All I can say is every time I've tried this it's been a nightmare, and
when you say "apart from CVS imported revisions" my hair stands on
end. And the GCC history is two and a half times the size of the next
largest repo I've tried this on.
If you want to try writing the program to do this data analysis, go right
ahead. Somebody would have to pay me real money to try.
