+# After checking, if the script is already running, the todolist is 
+# written by using the macro getdolist.C
+# Then the sequences are built for each date in the todolist using the 
+# macro buildsequenceentries.C
+# If this was successful, the status is inserted into the database using 
+# the macro setstatus.C
