# This script is called thus :
#
# make_opengl path_to_spec_file opengl_version
#
# - path_to_spec_file is the path to the directory where the OpenGL
# spec files are located. These files are part of the OpenGL
# sample implementation CVS tree and are located in
# CVS_ROOT/projects/ogl-sample/main/doc/registry/specs.
# You can find them on the web at the following URL :
# http://oss.sgi.com/cgi-bin/cvsweb.cgi/projects/ogl-sample/main/doc/registry/specs/
# You will need gl.tm and gl.spec.
#
# - opengl_version is the OpenGL version emulated by the library
# (can be 1.0 to 1.5).
#
# This script generates the three following files :
#
# - opengl32.spec : the spec file giving all the exported functions
# of the OpenGL32.DLL library. These functions are the one an
# application can directly link to (and are all the functions
# defined in the OpenGL core for the version defined by
# 'opengl_version').
#
# - opengl_norm.c : this file contains the thunks for all OpenGL
# functions that are defined in 'opengl32.spec'. The corresponding
# functions NEED to be defined in Linux's libGL or the library
# won't be able to be linked in.
#
# - opengl_ext.c : in this file are stored thunks for ALL possible
# OpenGL extensions (at least, all the extensions that are defined
# in the OpenGL extension registry). Contrary to 'opengl_norm.c',
# you do not need to have these extensions in your libGL to have
# OpenGL work (as they are resolved at run-time using
# glXGetProcAddressARB).
