#
# This script handles the subsystem logfiles, which are copied every
# day automatically from /local/ on pc15 in La Palma to 
# /home/lapalma/transfer/ on coma in the datacenter in Wuerzburg
# The structure in this directory is: subsystem/date/logfile.*
# The logfiles are from CC (*.rep, CC*.dbg, CC*.rbk, CC*.rep, CC*.run,
# CC*.run.html), Cosy (cosy*.log, cosy*.rep, tpoint*.txt/starg*.txt) 
# AMC (AMC*.log, AMC*.info, AMC*.lut) and CaCo (dc*.txt) 
#
# the script performs the following steps:
# ----------------------------------------
# - filling the information from the *.rbk and *.run files into the DB
# using the macros filldotrbk.C and filldotrun.C
# - copying all logfiles to the correct directory:
# /subsystemdata/subsystem/YYYY/MM/DD/file.*
# - building the sequences for the standard analysis in the database
#   (for each day of which a file was copied) 
# - if a new catalogfile has been copied, it is installed as standard in the
#   setup directory /magic/datacenter/setup and the new lines are sent to 
#   the adresses specified in the script
# 
# -- to make sure that no file is copied twice there's a textfile
# (.processed), to which every file, that was processed, is added 
# .processed is copied to La Palma, so that it is possible to copy
# only new files
# -- to make sure that a file was copied completely before it is
# processed, a file with the checksum of all files is also copied from
# La Palma and the checksum is checked with this script for each file
# before processing it.
