-/* PACKAGE
-
-   disk-label - all knowing disk I/O package
-
-   DESCRIPTION
-
-   The disk-label package provides a generic interface to disk
-   devices.  It uses the arguments specified when an instance is being
-   created to determine if the raw disk, a partition, or a file within
-   a partition should be opened.
-
-   An instance create call to disk-label could result, for instance,
-   in the opening of a DOS file system contained within a dos
-   partition contained within a physical disk.
