In all probability the command in question is this one:
http://siteresources.worldbank.org/INTPAH/Resources/Publications/459843-
1195594469249/dominance.ado

It was already mentioned in the list earlier:
http://www.stata.com/statalist/archive/2008-06/msg00296.html

The description of syntax and examples can be found e.g. here:
