CART -- usually I think regarded as an abbreviation of 
Classication and Regression Trees, after the monograph 
by Breiman, Friedman, Olshen and Stone -- has been requested 
several times as an addition to official Stata, including 
at the NASUG meeting in Boston on March 17. The Stata 
Corp response is in essence "We'll think about it".
