Let's say, you have an object that you want to decorate, thus

adding new attributes and methods to it. Here is how:

```ruby

require 'decoor'

s = ' Jeff Lebowski '

d = decoor(s, br: ' ') do

  def parts

    @origin.strip.split(@br)

  end

end

assert(d.parts == ['Jeff', 'Lebowski'])

```

You may also turn an existing class into a decorator:

```ruby

require 'decoor'

class MyString

  def initialize(s, br)

    @s = s

    @br = br

  end

  decoor(:s)

  def parts

    @origin.strip.split(@br)

  end

end

d = MyString.new('Jeff Lebowski')

assert(d.parts == ['Jeff', 'Lebowski'])

```

That's it.
