+ * The sideload-host protocol serves the data in a file (given on the

+ *
+ * - The connect message includes the total number of bytes in the
+ * file and a block size chosen by us.
+ *
+ * - The other side sends the desired block number as eight decimal
+ * digits (eg "00000023" for block 23). Blocks are numbered from
+ * zero.
+ *
+ * - We send back the data of the requested block. The last block is
+ * likely to be partial; when the last block is requested we only
+ * send the part of the block that exists, it's not padded up to the
+ * block size.
+ *
+ * - When the other side sends "DONEDONE" instead of a block number,
+ * we hang up.
