\end_layout

\begin_layout Itemize

\end_layout

\begin_layout Itemize
countlen bytes of big-endian count (count).
\end_layout

\begin_layout Standard
Records are processed as follows:
\end_layout

\begin_layout Itemize
To form the first ID encoded by record, take the first prefixlen bytes predicted
 ID and append the read ID value to it.
 The result is the first ID encoded.
\end_layout

\begin_layout Itemize
If countlen is 0, record encodes 1 ID.
\end_layout

\begin_layout Itemize
If countlen is 1, record encodes 2+count IDs.
\end_layout

\begin_layout Itemize
If countlen is 2, record encodes 258+count IDs.
\end_layout

\begin_layout Itemize
If countlen is 3, record encodes 65794+count IDs.
\end_layout

\begin_layout Itemize
The new predicted ID is the next ID after last one encoded by the record.
\end_layout

\begin_layout Standard

 by all records.
