+/// @brief Parser for the configuration parameters pertaining to the
+/// processing of expired leases.
+///
+/// This parser iterates over parameters stored in the map and tries to
+/// set the appropriate values in the @c CfgExpiration object of the
+/// Configuration Manager.
+///
+/// Currently supported parameters are:
+/// - reclaim-timer-wait-time,
+/// - flush-reclaimed-timer-wait-time,
+/// - hold-reclaimed-time,
+/// - max-reclaim-leases,
+/// - max-reclaim-time,
+/// - unwarned-reclaim-cycles.
+///
+/// These parameters are optional and the default values are used for
+/// those that aren't specified.
+///
+/// The parser checks if the values of the specified parameters are within
+/// the allowed ranges and throws exception if they aren't. Each parameter
+/// has a corresponding maximum value defined in the @c CfgExpiration class.
+/// None of them may be negative.
