TK/AUX toolkit/library

Ok, so I am pretty much a newbie to OpenGL and I have been trying to do some of the programs from NeHe - very good, if I might add - but the problem is there are two header files that my computer cannont find and I don’t know where they are either. They are the “aux.h” and “tk.h” header files. I’ve heard that they are already included with OpenGL, but I can’t find them anywhere, and w/o them I can’t program what I want! AHHH! Can anyone help me!??!? Thanx a bunch!

AUX is outdated so many newer compilers do not include the headers/lib.
