        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."
