+# Notes on Lua:
+# The backslash in strings (like "\n" newline) needs to be doubled
+# because we are inside rpm macro. Single backslashes before most chars
+# disappear (removed by rpm's parser), so "\n" turns into just "n".
+# In string.gsub patterns, unlike regexps, backslash has no special meaning.
+# It can't escape . and such. (Use one-character set [.] to represent
+# literal period, or lua's percent escape: %.)
+# Pipe (|) has no special meaning too.
