o Creating radar "loops"
  --------------------------
(1) add weather
(2) animate /mit/weather/RADAR/*.gif

    NOTE: This will display ALL the GIF images in the directory.  To
          save time and memory, you can display only the latest few
          images with something like:

	  animate `ls -1 /mit/weather/RADAR/*.gif | tail -6`

          This will display the last 6 images in the directory.

o Viewing the latest image
  ------------------------
(1) add weather
(2) add graphics
(3) xv /mit/weather/RADAR/latest

o Putting an image on your root background
  ----------------------------------------
(1) add weather
(2) add graphics
(3) xv -root -maxpect -quit /mit/weather/RADAR/latest
    [Note: If you wish to fill up the *entire* screen, you can type:
       xv -root -max -quit /mit/weather/RADAR/latest
    but the image will appear stretched vertically.]
