+This README covers the Ogg Vorbis 'Tremor' integer playback codec
+source as of date 2002 04 03, version 1.0.0.
+
+ ****
+
+IMPORTANT: Unlike most commonly available Xiph.Org source code, this
+package is Commercial software! It is neither BSD licensed nor a
+variant of the GPL. As such, Xiph.Org reserves redistribution
+rights, subject to agreed upon licensing terms.
+
+ ******
+
+The C source in this package will build on any ANSI C compiler and
+function completely and properly on any platform. The included build
+system assumes GNU build system and make tools (m4, automake,
+autoconf, libtool and gmake). GCC is not required, although GCC is
+the most tested compiler. To build using GNU tools, type in the
+source directory:
+
+./autogen.sh
+make
+
+Currently, the source implements playback in pure C on all platforms
+except ARM, where a [currently] small amount of assembly (see
+asm_arm.h) is used to implement 64 bit math operations and fast LSP
+computation. If building on ARM without the benefit of GNU build
+system tools, be sure that '_ARM_ASSEM_' is #defined by the build
+system if this assembly is desired, else the resulting library will
+use whatever 64 bit math builtins the compiler implements.
+
+No math library is required by this source. No floating point
+operations are used at any point in either setup or decode. This
+decoder library will properly decode any past, current or future
+Vorbis I file or stream.
+
+ ********
+
+The build system produces a static and [when supported by the OS]
+dynamic library named 'libvorbisidec'. This library exposes an API
+nearly identical to the BSD reference library's 'libvorbisfile',
+including all the features familiar to users of vorbisfile. This API
+is similar enough that the proper header file to include is named
+'ivorbisfile.h' [included in the source build directory]. Lower level
+libvorbis-style headers and structures are in 'ivorbiscodec.h'
+[included in the source build directory]. A simple example program,
+ivorbisfile_example.c, can be built with 'make ivorbisfile_example'.
