As we discussed in Chapter 14, Visual Source Safe is a tool used to version code and act as a code repository for team members.
One of the most useful features of Visual Source Safe is the capability to go back and check on earlier versions of a particular source code file. A new version is created every time you check in a file. You can get a line-by-line summary of changes, insertions, and deletions between any two versions, and you can restore a previous version if you want. Figure 16.5 shows a change report for a source file.
