Quieten this cron script

#!/usr/bin/env ruby

# Create authormap files for hg repos based on the changeset & project
# member info available to Redmine.
#
# We have a set of hg repos in a given directory:
#
# /var/hg/repo_1
# /var/hg/repo_2
# /var/hg/repo_3
#
# and we want to produce authormap files in another directory:
#
# /var/repo-export/authormap/authormap_repo_1
# /var/repo-export/authormap/authormap_repo_2
# /var/repo-export/authormap/authormap_repo_3
#
# This script does that, if given the two directory names as arguments
# to the -s and -o options. In the above example:
#
# ./script/rails runner -e production extra/soundsoftware/create-repo-authormaps.rb -s /var/hg -o /var/repo-export/authormap
#
# Note that this script will overwrite any existing authormap
# files. (That's why the output files are given an authormap_ prefix,
# so we're less likely to clobber something else if the user gets the
# arguments wrong.)
