Latex is one of the best type setting tool compared to any other type setters. TeX is essentially a Markup Language (like HTML, XML and RTF). The typeset quality of Latex is incomparable. If u want to  make a technical paper or a thesis , Latex is the best choice. It is easy to include math formulas and charts. Also the source file format  is not bound to a particular OS or platform. Latex is totally free.

A Latex file is first made with  ‘.tex’ extension. It is then compiled and converted to pdf or ps format file. Some of the Latex environments are kile, lyx etc. Some of the tex ediitors are Texnic-center, Wintex, Winedit, Texmaker, Texworks etc. The commonly used latex engines are Miktex and Tex live. Viewers are Yap, Ghost view, Adobe Reader etc.
