# This is a little helper script for run_parallel.pl that runs a single instance of Cloudy
# The syntax is:
#
# run_single.pl "pwd" "command" "path_to_input_script"
#
# pwd: path to where run_parallel.pl was invoked
# command: the command that should be executed
#      if a relative path is used, it should be relative to where the input script resides!
# path_to_input_script: path to the input script relative to pwd
