Subject: checking for blank line

Hello,
 I know this is an elementary problem, but I have been fooling around
with RoR for a little while and am now in need of doing some ruby
scripting. I am reading a text file line by line and I want to check if
the line is empty. For example:

file = File.new("test.txt", "r")
while (line = file.gets)
  @array = line.split(':')
    if @array[0] == 'cn'
      puts "#{@array[1]}"
    end
    if @array[0] == 'title'
      puts "   Title: #{@array[1]}"
    end
    if @array[0] == 'company'
      puts "   Company: #{@array[1]}"
    end
    if @array[0] == nil              #~ THIS IS THE LINE I'M TALKING
ABOUT
      puts "-----"
    end
end
file.close

The input file just looks like this:

cn: John Smith
title: executive
company: ReallyCoolSoftware, inc.

cn: John Doe
title: janitor
company: NotSoCoolSoftware, inc.

etc...

How can I pick up those blank lines in my IF statement? I tried nil and
'', but neither seem to work.

Any help is appreciated!
Thank you!!
 - Jeff
