OpenGL and cylindrical texture mapping

Unfortunately cylindrical texture mapping isn't built into OpenGL. I would like to discuss algorithms on how to do it. I've been reading quite a bit of things about converting a point on the object into a point on my cylinder, and then converting that point on the cylinder into a point in texture space. I think I'm am not understanding some of the math. Would anyone care to talk about it? I understand that the cylinder essentially IS the texture map...but I don't see how to associate a point on it with a point on a 2D texture map.
