# uaconvert 
# This shell will merge a new release ua file (e.g., Office)
# with an old file by keeping all of the new release file
# and appending the objects (i.e., Name=) that were found
# in the old file but are not in the new release file
#
# it requires 2 parameters, the oldfile and then the newfile names
#
# an optional third parameter forces "debug"mode which reports progress
# to the standard output and does not erase the /tmp files
