# This script is NOT part of production builds. It is an assist in "republishing" 
# results, such as if there is a connection problem, or a script needs to be fixed to 
# publish correctly. Even if this script "works", it does not change the files on 
# download server, they much be "re-synch'd" manually. 

# This script is only and "assist" to republish. It is not fool proof (and not well tested) 
# and its exact use depends on what ever the problem was.
