+// A DownloadItem normally goes through the following states:
+//      * Created (when download starts)
+//      * Made visible to consumers (e.g. Javascript) after the
+//        destination file has been determined.
+//      * Entered into the history database.
+//      * Made visible in the download shelf.
+//      * All data is received.  Note that the actual data download occurs
+//        in parallel with the above steps, but until those steps are
+//        complete, completion of the data download will be ignored.
+//      * Download file is renamed to its final name, and possibly
+//        auto-opened.
+// TODO(rdsmith): This progress should be reflected in
+// DownloadItem::DownloadState and a state transition table/state diagram.
+//
+// TODO(rdsmith): This description should be updated to reflect the cancel
+// pathways.
