StatCVS is an open source program written in Java that generates graphical reports about CVS modules. It reveals, for example, which developer has made the most check-ins to the repository, and plots the development of the lines of code (LOC) of the entire module and individual folders over time.
StatCVS uses JFreeChart to generate charts. It is licensed under the GNU General Public License.
StatSVN is an extension to StatCVS that generates the same reports but for the activity of a Subversion repository.
