LyX is a wordprocessor frontend to LaTeX, which gives both the
ease-of-use of a wordprocessor, and the flexibility and power of
LaTeX.

Quasi-WYSIWYG interface, many LaTeX styles and layouts automatically
generated. Speeds up learning LaTeX and makes complicated layouts
easy and intuitive. Features include spell-checking, international
character support, WYSIWYG graphics, tables, and equations.

This version of LyX uses the Qt toolkit for the graphical interface.
