# the Grab interpreter splits scripts into lines;
# any line that isn't an obvious instruction is ignored;
# all leading and trailing whitespace is stripped from every line;
# all characters on a line after an instruction has been recognized is ignored;
# instructions must be the first non-whitespace position of a line or the line is ignored

# running the script makes cumulative changes to a 'working subset' of the dataset,
