[Douglas Kosovic]

Hi Akhila,

If you want to set vic's geometry you can use a Tk geometry string with 
something like:

vic -X geometry=1000x500+300-400 234.5.6.7/16000

i.e. 1000 pixels wide by 500 pixels tall, with the left edge 300 pixels 
from the left of the screen, and the bottom edge 400 pixels up from the 
base of the screen.

Set the number of tiled columns to 2 with "-X tile=2", etc.

It's easier to understand what you modified by seeing the output of 
issuing the following on the command-line in vic's folder:
  svn diff
