# true ::
|

# Take the last-modified time of the current file on disk, and only download
|
|
# if the server has a file that was modified later. Download unconditionally

# if we don't have the file yet. Default.

|
|
# nil ::
|
|
# Only download the file if it doesn't exist yet.
|
|
# false ::
|
|
# always download url regardless of whether we already have a file,
|
|
# and regardless of modification times. (This is essentially just a waste of
|
|
# network resources, except in the case that the file we have is somehow damaged.

# Please note that using this recurringly might create or be seen as a
