Re-generate license_finder reports in rake task or pre-commit hook

update_reports.sh

#!/bin/bash

HTML_REPORT=doc/dependencies.html

STATUS_REPORT=doc/dependencies.csv
checksum_before=$(md5 -q < $STATUS_REPORT)
checksum_after=$(license_finder report --format csv --columns approved name version licenses | tee $STATUS_REPORT | md5 -q)

# # Alternatively
# CHECKSUM_FILE=doc/dependencies_status.md5
# checksum_before=$(cat $CHECKSUM_FILE)
# checksum_after=$(license_finder report --format csv --columns approved name version licenses | md5 -q | tee $CHECKSUM_FILE)

if [ "$checksum_before" != "$checksum_after" ]
then
  license_finder report --format html > $HTML_REPORT;
  exit 1
fi

Maybe we should provide something like this as a supported rake task in, e.g., lib/license_finder/rake_tasks.rb?
