# This script processes the output from ps-lsof which is a two column list, where
# the 1st and 2nd columns must be delimited by a space. The first column of the
# input is the process name.  The second column is the file. It then compares
# the filename with the file at $PACKAGELIST which is a two column file delimited
# by spaces, the first column is the name of the package and the second is the
# filename which belongs to the package.
