This appears very different from what you described in your original node. Your OP talks about "automating the testing process", now you say you want "glue modules together". The former sounds like you've got three distinct application, whereas this now sounds like ... well, what exactly are you trying to do? Are these C++ libraries which you're trying to test? Are you trying to write Perl modules in C++? I still don't really know what this is about.

Also, just as a friendly pointer, noone is going to write your program for you here. If you've got difficulty with a concept or are looking for pointers at relevant documentation or are simply lost and don't even know where to start, then say so and more likely than not you will receive helpful replies. But saying "This is what I need to do" and expecting someone to write a script for you ain't gonna happen.

And I strongly recommend following McDarren's advice below.
