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 representation
of the code.  It can be built either with the included Microsoft Visual C++ 6.0 projects
and workspace, or with the included Makefile.

The release contains a pre-built parser (parser.c and parser.h) built
from parser.y with GNU bison.  Rebuilding will require GNU bison if
you make any changes to parser.y

This release contains the front-end to the compiler, plus a 'trivial'
back-end (profile) that does some limited checking and outputs a parse tree
to stdout. This back-end is almost entirely encapsulted in generic_hal.[ch]

hal.[ch] describes the hardware abstraction layer by which profiles
communicate with the front-end.  To add a new profile, you can use
generic_hal.c as a framework/example.  A profile must register itself
with the HAL by calling RegisterProfile as part of compiler startup.
Then, if selected via the appropriate command line argument, the
profile will be called to verify various constructs in the source code,
deal with connector semantics, and finally, generate code.  See
generic_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 use
following command line to compile these: 
  cgc -profile generic <example_file_name>
This release prints the output to stdout only.
