The installation method of using a cord as described by others is exactly the way windshields were installed in the past. I would use a smaller line for the 'rip' cord, something like a chalk line, or a little larger, rather than the 1/4" rope mentioned. I will emphasize what was said eariler, that you start seating the glass at the bottom, so gravity helps. Start in the center of the glass and work both ways around the glass. I would further suggest that you have a couple of feet extra cord for pulling on, and hang on to one end while you pull the other; then switch and pull on the other side, to work the glass evenly. The slapping is usually necessary, but I have found that putting your hands flat on the glass and pulling downward while pushing inward, gently, also helps. Be especially cautious around the side curves in the glass. Slapping/pounding at the curve can break the glass, and pushing sideways on the side portion of the glass is a sure way to break it, although you may have to push lightly there to seat the glass.

The cement mentioned by someone should not be used, if the reference is actually to an adhesive cement, but originally a caulking compound was used. Caulking is messy, but it doesn't have the adhesive quality of 'cements.' You can use caulking if you want to- the hardware store stuff for window caulking, as long as it is considered non-hardening.
