+# A collator can be set with "@ root" or "@ locale language-tag",
+# for example "@ locale de-u-co-phonebk".
+# An old-style locale ID can also be used, for example "@ locale de@collation=phonebook".
+
+# A collator can be built with "@ rules".
+# An "@ rules" line is followed by one or more lines with the tailoring rules.

+# A collator can be modified with "% attribute=value".

+# "* compare" tests the order (= or <) of the following strings.
+# The relation can be "=" or "<" (the level of the difference is not specified)
