# This script checks which files are on disk and updates the database 
# accordingly. It is not yet running automatically. 
# 
# It is checking the:
# - ccfiles
# - cacofiles 
#   this includes also the search for missing cacofiles:
#   Sometimes the DAQ aborts a run and starts itself a new one. In this 
#   cases the camera controll doesn't start a new file, as the command to 
#   start a new run was not sent by the central control. So the caco 
#   information is stored in the previous caco file, which has a 
#   different runnumber. To be able to merpp the information into the 
#   calibrated data file, the runnumber of the file containing the 
#   information has to be found.
#   In this script the search and inserting into the database is done 
#   using the macros findcacofiles.C and insertcacofile.C
# - rawfiles
# The update in the database is done using the macro resetallruns.C
#
