push_update_to_all_clients.sh

#!/bin/bash

# Running this script will cause the updatesite directory checked by clients
# to be updated with the current files in the trunk directory. It will not
# automatically update trunk, so if you have a specfic revision checked out,
# that's what will be used. See constants below.
#
# You will need sudo privileges to use this. Don't run this as sudo, it will
# invoke sudo when it needs it.
#
# Usage: ./push_update_to_all_clients.sh
