Remember, not all contributors are committers.  It might be worth also
looking at names in the SVN commit memo for "Patch by:"

Also, watch out for how branch -> trunk integration is tracked.  For
example, if a developer does months of work in a branch and then
integrates it into the trunk, how is that recorded in your script?  I
saw one analysis of our commits that took months of work on the
Sidepanel and called it all a single commit when it was integrated!
