Inspired by Christian Trabold's session on ci.typo3.org at T3DD11 I spend some time gathering metrics data from all TYPO3 tags using phploc. (I did that before some time ago. Click here to see the old graphs).
Using Git and some lines of lines of bash scripts it was an easy task to checkout all tags, collect metrics data and merge it into a single csv file. Google Spreadsheet was a nice tool to create the graphs embedded. You'll find all data and you'll be able to browse through the graphs on the public spreadsheet aswell.
