# Usage: config2csv path.csv [ "scenario1 scenario2 ..." ]
#
# By default, this script will take the list of scenarios from the CFLIST
# file in that directory, otherwise it will consider only the scenarios
# specified on the command line.  It will examine each scenario's file
# and also its .boot file, if present, and create a column in the .csv
# output file.  Note that "CFLIST" is a synonym for all the scenarios in the
# CFLIST file, which allows easy comparison of those scenarios with selected
# scenarios such as BUSTED that are normally omitted from CFLIST files.
