scripts and color

[James W. Meritt]

I use scripts to change various aspects of the window they are running in
on my Sun (using sunview).  Things like which icon, closing the window,
renaming the open window,... depending on what happens in the script.

What I want to do is change the color of the icon.  For instance, I would
like the color of the icon to match what stage of the script is currently
executing.

Any suggestions?
