MediaWiki SVN Statistics

I was wondering how many of the SVN committers are active and how often, so I made a PERL script to read in all the commits (svn-report.pl) and another (svn-results.pl) to format the results into monthly totals as shown below. The core commits are those changes made to the MediaWiki code-base (the phase3 branch) rather than those made to other areas of the repository such as extension code.
