+			 Vector math library
+
+
+* Overview
+
+  The Vector math library provides 3-D/4-D vector operations including
+  addition, outer product, multiply by a matrix, etc.
+
+
+* License
+
+  This library is licensed under the terms in the file 'LICENSE' in
+  this directory.
+
+
+* Installing
+
+  To install this library, run following commands:
+
+  - PowerPC with VMX (fully supported)
+
+    $ make ARCH=ppu install
+
+  - SPU (Cell Broadband Engine Synergistic Processor Unit)
+
+    $ make ARCH=spu install
+
+  - x86 with SSE (partially supported)
+
+    $ make ARCH=SSE install
+
+  - Other architectures (partially supported)
+
+    $ make install
+
+
+  By default, files in the library will be placed as below:
+
+  - headers
+  
+    /usr/include/vectormath/c/       (C headers)
+    /usr/include/vectormath/cpp/     (C++ headers)
+
+  - SPU headers
+  
+    /usr/spu/include/vectormath/c/   (C headers)
+    /usr/spu/include/vectormath/cpp/ (C++ headers)
+
+  No shared library, static library nor executable is installed,
+  because all functions in this library are provided as inline
+  functions.
+
+
+* Packaging
+
+  By running following command in this directory, a source tarball
+  'vectormath-<VERSION>.tar.gz' can be created:
+
+    $ make dist
+  
+  You can also create RPM packages by executing the command below with
+  the tarball:
+
+    $ rpmbuild -tb vectormath-1.0.1.tar.gz --target=ppc
+
+  One or two packages, vectormath-devel (and, in addition,
+  spu-vectormath-devel for PowerPC target), will be created.
+
+
+* Usage
+
+  See the documents `doc/*.pdf'.
