One way they possibly could be derived is using something like the equivalent 
to `cvs annotate` to get lists of user commits for each file.  This would 
account for people that have spent 1.8 man years writing 4 lines of code.  
Maybe his code got replaced or committed by someone else.  Only the last 
modifications to a line would show up.

Really, without going through each and every line of EVERY commit, it is 
impossible to gauge how much code each person has spent.  And people write 
code at different speeds too.
