+/**
+ * nsIWindowWatcher is the keeper of Gecko/DOM Windows. It maintains
+ * a list of open top-level windows, and allows some operations on them.
+
+ * Usage notes:
+
+ * This component has an |activeWindow| property. Clients may expect
+ * this property to be always current, so to properly integrate this component
+ * the application will need to keep it current by setting the property
+ * as the active window changes.
+ * This component should not keep a (XPCOM) reference to any windows;
+ * the implementation will claim no ownership. Windows must notify
+ * this component when they are created or destroyed, so only a weak
+ * reference is kept. Note that there is no interface for such notifications
+ * (not a public one, anyway). This is taken care of both in Mozilla and
+ * by common embedding code. Embedding clients need do nothing special
+ * about that requirement.
+ * This component must be initialized at application startup by calling
+ * setWindowCreator.
