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