LaTeX
What?
What is LaTeX?. LaTeX is a powerful document preparation system based on Donald Knuth's TeX typesetting system. In fact LaTeX is just a collection of macros that transform your LaTeX commands into TeX commands which can be then "compiled" to form the final document.
Anyways, if you don't know what LaTeX is I encourage you to do some research on the internet. The learning curve is a little steep, but after you get used you won't want to go back!. A good place to start is the LaTeX project homepage, and its introduction to LaTeX
