	There is also mathematically nice recipe for picking random line from
	the file. In Perl at
	http://www.oreilly.com/catalog/cookbook/chapter/ch08.html#chap08_picking_0
	and in Python at
	http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/59865

	It is ecological, by not reading entire file into the array of
	strings. It is easy to write the same in Ruby.
