Greetings, fellow monks.

Suppose I have a zip file that includes file1, file2 and file3 and a directory that includes file1 and file2, different from the one in zip.

I want to write a Perl script that can point out that file3 does not exist in the directory and that file2 is different.

Now, I've tried implementing that with a MANIFEST-like file, but is there a more efficient solution?
