+This file contains conversion from boost::tuples::tuple class instantiation to
+Python tuple and vice versa. The conversion uses Boost.Python custom r-value
+converters. Custom r-value converters allows Boost.Python library to handle
+[from|to] [C++|Python] variables conversion "on-the-fly". For example:
+
+typedef boost::tupls::tuple< int, std::string > record_t;
+
+record_t read_record();
+bool validate_record(record_t const & r);
+
+If you don't use custom r-value converters than you need to create small wrappers
+around the function or expose record_t class.
