Not sure why I'm full of fail when it comes to Git, but here you have
the latest branch with some new stuff:

	http://github.com/janl/couchdb/tree/old-stats-new

News:

  - Added GET /_stats view (thanks Paul Davis and Martin Scholl for  
help).
  - Added Martin Scholl's implementation of less complex average &  
stddev
    calculation.
  - Add more tests, heh.
  - Messed up stats-new branch.


Todo:

  - Integration with build process.
  - Conditionally compile eunit source on `make test` not for regular  
`make`.
  - Merge with old `make test` code.
  - Add absolute value counter for things like request time.
   - In the process we'll remove the little clunky DifferencesList  
stuff and
     make all aggregators use absolute values.
  - Add float precision to aggregate values.
  - Move to ASF subversion branch.

If you could help us prioritize the Todo list, we're happy to follow  
your
suggestions. Thanks!

Cheers
Jan
