+Oggz 0.9.7 Release
+------------------
+
+Oggz comprises liboggz and the command-line tools oggzinfo, oggzdump,
+oggzdiff, oggzmerge, oggzrip, oggz-comment, oggz-scan and oggz-validate.
+
+liboggz is a C library providing a simple programming interface for reading
+and writing Ogg files and streams. Ogg is an interleaving data container
+developed by Monty at Xiph.Org, originally to support the Ogg Vorbis audio
+format.
+
+This release is available as a source tarball at:
+
+http://www.annodex.net/software/liboggz/download/liboggz-0.9.7.tar.gz
+
+New in this release:
+--------------------
+
+This release adds a new oggz-sort tool, includes fixes for serialno generation
+on 64bit (LP64) platforms, and adds decoding of FLAC vorbiscomment packets and
+basic support for the Ogg mapping of the experimental CELT codec. It also
+includes various API additions, documentation updates and new example code.
+
+
+Details:
+--------
+
+Tools:
+        * Added new oggz-sort tool: Sort the pages of an Ogg file in order
+          of presentation time. (See below for rationale and usage).
+        * 'oggzdiff --revert' fixes for long oggzdump packetinfo lines
+        * oggz-comment: Modified to copy data pages verbatim.
+        * oggzinfo: Fixed for skeleton interpretation on big-endian hosts.
+        * oggzinfo: Various cleanups in skeleton.c (ogg.k.ogg.k)
+
+Documentation:
+        * Updated known (non-experimental) content types in all man pages.
+	* Added information about the use of oggz_tell_granulepos() in
+          OggzReadCallbacks for retrieving calculated granulepos values.
+
+Examples:
+        * Added modify-headers example, demonstrating how to write a program
+          which modifies Ogg header packets but leaves data pages intact.
+
+liboggz API:
+        * Added oggz_comments_copy().
+        * Added oggz_comments_generate(), which does not require a packet_type
+          argument. Deprecate oggz_comment_generate().
+        * Added oggz_stream_get_numheaders(), implemented for all known codecs
+        * oggz_serialno_new() now only generates serialnos which will fit
+          within a 32bit integer.
+        * oggz_write_feed() now fails with OGGZ_ERR_BAD_SERIALNO if it is
+          passed a serialno outside of the 32bit range.
+        * Added OGGZ_CONTENT_CELT to the public OggzStreamContent enum.
+
+Internal:
+        * Fixed a bunch of x86-64 compiler warnings. (Erik de Castro Lopo)
+        * Updated acinclude.m4 to latest ogg.m4. (Ivo Gonçalves)
+        * Added basic support for (experimental) Ogg mapping for CELT codec.
+        * libtool shared version info updated to 5:0:4
+
+
+oggz-sort: Rationale and usage directions
+-----------------------------------------
+
+Some encoders produce files with incorrect page ordering; for example,
+some audio and video pages may occur out of order. Although these files
+are usually playable, it can be difficult to accurately seek or scrub
+on them, increasing the likelihood of glitches during playback. Players
+may also need to use more memory in order to buffer the audio and video
+data for synchronized playback, which can be a problem when the files
+are viewed on low-memory devices.
+
+The tool oggz-validate can be used to check the relative ordering of
+packets in a file. If out of order packets are reported, use oggz-sort
+to fix the problem.
+
+About Oggz
+----------
+
+Oggz comprises liboggz and the command-line tools oggzinfo, oggzdump,
+oggzdiff, oggzmerge, oggzrip, oggz-comment, oggz-scan, oggz-sort  and
+oggz-validate.
+
+liboggz supports the flexibility afforded by the Ogg file format while
+presenting the following API niceties:
+
+        * Full API documentation
+
+        * Comprehensive test suite of read, write and seeking behavior.
+        The entire test suite can be run under valgrind if available.
+
+        * Developed and tested on GNU/Linux, Darwin/MacOSX, Win32 and
+        Symbian OS. May work on other Unix-like systems via GNU autoconf.
+        For Win32: nmake Makefiles, Visual Studio .NET 2003 solution files
+        and Visual C++ 6.0 workspace files are provided in the source
+        distribution.
+
+        * Strict adherence to the formatting requirements of Ogg bitstreams,
+        to ensure that only valid bitstreams are generated; writes can fail
+        if you try to write illegally structured packets.
+
+        * A simple, callback based open/read/close or open/write/close
+        interface to raw Ogg files.
+
+        * Writing automatically interleaves with packet queuing, and provides
+        callback based notification when this queue is empty
+
+        * A customisable seeking abstraction for seeking on multitrack Ogg
+        data. Seeking works easily and reliably on multitrack and multi-codec
+        streams, and can transparently parse Theora, Speex, Vorbis, FLAC,
+        CMML, CELT and Ogg Skeleton headers without requiring linking to those
+        libraries. This allows efficient use on servers and other devices
+        that need to parse and seek within Ogg files, but do not need to do
+        a full media decode.
+
+Full documentation of the liboggz API, customization and installation,
+and mux and demux examples can be read online at:

+
+Tools
+-----
+
+The Oggz source tarball also contains the following command-line tools,
+which are useful for debugging and testing Ogg bitstreams:
+
+        * oggzinfo: Display information about one or more Ogg files and
+        their bitstreams.
+
+        * oggzdump: Hexdump packets of an Ogg file, or revert an Ogg file
+        from such a hexdump.
+
+        * oggzdiff: Hexdump the packets of two Ogg files and output
+        differences.
+
+        * oggzmerge: Merge Ogg files together, interleaving pages in order
+        of presentation time.
+
+        * oggzrip: Extract one or more logical bitstreams from an Ogg file.
+
+        * oggz-comment: List or edit comments in an Ogg file.
+
+        * oggz-scan: Scan an Ogg file and output characteristic landmarks.
+
+        * oggz-sort: Sort the pages of an Ogg file in order of presentation
+        time.
+
+        * oggz-validate: Validate the Ogg framing of one or more files.
