Bug 568691 fixups: alter mockObjects.js so that it registers its mock by contractID but doesn't replace the CID. Fix the generic classinfo not to assert when code asks for the class description (which is no longer implemented).

WHAT'S HERE:

This source distribution includes libogg and nothing else.  Other modules 
(eg, the modules vorbis, vorbis-tools and vorbis-plugins for the Vorbis 
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 and codebooks

./doc           Ogg specification documents

./win32		Win32 projects and build automation

./macosx	MacOS X project and build files

./macos		Classic MacOS 9 projects and build automation

./debian        Rules/spec files for building Debian .deb packages
		(may not be present, depending on your distribution)

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 'http://www.xiph.org/ogg/'.
Up to date technical documents, contact information, source code and
pre-built utilities may be found there.

BUILDING FROM REPOSITORY SOURCE:

A standard svn build should consist of nothing more than:

./autogen.sh
make 

and as root if desired :

make install

This will install the Ogg libraries (static and shared) into
/usr/local/lib, includes into /usr/local/include and API manpages
(once we write some) into /usr/local/man.

BUILDING FROM TARBALL DISTRIBUTIONS:

./configure
make

and optionally (as root):
make install

BUILDING RPMS:

RPMs may be built by:

make dist
rpm -ta libogg-<version>.tar.gz

BUILDING ON WIN32:

Use the project file in the win32 directory.  It should compile out of the box.
You can also run one of the batch files from the commandline.

E.g.: build_ogg_dynamic

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:

    ./configure --host=i586-mingw32msvc --target=i586-mingw32msvc \
         --build=i586-linux
    make
    make check

The above has been tested with the following versions of the tools on
Ubuntu's Hardy Heron release:

    mingw32             4.2.1.dfsg-1ubuntu1
    mingw32-binutils    2.17.50-20070129.1-1
    mingw32-runtime     3.13-1
    wine                0.9.59-0ubuntu4

BUILDING ON MACOS 9:

Ogg on MacOS 9 is built using CodeWarrior 5.3.  To build it, first
open ogg/mac/libogg.mcp, switch to the "Targets" pane, select
everything, and make the project.  In ogg/mac/Output you will now have
both debug and final versions of Ogg shared libraries to link your
projects against.

To build a project using Ogg, add access paths to your CodeWarrior
project for the ogg/include and ogg/mac/Output folders.  Be sure that
"interpret DOS and Unix paths" is turned on in your project; it can be
found in the "access paths" pane in your project settings.  Now simply
add the shared libraries you need to your project (OggLib at least)
and #include "ogg/ogg.h" wherever you need to acces Ogg functionality.

(Build instructions for Ogg codecs such as vorbis are similar and may
be found in those source modules' README files)
