# This script is run on all of the systems where an automated
# X build will occur.  
#
# The main benefit of using this script is that if the type of build
# that needs to be done changes, (e.g. a clean build is needed 
# instead of an incremental build), then only this file needs to be 
# changed and none of the crontabs need to be changed.
