+# For each file, if it's shorter here, try to get the remainder from
+# over there.  This requires the server to support the REST command
+# in the way many do but RFC959 doesn't specify.
+# Options:
+#   -G   don't to remote globbing, else do
+#   -t   update the local file times to the same time as the remote.
+#        Currently this only works if you have the `perl' command,

+#        See the function zfrtime for more gory details.
