# function zfcget {

# 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,
# and that perl is version 5 with the standard library.
# See the function zfrtime for more gory details.
