For me, using App-s2p-1.003 and perltidy v20170521, it works
as long as I start with the previous version of
Gen_dummy_probes.pl in place. I first tried to test this by
"rm Gen_dummy_probes.pl; make Gen_dummy_probes.pl", and what
I got was a script without all the initial commentary nor
the first line of actual Perl code.

I don't think this is good practice; it implies that any
accidental corruption of the commentary would be carried
forward. I think we should be extracting the commentary
from Gen_dummy_probes.sed.
