Would you like to apply only a single SmPL rule here?

Command parameters like â--jobs 8 --chunksize 1â can be also helpful
for a parallel execution of the desired software transformation.

I suggest to consider another possibility for a bit of fine-tuning in the shown
SmPL script if you would eventually care for nicer run time characteristics
for the application of such a SmPL disjunction.
How do you think about to order the elements according to a probable
function call frequency?
