-   * io_ss.c
-   *
-   * Implements the Source/Sink interface.
-   *
-   * As will all I/O modules, most functions are for local use only (called
-   * via function pointers in the I/O context).
-   *
-   * The Source/Sink model is the primary 'user' interface for alternate data
-   * sources; the IOCtx interface is intended (at least in version 1.5) to be
-   * used internally until it settles down a bit.
-   *
-   * This module just layers the Source/Sink interface on top of the IOCtx; no
-   * support is provided for tell/seek, so GD2 writing is not possible, and 
-   * retrieving parts of GD2 files is also not possible.
-   *
-   * A new SS context does not need to be created with both a Source and a Sink.
-   *
-   * Written/Modified 1999, Philip Warner.
