+Active Record Session Store
+===========================
+
+A session store backed by an Active Record class. A default class is
+provided, but any object duck-typing to an Active Record Session class
+with text `session_id` and `data` attributes is sufficient.
+
+The default assumes a `sessions` tables with columns:
+
+*  `id` (numeric primary key),
+*  `session_id` (string, usually varchar; maximum length is 255), and
+*  `data` (text or longtext; careful if your session data exceeds 65KB).
+
+The `session_id` column should always be indexed for speedy lookups.
+Session data is marshaled to the `data` column in Base64 format.
+If the data you write is larger than the column's size limit,
+ActionController::SessionOverflowError will be raised.
+
+You may configure the table name, primary key, and data column.
+For example, at the end of `config/application.rb`:
+
+    ActiveRecord::SessionStore::Session.table_name = 'legacy_session_table'
+    ActiveRecord::SessionStore::Session.primary_key = 'session_id'
+    ActiveRecord::SessionStore::Session.data_column_name = 'legacy_session_data'
+
+Note that setting the primary key to the `session_id` frees you from
+having a separate `id` column if you don't want it. However, you must
+set `session.model.id = session.session_id` by hand!  A before filter
+on ApplicationController is a good place.
+
+Since the default class is a simple Active Record, you get timestamps
+for free if you add `created_at` and `updated_at` datetime columns to
+the `sessions` table, making periodic session expiration a snap.
+
+You may provide your own session class implementation, whether a
+feature-packed Active Record or a bare-metal high-performance SQL
+store, by setting
+
+    ActiveRecord::SessionStore.session_class = MySessionClass
+
+You must implement these methods:
+
+* `self.find_by_session_id(session_id)`
+* `initialize(hash_of_session_id_and_data, options_hash = {})`
+* `attr_reader :session_id`
+* `attr_accessor :data`
+* `save`
+* `destroy`
+
+The example SqlBypass class is a generic SQL session store. You may
+use it as a basis for high-performance database-specific stores.
