use strict;
# This script is called thus :
#
# make_opengl [opengl_version]
#
# - It needs files from the OpenGL extension registry:
#
# http://www.opengl.org/registry/api/gl.spec
# http://www.opengl.org/registry/api/gl.tm
# http://www.opengl.org/registry/api/wgl.tm
# http://www.opengl.org/registry/api/wglext.spec
#
# If they are not found in the current directory the script will
# attempt to download them from there.
#
# - opengl_version is the OpenGL version emulated by the library
# (can be 1.0 to 1.5). The default is 1.1.
#
# 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).
#
# - include/wine/wgl_driver.h: definitions for the tables of OpenGL functions.
