# Use rsync over ssh to copy files. This particular invocation of
# rsync makes a backup of the file before overwriting it. For example,
# if cdist overwrites /etc/passwd then you'll end up with the old copy
# at /etc/passwd~cdist.
#
# Usage:
# cdist config --remote-copy /path/to/this/script target_host
#
# For rsync to do the right thing, the source has to end with "/" if it is
# a directory. The below preprocessor loop takes care of that.
# second last argument is the source
