*: ''These sub-directories(Task1, Task2,...) are called branches of trunk. When the word '''branch''' is used as a verb, it means copying the whole '''trunk''' into a sub-directory, either in '''branches''' or '''tags'''.

* '''tags''' is the directory that holds '''copies''' of successful stages of '''trunk''' throughout development. (''Also called as '''Milestones''''')

* '''tags''' are never modified or edited. ''You may branch a directory of tag into branches under a workspace and then modify the branch and apply the changes back to trunk, but you should never change the contents of a tag''
