Extension module support methods
 
This module provides the tools required to check whether
an extension is available

Classes
		object _Alternate   class _Alternate(object)       Methods defined here: __call__(self, *args, **named) Call, doing a late lookup and bind to find an implementation __init__(self, name, *alternates) Initialize set of alternative implementations of the same function __nonzero__(self) Data descriptors defined here: __dict__ dictionary for instance variables (if defined) __weakref__ list of weak references to the object (if defined) Data and other attributes defined here: implementation = None resolved = False

Functions
		alternate(name, *functions) Construct a callable that functions as the first implementation found of given set of alternatives hasGLExtension(specifier) Given a string specifier, check for extension being available hasGLUExtension(specifier) Given a string specifier, check for extension being available
