Tobias Schlitt, on the heels of the "PHP Eats Rails for Breakfast" posting on Ohloh has helped Sebastian Bergmann get the eZ components project entered into their database for some tracking with some interesting results.

eZ components consists of 171,025 lines of code (including markup and code itself). If you subtract the XML, eZ components consist of 96,424 lines of pure PHP code (no docs included, if I got it correcltly), which is rather much in my eyes.

He gives other stats for the component framework including a price estimate for manhours put into the project and how much, on a per-developer basis, has been contributed to each (including things like a code to documentation ratio and total lines of code contributed).
