I think this is nothing special; if somebody has coded a _solution_, he
(hopefully) knows what he has done.

To learn perl, you have to spend hours and hours studying books/docs/examples,
thinking, trying etc.

Generally, as preciser a question is formulated, as bigger the chance that the
answer is precise too. If you have the luck to get an answer from a guru (I'm
not a guru), he will point you to good resources for learning.

On the other side, it can hinder from learning, since one can simply _run_ the
script without even trying to understand it.

If you have searched for scripts, and found at least one, you already have an
example how to put code into a script.
