# Usage : update-base base_name [ images | src ]

# This shell script executes scp and ssh commands with the remote server
# This requires (?) that you have installed a pair of private/public keys on both machines
# See "how to create a key pair" on teh web

# An alternative to key pairs is to send password information with the commands
# To do this, add ":password" after username in each occurence of USER@SERVER 
# Be aware that password is sent in cleartext !!
