# Revision 3: 
#
# Just define the method, don't declare which sequences 
# this hook will be executed in. 
#
# More meaningful sequence names, following rails naming conventions
# for familiarty. 
#
# pre  -> before_process
# in   -> before_render
# post -> after_process

require 'growl'

module Jekyll
  class GrowlHook < Hook
    def before_process
      Growl.notify 'Building...', :title => 'Jekyll'
    end
    
    def after_process
      Growl.notify 'Build complete', :title => 'Jekyll'
    end
  end
end

# Revision 2:
#
# Sequence becomes the method, instead of passing it in
