# This script launches the checking of the availability of the files for 
# the datasets. 
#
# After checking if the script is already running the todolist is written.
# Then for each dataset the sequences are extracted from the datasetfile 
# and for each sequence the availability of the star files checked by using 
# the macro checkstardone.C 
# If this was successful, the status is inserted into the database using 
# the function setstatus.
