still, for cutter to get this to work with strict, %opts will need to be declared first.
something like:
my %opts;
getopts( "J:f:s:", \%opts )
or die "error message...";
## --or, all in one (shorter but not as clear)--
getopts( "J:f:s:", \my %opts )
or die "...";
will have all the advantages you mentioned, and be strict compliant.
