Automating snapshots

I have a couple of VM machines in my environment that I want to keep a history of 5 snapshots each. Basically 5 days of snapshots. How can I go about doing this?

Create a snapshot for each day then on day 6 it will delete the snapshot from day 1 and so on.

I am on ESX 3.5U3 and VC 2.5 U4

Thanks for the help.
