        # IO.each_line

(from ruby core)
---
    each_line(*args)

---

Executes the block for every line in *ios*, where lines are separated by
*sep*. *ios* must be opened for reading or an IOError will be raised.

If no block is given, an enumerator is returned instead.

    f = File.new("testfile")
    f.each {|line| puts "#{f.lineno}: #{line}" }

*produces:*

    1: This is line one
    2: This is line two
    3: This is line three
    4: And so on...

See IO.readlines for details about getline_args.
