+testdata/zoneinfo contains time-zone data files that may be used with CCTZ.
+Install them in a location referenced by the ${TZDIR} environment variable.
+Symbolic and hard links have been eliminated for portability.
+
+On Linux systems the distribution's versions of these files can probably
+already be found in the default ${TZDIR} location, /usr/share/zoneinfo.
+
+New versions can be generated using the following shell script.
+
+  #!/bin/sh -
+  set -e
+  DESTDIR=$(mktemp -d)
+  trap "rm -fr ${DESTDIR}" 0 2 15
+  (
+    cd ${DESTDIR}
