# This script launches the checking of the availability of the files for 
# the sequences. 
#
# After checking if the script is already running the todolist is written.
# Then for each sequence the availability of the files (raw, cc, caco) is 
# checked by using the macro checkfilesavail.C 
# If this was successful, the status is inserted into the database using 
# the function setstatus.
