Hello Glenn and all,
The solution given below is what I wanted my build.xml file to do. I
appologize if I had not been clear with my question earlier.
With all the replies I received, I now understand how the 'unless' attribute
works and have a better understanding of how to use the available and condition
tags as well.
Thank you all very much again for your time and help!
