# This script adds contributions of files/directories in backend to volume
# size.
# It can also be used to debug by passing dir as first argument, in which case
# it will just add contributions from immediate children of a directory and
# displays only if added contributions from immediate children is different
# from size stored in directory.
# For Eg., find <backend-directory> -type d -exec ./contri-add.sh dir \{} \;
# will list all the directories which have descrepancies in their
# size/contributions.
