   Preview Tool (invoked on the command line as "previewtool") displays information about VSNs waiting to be mounted.
   To start Preview Tool, click once on its icon.  The previewtool command must be in your path for the tool to be successfully launched.
   Preview Tool allows you to select the type of information you want to see.  This is controlled by the "Display" menu, located in the upper left corner, and by the "Media" menu, located in the upper middle.  Each menu appears when you click the mouse "menu" button on the abbreviated menu button for that menu.
   The "Display" menu allows you to choose to see all VSNs waiting for mount, only those waiting for a manual mount, only those waiting for a robot to mount them, or only those associated with a specific robot.  When "specific robot" is selected from the "Display" menu, the "Robot" abbreviated menu button appears below the "Display" abbreviated menu button, allowing you to select a specific robot from the list of configured robots; use the mouse "menu" button to do this, just as you selected a format.  The "Media" menu allows you to view pending mounts for a specific media type.  Selecting "all" in both the "Display" and "Media" menus displays all pending mounts.
   Preview Tool provides a button at the bottom of its window for clearing an individual mount request.  To clean a request, select that request in the display and then click once on the "Clear Request" button.
   The display can be updated by clicking on the "Update" button, located in the upper right of the window.  The display will automatically update when you have specified a refresh rate (in the upper right corner) greater than zero and refresh is turned on.  Refresh is turned on when a checkmark appears in the box immediately to the left of "refresh"; clicking on this box toggles automatic refresh on and off; it is on by default.
