#
# ==== How to use this script ====
#
# 1. Get recent commits added to RELEASE-NOTES:
#
# $ ./scripts/release-notes.pl
#
# 2. Edit RELEASE-NOTES and remove all entries that don't belong. Unused
# references below will be cleaned up in the next step. Make sure to move
# "changes" up to the changes section. All entries will by default be listed
# under bug-fixes as this script can't know where to put them.
#
# 3. Run the cleanup script and let it sort the entries and remove unused
# references from lines you removed in step (2):
#
# $ ./script/release-notes.pl cleanup
#
# 4. Reload RELEASE-NOTES and verify that things look okay. The cleanup
# procedure can and should be re-run when lines are removed or rephrased.
#
# 5. Run ./scripts/contributors.sh and update the contributor list of names
# The list can also be extended or edited manually.
#
# 6. Run ./scripts/delta and update the contributor count at the top, and
# double-check/update the other counters.
#
# 7. Commit the file using "RELEASE-NOTES: synced" as commit message.
