=== Description ===

[[Image(http://www.openxcap.org/chrome/site/SIMPLE-Winfo.png)]]

Watchers are defined as entities that request (i.e., subscribe to)
information about a resource, using the SIP event framework, RFC 3265. There
is fairly complex state associated with these subscriptions. This state
includes the identity of the subscriber, the state of the subscription, and
so on. The union of the state for all subscriptions to a particular resource
is called the watcher information for that resource. This state is dynamic,
changing as subscribers come and go. As a result, it is possible, and
indeed useful, to subscribe to the watcher information for a particular
resource. An important application of this is the ability for a user to find
out the set of subscribers to their presentity. This would allow the user to
provide an authorization decision for the subscription.

This script implements SUBSCRIBE for the watcher info event package and
manipulation of the pres-rules document that holds the presence policy of
the subscribing user.
