Entitlements
Before a The Pixel Farm product, such as PFClean or PFTrack, can run on a host machine, an entitlement needs to be assigned to that host.
Each entitlement can only be assigned to one host at any time, and each host can only have one entitlement for each product assigned to it at any time. For example, a machine can have one PFClean and one PFTrack entitlement assigned to it, but it cannot have two PFTrack entitlements assigned at the same time.
Entitlements can be assigned to a host, or released from a host, using PFManager.
