        This package contains the common list of error and
60
        status codes. It is held centrally to allow
61
        packages to interchange error codes and status
62
        codes in a common way, rather than each package
63
        having its own conventions for error/status
64
        reporting. The error codes are modelled on the
65
        POSIX style naming e.g. EINVAL etc. This package
66
        also provides the standard strerror() function to
67
        convert error codes to textual representation, as
68
        well as an implementation of the errno idiom."
