# This script is launching the calibration of sequences. 
# 
# As callisto takes some time, only one sequence is processed at once. 
# First the script gets a sequence number from the database, for which 
# the calibration has to be done (function gettodo). After setting the 
# status in the database (set fStartTime to know, that the sequence is 
# already being processed), the sequence is calibrated and the merpp 
# update is done. Afterwards the status in the database is updated 
# according to the return value of the program. In case one of the merpp 
# update failes, also the corresponding runnumber is inserted into the 
# database. 
# The important INFOs, WARNings and ERRORs are written not only to the 
# scriptlog but also to the processlog. 
# 
# The callisto.rc files are stored in the setup directory
#
