Repeated Tests

The rest of the program has this structure:

    34         if (-d $source_node) {
                 ...
    41         } else {
                 ...
    50         }
    51         &xcopy($source_node) if -d $source_node;

Let's rewrite this as:

               if (-d $src_file) {
                 ...
                 xcopy($src_file, $dst_file);
               } else {
                 ...
               }
