+# HOW TO UPDATE THE ZONEINFO DATA
+#
+# In a clean directory, unpack the distribution archive and run:
+#
+# $ cvs -d :ext:ncvs.freebsd.org:/home/ncvs import -b 1.1.2 \
+# src/share/zoneinfo ADO tzdataYYYYt
+#
+# where YYYYt is the year and the version of the distribution, for
+# example 2004h.
+#
+# Then go to the checked out source, and merge the changes from the
+# previous tag to the new tag in the HEAD:
+#
+# $ cd ../src/share/zoneinfo
+# $ cvs update -jtzdataYYYYp -j tzdataYYYYt
+#
+# Update it again:
+#
+# $ cvs update
+#
+# And push it back into CVS:
+#
+# $ cvs ci
+#
