 ## Taken from The Ruby Programming Language, page 110.

 # The following simple Ruby program demostrates a flip-flop. It reads a
 # text file line-by-line and prints any lines that contains the text "TODO".
 # It then continues printing lines until it reads a blank line.

 ARGF.each do |line |  # For each line of standard in or of named files
  print line if line=~/TODO/..line=~/^$/ # Print lines when flip-flop is true
 end
