+=head1 NAME
+
+Plack::Session::Store - Basic in-memory session store
+
+=head1 SYNOPSIS
+
+  use Plack::Builder;
+  use Plack::Middleware::Session;
+  use Plack::Session::Store;
+
+  my $app = sub {
+      return [ 200, [ 'Content-Type' => 'text/plain' ], [ 'Hello Foo' ] ];
+  };
+
+  builder {
+      enable 'Session'; # this is the defalt store
+      $app;
+  };
+
+=head1 DESCRIPTION
+
+This is a very basic in-memory session data store. It is volatile
+storage and not recommended for multiprocessing environments. However
+it is very useful for development and testing.
+
+This should be considered the store "base" class (although
+subclassing is not a requirement) and defines the spec for
+all B<Plack::Session::Store::*> modules. You will only
+need to override a couple methods if you do subclass. See
+the other B<Plack::Session::Store::*> for examples of this.
+
+=head1 METHODS
+
+=over 4
+
+=item B<new ( %params )>
+
+No parameters are expected to this constructor.
+
+=back
+
+=head2 Session Data Management
+
+These methods fetch data from the session storage. It can only fetch,
+store or delete a single key at a time.
+
+=over 4
+
+=item B<fetch ( $session_id, $key )>
+
+=item B<store ( $session_id, $key, $data )>
+
+=item B<delete ( $session_id, $key )>
+
+=back
+
+=head2 Storage Management
+
+=over 4
+
+=item B<persist ( $session_id, $response )>
+
+This method will perform any data persistence nessecary to maintain
+data across requests. This method is called by the L<Plack::Session>
+C<finalize> method. The C<$response> is expected to be a L<Plack::Response>
+instance or an object with an equivalent interface.
+
+=item B<cleanup ( $session_id )>
+
+This method is called by the L<Plack::Session> C<expire> method and
+is used to remove any session data.
+
+=item B<dump_session ( $session_id )>
+
+This method is mostly for debugging purposes, it will always return
+a HASH ref, even if no data is actually being stored (in which case
+the HASH ref will be empty).

+
+All complex software has bugs lurking in it, and this module is no
+exception. If you find a bug please either email me, or add the bug
+to cpan-RT.
