R help - Oct 2009 - reference for mahalanobis {stats}

The help on mahalanobis {stats} does not include any reference. I'm
interested in understand why Mahalanobis is defined in its current way
and how to use it. Could somebody point me a good book on this? I have
looked through a few books, but they all give very light explanation
on it.

The wikipedia page looks pretty good ... the "Intuitive Explanation"  
section should help:

http://en.wikipedia.org/wiki/Mahalanobis_distance

Googling also provides many more explanations:
