View source for OSX Grid Selector Script

On OSX environments, if you have multiple viewers and multiple grids to connect to, you can try the following AppleScript (one could do something similar with a shell script). Feel free to copy and modify for your own use.
<source lang="applescript">
 --
 --  This script selects a viewer and a grid for virtual worlds.
 --
 --
 -- Variables for the two supported viewers.  More may be added here.
 --
 set lindenViewer to "\"/Applications/SecondLife/Second Life.app/Contents/MacOS/Second Life\""
 
 set emeraldViewer to "\"/Applications/SecondLife/GreenLife Emerald Viewer.app/Contents/MacOS/GreenLife Emerald Viewer\""
 --
 -- Variables for options to select the specified grid.  Since the viewers
 -- are based on the 2nd life viewer, the options are the same for each
 -- viewer.  Also, connecting to the Second Life grid is the default option
 -- if no other options are provided.
 --
 -- Currently, four grids are supported.  More may be easily added.
