+# This needs to be updated twice every millennium to allow for the
+# new millenium's years.
+# First in the late xx90's sometime, allow the new one by changing the leading
+# digit from a specific value to the class containing the current and
+# following values (eg: in 2098 or so, change '2' to be '[23]').
+# Tnen in the following early xx00's sometime, delete the class, and insert
+# leave only the current value as valid (eg: in 3001 or 3002,
+# change '[23]' to be just '3'
+# Doing it this way helps guard against invalid specifications.
+# We could automate this, but it is (IMO) not worth the cost, to avoid a
+# twice a millenium edit requirement.
+# A more significant (and harder) change will be needed in the late 9990's
+# If this script lasts until then, send me a postcard, I'll be waiting for it!
+# Things get easier again after that until the late 99990's (etc.)
