Chapter 8, Part One.

Chapter 8 in Learning Perl is lengthy, I don't think I can understand
them very well without running a few scripts copied down from the book.
I have been thinking about how I can manage the testing scripts well,
making them easy to run, comprehend, review and modify. Now I've come up with
a solution, which requires immediate termination of composing testing scripts
in chapter 8. Life is short, but long enough for me to mess with Perl scripting,
in the best ways I can think of.
