+ * winjump.c: support for Windows 7 jump lists.
+ *
+ * The Windows 7 jumplist is a customizable list defined by the
+ * application. It is persistent across application restarts: the OS
+ * maintains the list when the app is not running. The list is shown
+ * when the user right-clicks on the taskbar button of a running app
+ * or a pinned non-running application. We use the jumplist to
+ * maintain a list of recently started saved sessions, started either
+ * by doubleclicking on a saved session, or with the command line
+ * "-load" parameter.
+ *
+ * Since the jumplist is write-only: it can only be replaced and the
+ * current list cannot be read, we must maintain the contents of the
+ * list persistantly in the registry. The file winstore.h contains
+ * functions to directly manipulate these registry entries. This file
+ * contains higher level functions to manipulate the jumplist.
