# Lists resource keys with no caller in the C# sources.
#
# Written for the v1.12.0 cleanup and kept, because the count only stays
# honest if it can be re-measured: every block of that cycle both revived
# orphans and created new ones, so a list taken once is wrong by the next
# commit.
#
# Reports rather than deletes. A key without a caller is a question -- was the
# feature removed on purpose, or did it only lose its button? -- and the answer
# is in the git history, not in this script.
