        This package contains the common list of error and

        status codes. It is held centrally to allow

        packages to interchange error codes and status

        codes in a common way, rather than each package

        having its own conventions for error/status

        reporting. The error codes are modelled on the

        POSIX style naming e.g. EINVAL etc. This package

        also provides the standard strerror() function to

        convert error codes to textual representation, as

        well as an implementation of the errno idiom."
