These are a few of my favorite things:

#!/usr/local/bin/perl

use strict;
use warnings;
use CPAN::FindDependencies;
use ExtUtils::MakeMaker qw(prompt);
    
my $mod = prompt("Enter module name: ");

my @dependencies = CPAN::FindDependencies::finddeps($mod);
    foreach my $dep (@dependencies) {
    print ' ' x $dep->depth();
    print $dep->name().' ('.$dep->distribution().")\n";
  }

And this:

#!/usr/local/bin/perl

use strict;
use warnings;
use B::PerlReq;
use ExtUtils::MakeMaker qw(prompt);

    my $mod = prompt("Enter path to .pm: ");
    my $prereq = system("perl -MO=PerlReq -d $mod");
    print "$prereq\n";

And this:

#!/usr/local/bin/perl

use strict;
use warnings;
use ExtUtils::MakeMaker qw(prompt);

    
my $mod = prompt("Enter module name: ");
my $info = system("module_info -a $mod");
print "$info\n";
