was made dur ing a change.

Br anch: A branch is a side-line of development created to make lar ger , exper imental or disrupting wor k without annoying user s of the

trunk ver sion. Also, br anches can be used to create developmentlines for multiple ver sions of the same pr oduct, like having a place tobackpor t bugfixes into a stable release.

Tags: Finally, tags are mar ker s to highlight notable revisions in the

histor y of the repositor y, usually things like "this was released as1.0".
