# This adds the necessary components to get backports for ubuntu and debian
#
# == Parameters

#   manually can cause undefined behavior. (Read: universe exploding)
#
# [*pin_priority*]
#   _default_: 200
#
#   The priority that should be awarded by default to all packages coming from
#   the Debian Backports project.
#
# == Examples
#
#   include apt::backports
#
#   class { 'apt::backports':
#     release => 'natty',
#   }
#
# == Authors
#
# Ben Hughes, I think. At least blame him if this goes wrong.
# I just added puppet doc.
