st: xtprobit with clustered standard errors

["Brandice Canes-Wrone" <bcwrone@Princeton.EDU>]

I would like to cluster the standard errors using xtprobit.  I have
searched the STATA archives, databases of ado files, etc. and not found
anything helpful. Does anyone know of ado files that would facilitate
doing so, or have other suggestions? 
 
Thanks,
Brandice
