Using rufus scheduleri n ruby script
===

Well. I'm trying to write simple scheduler in ruby, just simple script which once started will every for ex. minute do something I want. 

I've been using already rufus-scheduler with Ruby On Rails, but this time I dont' really need all framework, because it will be just simple script.

So, I've wrote something like this: 

    require 'rubygems'; require 'rufus/scheduler'

    scheduler = Rufus::Scheduler.start_new

    scheduler.every '5s' do
    	puts "Helo"
    end

and when I'm starting it (I'm using Win Vista) it does actually nothing.

    D:\>ruby scheduler.rb
    
    D:\>

I've checked this out in irb, and.. it works. 

    irb(main):002:0> require 'rubygems'; require 'rufus/scheduler'
    => true
    irb(main):003:0> scheduler = Rufus::Scheduler.start_new
    => #<Rufus::Scheduler::PlainScheduler: [...]
    irb(main):004:0> scheduler.every '5s' do
    irb(main):005:1* puts "Hello"
    irb(main):006:1> end
    => #<Rufus::Scheduler::EveryJob:0x2e6fcb0 @scheduler=#<Ruf [...]
    irb(main):007:0> Hello
    Hello
    Hello

Can someone help me with this?
Thanks in advance.
