+#
+# After checking, if the script is already running, the todolist is

+# 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 macro setstatus.C
