============================== This distribution contains -------------------------- - NVIDIA Cg toolkit documentation in the docs directory - NVIDIA Cg compiler (cgc) in the bin directory - NVIDIA Cg runtime libraries in the lib directory - Example Cg applications in the examples directory - Under Microsoft Windows, a Cg language syntax highlighter for Microsoft Visual Studio is provided in the msdev_syntax_highlighting directory - Under Microsoft Windows, if selected at install time, 64-bit binaries and libraries are in the bin.x64 and lib.x64 directories. See the release notes (docs/CgReleaseNotes.pdf) for detailed information about this release. The Cg toolkit is available for a number of different hardware and OS platforms. As of this writing, supported platforms include: - Windows (XP, Vista, Win 7) on x86/x86-64 - Linux on x86/x86-64 - Mac OS X (Tiger, Leopard, Snow Leopard) on ppc/i386/x86_64 - Solaris 10 on x86/x86-64 Visit the NVIDIA Cg website at http://developer.nvidia.com/page/cg_main.html for updates and complete compatibility information.
