# function zfcget {

# Continuation get of files from remote server.
|
|
# 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,
|
|
# and that perl is version 5 with the standard library.
|
|
# See the function zfrtime for more gory details.
