+ ogg_stream_pageout_fill())
+* Correct possible buffer overwrite in stream encoding on 32 bit
+ when a single packet exceed 250MB.
+* Correct read-buffer overrun [without side effects] under
+ similar circumstances.
+* Update unit testing to work properly with new page spill
+ heuristic.
+
+Version 1.2.0 (2010 March 25)
+
+* Alter default flushing behavior to span less often and use larger page
+ sizes when packet sizes are large.
+* Build fixes for additional compilers
+* Documentation updates
+
+Version 1.1.4 (2009 June 24)
+
+* New async error reporting mechanism. Calls made after a fatal error are
+ now safely handled in the event an error code is ignored
+* Added allocation checks useful to some embedded applications
+* fix possible read past end of buffer when reading 0 bits
+* Updates to API documentation
+* Build fixes
+
+Version 1.1.3 (2005 November 27)
+
+ * Correct a bug in the granulepos field of pages where no packet ends
+ * New VS2003 and XCode builds, minor fixes to other builds
+ * documentation fixes and cleanup
+
+Version 1.1.2 (2004 September 23)
+
+ * fix a bug with multipage packet assembly after seek
+
+Version 1.1.1 (2004 September 12)
+
+ * various bugfixes
+ * important bugfix for 64-bit platforms
+ * various portability fixes
+ * autotools cleanup from Thomas Vander Stichele
+ * Symbian OS build support from Colin Ward at CSIRO
+ * new multiplexed Ogg stream documentation
+
+Version 1.1 (2003 November 17)
+
+ * big-endian bitpacker routines for Theora
+ * various portability fixes
+ * improved API documenation
+ * RFC 3533 documentation of the format by Silvia Pfeiffer at CSIRO
+ * RFC 3534 documentation of the application/ogg mime-type by Linus Walleij
+
+Version 1.0 (2002 July 19)
+
+ * First stable release
+ * little-endian bitpacker routines for Vorbis
+ * basic Ogg bitstream sync and coding support

+
+= WHAT'S HERE =
+
+This source distribution includes libogg and nothing else. Other modules
+(eg, the modules libvorbis, vorbis-tools for the Vorbis music codec,
+libtheora for the Theora video codec) contain the codec libraries for
+use with Ogg bitstreams.
+
+Directory:
+
+./src The source for libogg, a BSD-license inplementation of
+ the public domain Ogg bitstream format
+
+./include Library API headers
+
+./doc Ogg specification and libogg API documents
+
+./win32 Win32 projects and build automation
+
+./macosx Mac OS X project and build files
+
+= WHAT IS OGG? =
+
+Ogg project codecs use the Ogg bitstream format to arrange the raw,
+compressed bitstream into a more robust, useful form. For example,
+the Ogg bitstream makes seeking, time stamping and error recovery
+possible, as well as mixing several sepearate, concurrent media
+streams into a single physical bitstream.
+
+= CONTACT =
+
+The Ogg homepage is located at 'https://www.xiph.org/ogg/'.
+Up to date technical documents, contact information, source code and
+pre-built utilities may be found there.
+
+BUILDING FROM TARBALL DISTRIBUTIONS:
+
+./configure
+make
+
+and optionally (as root):
+make install
+
+This will install the Ogg libraries (static and shared) into
+/usr/local/lib, includes into /usr/local/include and API
+documentation into /usr/local/share/doc.
+
+BUILDING FROM REPOSITORY SOURCE:
+
+A standard svn build should consist of nothing more than:
+
+./autogen.sh
+make
+
+and as root if desired :
+
+make install
+
+BUILDING ON WIN32:
+
+Use the project file in the win32 directory. It should compile out of the box.
+
+CROSS COMPILING FROM LINUX TO WIN32:
+
+It is also possible to cross compile from Linux to windows using the MinGW
+cross tools and even to run the test suite under Wine, the Linux/*nix
+windows emulator.
+
+On Debian and Ubuntu systems, these cross compiler tools can be installed
+by doing:
+
+ sudo apt-get mingw32 mingw32-binutils mingw32-runtime wine
+
+Once these tools are installed its possible to compile and test by
+executing the following commands, or something similar depending on
+your system:
+
+ ./configure --host=i586-mingw32msvc --target=i586-mingw32msvc \
+ --build=i586-linux
+ make
+ make check
+
+(Build instructions for Ogg codecs such as vorbis are similar and may
+be found in those source modules' README files)
