# This script is linking the montecarlo files from the original structure
# to a structure from which the files can be processed more easily with the
# automatic analysis. 
# This script is not yet running automatically. 
#
# original structure:
# /montecarlo/camera/
#
# new structure: 
# /montecarlo/rawfiles/YYYY/MM/DD/file.root
# more explanation concerning the file structure can be found in the file
# /montecarlo/rawfiles/README.txt
#
# First the data files are linked and then in each new directory also the 
# pedestal and calibration file is linked.
