 /** @file
  *
- * Buffers for loading files.
- *
- * This file provides routines for filling a buffer with data received
- * piecemeal, where the size of the data is not necessarily known in
- * advance.
- *
- * Some protocols do not provide a mechanism for us to know the size
- * of the file before we happen to receive a particular block
- * (e.g. the final block in an MTFTP transfer).  In addition, some
- * protocols (all the multicast protocols plus any TCP-based protocol)
- * can, in theory, provide the data in any order.
- *
- * Rather than requiring each protocol to implement its own equivalent
- * of "dd" to arrange the data into well-sized pieces before handing
- * off to the image loader, we provide these generic buffer functions
- * which assemble a file into a single contiguous block.  The whole
- * block is then passed to the image loader.
- *
- * Example usage:
- *
- * @code
- *
- *   struct buffer my_buffer;
- *   void *data;
- *   off_t offset;
- *   size_t len;
- *   
- *   // We have an area of memory [buf_start,buf_end) into which we want
- *   // to load a file, where buf_start and buf_end are physical addresses.
- *   buffer->start = buf_start;
- *   buffer->end = buf_end;
- *   init_buffer ( &buffer );
- *   ...
- *   while ( get_file_block ( ... ) ) {
- *     // Downloaded block is stored in [data,data+len), and represents 
- *     // the portion of the file at offsets [offset,offset+len)
- *     if ( ! fill_buffer ( &buffer, data, offset, len ) ) {
- *       // An error occurred
- *       return 0;
- *     }
- *     ...
- *   }
- *   ...
- *   // The whole file is now present at [buf_start,buf_start+filesize),
- *   // where buf_start is a physical address.  The struct buffer can simply
- *   // be discarded; there is no done_buffer() call.
- *
- * @endcode
- *
- * For a description of the internal operation, see \ref buffer_int.
