#
# 2019-12-16: scripts created after some changes applied to this skeleton:
# https://superuser.com/questions/297342/rsync-files-newer-than-1-week/297343
# Note: it rsyncs files from REMOTE target dir into local dir. So you need to
# call this script from the dir where you want to put files into.
#
# 2020-08-17: added -P option to rsync to show the progress bar during the
# transfer.
