# The goal in this script is to take a large Git repostiory and find a
# simple list of all commit ids that match certain criteria, specifically,
# either an Author: field or
# either an Author: field or if they are mentioned in the patch.
# The recommended ATTRIBUTING_LOG_MESSAGE_REGEX is something like this:
# The initial implementation looks
# (Submitted\s+by|original\s+patch|patch\s+(from|by)|originally\s+(from|by)).*
# The idea is this: It's quite common in older times for someone to commit
# on behalf of someone else, where the Author: field reads a particular
# author, but the log message says that someone else wrote it. We're
# looking for a specific author, but we want to eliminate those commits
# where that Author attributed them to someone else, and include those
# commits where someone else indicated that our sought author actually wrote
# the patch.
