The old -adjust- command has been superceded by -margins-.  Given 
that -adjust- has a generate option, I wonder why -margins- does not?
Personally, I wish -adjust- had been updated for Stata 11.  -margins- 
may be able to do most of the same things, but the command can be a 
little overwhelming -- adjust was pretty straightfoward.
