Hello. I'm try to write cookbook LAMP

metadata.rb:

maintainer       "vase"
maintainer_email 
"
 "
license          "none"
description      "Installs/Configures LAMP package"
long_description IO.read(File.join(File.dirname(__FILE__), 'README.rdoc'))
version          "0.0.1"
depends          "apache2"

When i'm try to do :
rake metadata i get error:


 :/media/chef/site-cookbooks/LAMP#
 rake --trace  metadata
(in /media/chef)
** Invoke metadata (first_time)
