Mailing list statistics and graphs

[Mike McCormack]

Fellow bean counters!

On the weekend I wrote a quick script to generate a graph of the number 
of patches committed to the Wine CVS per month.  The script and the 
graph it generates are attached.

Anybody think it would be interesting to have a page of similar graphs 
on WineHQ somewhere that's regenerated once a month?  Some ideas:

patches committed to winehq per month
patches sent to wine-patches per month
unique patch authors vs. months
lines of code committed per month
lines of code sent per month
...
