+/**
+ * nsIProgressEventSink
+ *
+ * This interface is used to asynchronously convey channel status and progress
+ * information that is generally not critical to the processing of the channel.
+ * The information is intended to be displayed to the user in some meaningful
+ * way.
+ *
+ * An implementation of this interface can be passed to a channel via the
+ * channel's notificationCallbacks attribute.  See nsIChannel for more info.
+ *
+ * The channel will begin passing notifications to the progress event sink
+ * after its asyncOpen method has been called.  Notifications will cease once
+ * the channel calls its listener's onStopRequest method or once the channel
+ * is canceled (via nsIRequest::cancel).
+ *
+ * NOTE: This interface is actually not specific to channels and may be used
+ * with other implementations of nsIRequest.
