module OmniAuth
  # OmniAuth::OpenID provides strategies for authenticating to providers
  # using the OpenID standard.
  #
  # # Installation
  #
  # To get just OpenID functionality:
  #
  #     gem install oa-openid
  #
  # For the full auth suite:
  #
  #     gem install omniauth
  #
  # # Stand-Alone Example
  #
  # Use the strategy as a middleware in your application:
  #
  #     require 'omniauth/openid'
  #     require 'openid/store/filesystem'
  #
  #     use Rack::Session::Cookie
  #     use OmniAuth::Strategies::OpenID, OpenID::Store::Filesystem.new('/tmp')
  #
  # Then simply direct users to '/auth/open_id' to prompt them for their OpenID identifier. You may also pre-set the identifier by passing an <tt>identifier</tt> parameter to the URL (Example: <tt>/auth/open_id?openid_url=yahoo.com</tt>).
  #
  # A list of all OpenID stores is available at http://github.com/openid/ruby-openid/tree/master/lib/openid/store/
  #
  # # OmniAuth Builder
  #
  # If OpenID is one of several authentication strategies, use the OmniAuth Builder:
  #
  #     require 'omniauth/openid'
  #     require 'omniauth/basic'  # for Campfire
  #     require 'openid/store/filesystem'
  #
  #     use OmniAuth::Builder do
  #       provider :open_id, OpenID::Store::Filesystem.new('/tmp')
  #       provider :campfire
  #     end
  #
  # # Configured Identifiers
  #
  # You may pre-configure an OpenID identifier.  For example, to use Google's main OpenID endpoint:
  #
  #     use OmniAuth::Builder do
  #       provider :open_id, nil, :name => 'google', :identifier => 'https://www.google.com/accounts/o8/id'
  #     end
  #
  # Note the use of nil, which will trigger ruby-openid's default Memory Store.
