Greetings, I have noticed using the DirCompare.pm module that during a comparison of two directories, the comparison only searches for matching files "files with the same file name but different content" at the same "level" of the directory tree, I have noticed this same functionality with most comparison programs no matter what language they are written in, I understand the purpose behind only searching for matching files with matching names at the same level of the directory tree because files with matching names can exist in different folders but my question is how could one go about modifying DirCompare.pm to search all levels of the two directories being compared for matching files and unique files. Here is the code i am using along with DirCompare.pm Thanks for your time amd help. 
use File::DirCompare;
use File::Basename;

$x='directory1';

$y='directory2';

File::DirCompare->compare("$x","$y", sub {
    my ($a, $b) = @_;
    if (! $b) {
      printf "Only in %s: %s\n", dirname($a), basename($a);
      
      
      } elsif (! $a) {
      printf "Only in %s: %s\n", dirname($b), basename($b);
      
      
    } else  {
      print "Files $a and $b differ\n";
  }

    });
