# This script is launching star for sequence.
# 
# In the case of star only one sequence is processed. Despite of 
# that the structure of the script is such, that also more sequences could
# be processed. The restriction to one sequence has been made, as star
# takes some time. There's one todo file per sequence. 
# First the script searches for a todo file. Then star is run for the 
# sequence from this todo file. 
#
# the star.rc files are taken from the mars directory
