+=head1 FUNCTIONS
+
+=over 4
+
+=item C<set_session_value %values>
+
+Store all key/value pairs in C<%values> in the session. All of these
+values are copied back into C<$::form> in the next request
+automatically.
+
+The values can be any Perl structure. They are stored as YAML dumps.
+
+=item C<get_session_value $key>
+
+Retrieve a value from the session. Returns C<undef> if the value
+doesn't exist.
+
+=item C<create_unique_sesion_value $value, %params>
+
+Create a unique key in the session and store C<$value>
+there.
+
+If C<$params{expiration}> is set then it is interpreted as a number of
+seconds after which the value is removed from the session. It will
+never expire if that parameter is falsish.
+
+Returns the key created in the session.
+
+=item C<expire_session_keys>
+
+Removes all keys from the session that have an expiration time set and
+whose expiration time is in the past.
+
+=item C<save_session>
+
+Stores the session values in the database. This is the only function
+that actually stores stuff in the database. Neither the various
+setters nor the deleter access the database.
+
+=item <save_form_in_session %params>
+
+Stores the content of C<$params{form}> (default: C<$::form>) in the
+session using L</create_unique_sesion_value>.
+
+If C<$params{non_scalars}> is trueish then non-scalar values will be
+stored as well. Default is to only store scalar values.
+
+The following keys will never be saved: C<login>, C<password>,
+C<stylesheet>, C<titlebar>, C<version>. Additional keys not to save
+can be given as an array ref in C<$params{skip_keys}>.
+
+Returns the unique key under which the form is stored.
+
+=item <restore_form_from_session $key, %params>
+
+Restores the form from the session into C<$params{form}> (default:
+C<$::form>).
+
+If C<$params{clobber}> is falsish then existing values with the same
+key in C<$params{form}> will not be overwritten. C<$params{clobber}>
+is on by default.
+
+Returns C<$self>.
