# meant to run in a cronjob quite frequently, as often as there are
# files to send.
#
# This script expects the receiving side to have the following
# preceeding the ssh key entry in ~/.ssh/authorized_keys:
#   command="rsync --server -logDtpre.iLsfx --log-format=X --delete --delay-updates . /path/to/htdocs/fdroid/",no-port-forwarding,no-X11-forwarding,no-agent-forwarding,no-pty
