# File:    find_duplicate_events.fcl
# Purpose: Prints a list of the duplicate events in the input.
# Author:  Gianluca Petrillo (petrillo@slac.stanford.edu)
# Date:    May 5, 2021
#
# This configuration requires to read the content of the input files,
# and it prints a summary of duplicate events into a
# `DuplicateEventSummary.log` file.
# Note that if the production file naming convention allows, it may be
# much faster to detect duplicate files from that naming convention.
#
# Example of usage:
#     
#     lar -c find_duplicate_events.fcl -S input.list
#     
# will report in `DuplicateEventSummary.log` (and on screen)
# about all the duplicate events in the files listed in `input.list`.
