-# the general purpose logging machine
-#
-# This module is designed to allow you to log stuff in SMG format
-#
-# The idea is that you give it a prefix which is a directory and then 
-# the system will log stuff to a directory structure which looks like:-
-#
-# ./logs/<prefix>/yyyy/mmdd.[log|<optional suffix]
-#   
-# Routines are provided to read these files in and to append to them
