# This script launches the building of sequences for all days for which 
# this step is needed. 
#
# 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
