Suppressing Staves

[Aaron Dalton]

I've done a search for ways to suppress staves in an orchestral excerpt 
should that staff contain nothing but rests for the duration of the 
current system.  The only thing I have found is a reference to:

\translator { \RemoveEmptyStaffContext }

for which I can find no documentation anywhere.  Is this the command I'm 
looking for?  If so, how does it work?  If not, how should I accomplish 
my design?

Thanks as always for your time and assistance.
