Multi-texturing is the process of taking two textures and getting a color from each, then combining them to get the color to render to the screen.  By using GLSL, this process can be greatly simplified compared to using the conventional fixed-function pipeline approach.  The multi-texturing tutorial shows how to easily modulate two textures using a shader.
