No more endless tinkering with formatting details, “finger painting” font attributes or futzing around with page boundaries. LyX is for people who want their writing to look great, right out of the box. A broad array of ready, well-designed document layouts are built in. But you can also use LyX to create a letter or a novel or a theatre play or film script. In addition, staples of scientific authoring such as reference list and index creation come standard. This results in world-class support for creation of mathematical content (via a fully integrated equation editor) and structured documents like academic articles, theses, and books. LyX combines the power and flexibility of TeX/ LaTeX with the ease of use of a graphical interface. LyX is a document processor that encourages an approach to writing based on the structure of your documents ( WYSIWYM) and not simply their appearance ( WYSIWYG).
