# In this case, it runs a script to use rsync to copy files from the directory /etc/distrib on the server (baskerville, for now) to /etc/distrib on the client. While rsync can run over ssh, we first need to check that the ssh config files are up-to-date. So the first part of the script handles copying the files in /etc/distrib/ssh, and then the script copies everything else in /etc/distrib over ssh: 
# 
# Script for pulling system administration files from a server via anonymous
# rsync over ssh

RSYNC=/usr/local/bin/rsync
RSYNCPATH=/usr/local/bin/rsync
SERVER=baskerville

SSHPATH=/usr/local/bin/ssh

#
# First get the ssh config and known hosts files

	umask 022; mkdir -p $DIR/ssh 

	$RSYNC --archive --rsync-path $RSYNCPATH --timeout 30 $SERVER::ssh $DIR/ssh
