#	SaveNewFiles [dir] [timefile]
#
# This script searches out all the new files under the given directory, and 
# makes a shadow copy in the /save/`hostname` directory.  By "new" is meant 
# any file newer than timefile, which defaults to /save/`hostname`/.lastsave; 
# if it doesn't exist, it is created (and is the start time for future saves).  
# 
# Saving is done by making a shadow copy in the /save/`hostname` directory.  
# It is suggested that you use this script once a day, or whenever you have 
# reached a critical point and would like reassurance that your files are 
# backed up.  The /save directory will be backed up to tape periodically, 
# and files older than some limit will be deleted from /save.
