WYSIWYM (What You See Is What You Mean) document processor
LyX is a document processor that encourages an approach to writing based on the structure of your documents, not their appearance. The author can concentrate on the content (What You See Is What You Mean). The formatting is done by the backends (like LaTeX) and the output can have different formats, such as DVI, postscript, PDF, html.
