[ALPS-users] INHOMOGENEOUS and DISORDER tags?

Hi, In one of the presentations that are available on the ALPS webpage, the <INHOMOGENEOUS> tag is mentioned. As I was going through the doc folder on the ALPS installion I see the mention of a <DISORDER> tag as well. However, besides these instances I cannot seem to find any information on how to actually use these tags when defining different lattices e.g. syntax and then how to implement site dependent hamiltonians. I was wondering if there are any examples about how to use these tags? Thanks very much.
