Graceful loc statistics for projects

There is great page with full statics for selected project.
E.g. http://stackalytics.com/?release=havana&metric=commits&project_type=All&module=rally

And on this page we have for LOCs only next: Total LOC: 12192

We could get much more information from LOCs:
1) Statistics by langues
2) Actual amount of LOC (without comments and empty lines)
3) Addition & Deletions

1 and 2 could be done with this utility: http://www.dwheeler.com/sloccount/
