-------------------RELEASE INFORMATION-------------------This release builds the Cg compiler (cgc.exe) with the "generic" profile,which does some minimal semantic checks and prints out a tree representationof the code.  It can be built either with the included Microsoft Visual C++ 6.0 projectsand workspace, or with the included Makefile.The release contains a pre-built parser (parser.c and parser.h) builtfrom parser.y with GNU bison.  Rebuilding will require GNU bison ifyou make any changes to parser.yThis release contains the front-end to the compiler, plus a 'trivial'back-end (profile) that does some limited checking and outputs a parse treeto stdout. This back-end is almost entirely encapsulted in generic_hal.[ch]hal.[ch] describes the hardware abstraction layer by which profilescommunicate with the front-end.  To add a new profile, you can usegeneric_hal.c as a framework/example.  A profile must register itselfwith the HAL by calling RegisterProfile as part of compiler startup.Then, if selected via the appropriate command line argument, theprofile will be called to verify various constructs in the source code,deal with connector semantics, and finally, generate code.  Seegeneric_hal.c for more details. The directory contains 4 examples: vertexlight.cg, vertexlight4.cg,position.cg, and reflection.cg. After building cgc.exe, you can usefollowing command line to compile these:   cgc -profile generic <example_file_name>This release prints the output to stdout only.Developers can download all the latest Cg-related content from the Cg website at:http://www.nvidia.com/Cg-------LICENSE-------Copyright (c) 2002, NVIDIA Corporation.NVIDIA Corporation("NVIDIA") supplies this software to you inconsideration of your agreement to the following terms, and your use,installation, modification or redistribution of this NVIDIA softwareconstitutes acceptance of these terms.
