Chapter 10, More Control Structures
	- lnr_example.pl is a demonstration of last, next, and redo (lnr)

	- numbers.txt is a list of numbers you can sort in the exercises. Use
	this with Exercise 14.1 (page 246).

	don’t have to type the first name/last name hash yourself. Use this
	with Exercise 14.2 (page 246).

Chapter 16, Process Management
	- We provide a fake_date.pl command that you can use in place

	to search for character names. Use this with Exercise 17.1 (page 293).
