# Generate notification files based on current and previous artifacts, which

#
# Notes:
# 1. Current artifacts are in $top_artifacts. All files from $top_artifacts
# are accessible read-only, and round-robin-notify.sh writes its files
# into $top_artifacts/notify/.
# 2. Files in "numbered" directories NN-* should not be used, since they
# will be eventually removed.
# 3. Previous artifacts are in base-artifacts/, which is a git repository.
# All files from base-artifacts/ are accessible read-only.
# 4. Round-robin-notify.sh can assume that files in $top_artifacts/ and
# in base-artifacts/ have been generated by the latest version of scripts.
# Developers will run round-robin-rewrite.sh when format of files changes
# to bring "history" results up-to-date with what current scripts expect.
# 5. Round-robin-notify.sh can assume that check_regression() step was run
# just before invocation of round-robin-notify.sh.
