Thanks for the reply David. I think 'tagged directory' wasn't the appropriate phrase here. In Subversion like systems branches and tags are same, i.e., both are created using 'svn copy'. Branches are generally created for separate line of development and tags for releasing software. So developers follow convention of not checking in anything into tags. Otherwise they are same. I know that creating branches/tags doesn't involve copying files into new directory in case of git. It will act as a pointer and make note of changes thereafter. What I am not sure is difference between branches and tags. Is it left to developer to follow subversion like convention or git provides some mechanism to 'lock' tags? - CS.
